I just got 2 corydoras cats today from Petsmart and I was just watching them swim around and noticed that one of them has a kind of red belly. It's not completely red, but definitely noticeable. It's noticeable really only if he swims up the side of the glass so you get a good look at his belly. From the side you can't really tell.

If I had a picture I'd get a camera but unfortunately mines broke!

Anyway, is this some sort of infection or is it just the blood flowing through his body or something? If it's an infection, is there anything I can do for the poor guy?

What country are you in?

Without a pic it is hard to be sure, but it sounds like an infection. Can you describe the red patch? Is the patch under the skin or on top like a sore or a bruise? If it is under the skin and shows any lines like veins, We should treat right away.

It is possible that you could use a treatment of MelaFix and PimaFix, but lets make sure first. But if it looks like red viens under the surface treat right away for hemorrhagic septicemia.

it could be the fish was kept in bad water and has a minor infection or just red inflammation caused by the poor water quality. See how it goes over the next 24 hours and if it gets worse then it is probably a bacterial infection.
Also check your tank water quality to make sure that isn't the cause.

If you have to treat the fish then check the instructions on the pack. SOme medications recommend only using a half dose for catfish and other scaleless fishes.
Remove any carbon from the filter before treating.

If there are red streaks the treatment should be done quickly! Hemorrhagic septecemia progresses rapidly and fatally!

Half doses are not necessary for Corys with MelaFix and PimaFix. But it is obviously correct to read the instructions.

Corys tolerate meds well, as far as I have experience, except for salt dips.

Please describe the red patch, Reeveso.

Also describe the tank: size, tank mates, water stats, substrate, decore....

If you can not test the water yourself, then an lps/lfs will most likely help out.

Ok well the red isn't sore or bruise like..it's just a reddening of his skin. It doesn't look like red veins either.

The water quality should be fine. I've never had a problem and their tank buddy is a betta fish who's been in there over a month w/ absolutely no problems at all. I do 10% water changes daily. It's a 30 gallon tank as well (well, 29).

Water stats - there's a TINY amount of ammonia (probably less than .25) 0 nitrite 0 nitrate.

Decore - a few plants (not real) and a little "underwater car".

Substrate - Not really sure what to say about that lol. It doesn't really say anything about it on the bag. However the brand name is "Top Fin"

If it makes a difference, they're peppered cory's. Also, they both seem to be as healthy as can be. They chase each other around the tank and dart after each other like there's no tomorrow lol - it's actually pretty fun to watch.

I'll try to get a picture when I get home from school later if I can borrow someone's camera. The hard part is going to be getting the fish to come off the bottom of the tank so I can see his belly lol.

As for mela/pimafix...where can I get them? Would petsmart/zone have them - or walmart maybe? Petsmart and petzone are both about 30 minutes from my house - Walmart is only 15 lol

Also, it doesn't look any worse since last night. Maybe even a tad bit better if anything.

It all sounds good!

Try rubbing some of the substrate between your hands and see if it is sharp. Are there sharp edges on the car? Keep a sly eye on Betta. They can get temperamental and territorial as they age. They also are strangely sneaky, waiting until the boss is out of the room to be naughty.

As was said by Colin T, keep the water and substrate clean. Watch the ammonia! Chances are it will take care of itself.

Don't use MelaFix with Betta. You are in the States. If it doesn't clear up I will recommend a med that will be safe. If you are around Walmart, you might find out what kind of antibacterial meds for fresh water aquariums they have.

Do you have a quarantine tank?

Is there a filter on the tank?

I wouldn't worry too much about it. It sounds like it was just in bad water before you got it and now it is getting a bit better.
I am a bit concerned you don't have any nitrates and you have a tiny amount of ammonia. Has the tank been cycled?

Why do you need to figure out what I am doing?
We are working together. you are offering your ideas and I am offering my opinion about Reeveso's new corydoras catfish.
They came in from the petshop with a red belly and the most common cause of that is poor water quality or a bacterial infection. The fish appears to be getting better now it is in a clean tank therefore the most likely scenario was the fish were kept in a bad tank at the shop. Bad being it might have had an ammonia, nitrite or high nitrate reading. The PH could have been really low or there might have been some medication or other chemicals in the tank that were irritating the catfihs's skin.

If the fish appears to be getting better then there is no need to medicate it or move it to another tank.

Colin,

I got some medication today (Pimafix) just in case - I'll keep an eye on the fish and if it gets any worse I'll medicate them. If not I guess I'll let it heal naturally.

I'm also going to check for any sharp spots in the tank and all other recommendations everyone said.

Just in case I need to use it - what is meant by "take the carbon out of the tank" when putting the medication in....does that mean to take the filter out? If so, when do I put it back in?

some filters have carbon (a black granulated substance) in them. If your filter has carbon in it you need to remove the carbon from the filter before treating. Otherwise the carbon will absorb the medication and the fish won't get better.
The carbon is usually thrown away and after you have finished medicating the tank you can put some new carbon in the filter if you want to.
Carbon can be bought from any petshop. You can usually buy replacement carbon cartridges or carbon pads for specific makes of filter. Or you can buy carbon that is packed in a box or bag and put some in a fine mesh bag and place that in the filter.
If you do want to use carbon then try to get Activated Carbon because it works better and lasts longer than normal carbon. You should also rinse the new carbon under tap water before putting it in the tank otherwise the fine dust in the carbon will make the tank water go black.

Basically the carbon is remove from the filter but the filter is left running.

Carbon is one chemical media that is used in filters to remove pollutants. Most good filters have a mechanical component (wool or floss), a chemical component (carbon or some other media) and a biological, a place that encourages the good bacteria to grow such as a sponge or bio-wheel. Keep running the filter, but remove the chemical carbon media. If the carbon is in an insert you will replace it with mechanical media/floss or wool Before you do that put some floss or wool in the filter and let it start to mature with bacteria. If it becomes necessary to medicate then you will have some mature media to use to filter the water.

Colin_T is correct, wait to see if the fish recovers on it's own. Betta are very sensitive to some medications. MelaFix is one. That is why I asked if you have a quarantine tank. If you have to medicate, I would remove the Betta. They generaly tolerate being moved better and they don't tolerate some meds.

What test kit are you using? No nitrates is very unusual, which makes me think you are using test strips.

This is the end of my day. I will leave others to help.

I chose MelaFix and PimaFix originally because they are a common and useful treatment to have handy. MelaFix is a natural and mild antibacterial and is generally used together with PimaFix which is a natural anti fungal and is also used to encourage healing tissue. I felt if you had something to use if needed that would become part of your "medicine cabinet" you wouldn't go wrong having those two.

Most of the questions I asked are common, and I had reasons to ask them. I didn't make assumptions, but wanted to get the worst case senarios out of the way--such as hemorrhagic septicemia--which goes bad fast and was a possibility from your first description. It also is the result of bad water.

Most fish problems are the result of bad water.

Let us know how it goes.

No, I don't have a quarantine tank unfortunately so I can't take the Betta out. Can it withstand just Pimafix if I have to use it?

Also about the carbon...my filters have the carbon already inside them but I can't take the carbon out (unless maybe I cut a hole in it and manually took the carbon out - then I'd just replace the whole filter..would that work?)

I'm using the filters for a "Power Filter" if anyone is familiar w/ them.

I'm using the API test kit. I'll recheck the levels, maybe I looked at it wrong.

you will have to cut the filter cartridge open and remove the carbon that way. If you replace too much of the filter material you will upset the bacteria and end up with the tank cycling again.

Can't help you with pimafix or melafix because I don't use them. Maybe send Sue a PM and ask her.

You could put the male fighter into an icecream bucket and float that in the tank. Then it would stay warm but be isolated from the medication in the water. You would have to do small partial water changes on the bucket but that wouldn't be hard.

Hi reeveso

The reason to take out the carbon is because the carbon will scrub out the medication making it a useless exercise until the charcoal becomes exhausted.

Who makes the "Power Filter"? Usually if filters have "filter packs" there are separate packs for charcoal, bio material, etc. In cases like that you just remove the charcoal pack and that's it. On some smaller filters I've seen there is only one insert that has both the mechanical and the charcoal built into one pack. These are not good to use because in instances like this and when you have to replace the filter with a new one, you lose all of the bacteria that converts ammonia to nitrite.

If there really is only one filter pack then cut it open and take out the charcoal. I'd also start looking for a better filter.

Both medications are available at Pet Smart.

Sorry but I can't help you with the betta question.

Good luck.

My filter has both the carbon and the BIO part of it, but they're 2 seperate things so I wouldn't lose all the bacteria. There's the carbon in 1 part, and the BIO part comes after that but it's separate.

I know I'd obviously leave the BIO part in there - but I should just cut mine open to get the charcoal out, then just replace the filter after the meds go through?

After you dump the carbon... You will need to put in a new one when you finish medicating. If you put new carbon in the old one... it won't stay in. It will fall out where you cut it. If it were me I would just get some plain filter material to put where that goes and throw out the old one. You have the bio media in there. That with the new floss behind it works great. That is all I use unless I am trying to remove meds or something.
You can use lots of things for floss. You can get the sheets of it or loose... You can even get pillow stuffing from Wal-Mart or craft stores... I have even used a wash cloth (unused) before in an emergency.

Good idea ICEEGRL

I'm always looking for ways to circumvent those darn filter packs. I've tried using woman's knee highs to make my own packs, either carbon, ammo chips or bio material.

I still prefer the external tanks rather than the hang on filters as they usually have more sections.

Cheers.

One quick question - if my fish were sick w/ the bacterial infection they may possibly have, would they be acting sluggish and "sick-like"?

Because they seem to be extremely active. Whenever the lights are on they're chostnatly flying around the tank. Yesterday they weren't (although that was their first day in the tank so they might have been a little scared anyway), but today they're flying around it, chasing each other like a cat chasing a dog lol - they look like they're 100% healthy and energetic.

Those little boogers can move pretty quick too lol. They have a little "game" where 1 of them will swim towards the top and the other follows. Then 1 of them will dart down to the bottom and the other follows again. Then once in awhile 1 of them will rip across the tank and do it again..lol

It's pretty funny actually :) They're a lot more active than the Betta, I can tell you that! She's a lazy old bum.

Anyway, is it a good sign that they're this active?

Yes, Reeveso, it sounds to me like your Corys are doing the "happy to be in our new home and out of that other nasty place" dance. Corys love to dance and party. They are real party animals. Corys dance for every occasion, and that is it. The sexy courting dance starts just like it. So your Corys do like their new home.

If the Corys are doing well then don't worry about it, just as Colin_T said. You could use the "float some container" method Colin_T mentioned also. Betta can be kept most anywhere.

As ICEEGRL said you can use most anything that does not have any soap or additives to put in the filter temporarily. It is good to have some extra mechnical material on hand. It can be rinsed in bleach water and used again usually.

If the carbon is in some kind of bag or container, it can be removed and a new one replaced when the treatment is over. The filter is actually the device that pumps the water and moves it through the filter pads or media. If you can tell what the manufacturer is we will know what method it uses tp move water.

Cory_Dad doesn't like the filters that use the cartridges and bio wheels. I and other do. :)

If you decide to medicate for the bacteria, you will need the MelaFix as well. In that case you would want to remove the Cory or the Betta. If you decide to just use the PimaFix as a tonic to help the Cory heal, I THINK the Betta would be ok, but if it is not needed I wouldn't bother. If the fish starts to act sluggish or goes off to itself or doesn't eat or the red spreads, then lets use a stronger med.

Are we sure the red isn't just a light pink belly? It would be irregular shaped if it is not natural.

In some cases it is good and others it is not. I don't know how to explain the difference really. It is kind of fluid like a dance, or fast darting like a panick attack? The dance thing is ok the panick thing is a bad thing.
Also... some fish act sick from the beginning, and other act fine until it is too late to help. It just depends on the fish and the situation. It isn't always the same.
I know that wasn't much help, but sometimes it is some what complicated. That is why we always ask for as many details about everything so it will give us more info to go on. Sometimes it is something that you just had not noticed or you just didn't think of... Pictures work wonders on here too.

One thing I find odd... corys usually come out to play when the lights go off and hide when they come on. They are mostly nocturnal.
Is there enough hiding places for them?
How bright are your lights?
What is the temp in your tank?

I did think happy dance or bright light shock... lol They both look similar one is just more panicky than the other... Mine have done both... :o :lol:

The "dance" seemed pretty natural. They were literally chasing each other around like they were playing tag - so I'd say it was a pretty natural, playful darting around. Also, they've done this w/ both the lights on and off and it looked the same. They were actually just doing it a minute ago w/ the lights off.

As for hiding places, all thats really in there is 4 plants and a car. They go in the car once in awhile but they seem to enjoy being out in the open. I plan on getting another bigger hiding place for them in the next few days.

The temp is at 77 degrees - I just turned it down to 75 as I think 75 is their upper limit right? I had it up there for the betta. They're eating perfect. As soon as I drop the food in they're all over it. It's gone as fast as they can find it all and eat it.

One thing I'm actually kind of worried about is how lazy my Betta is. I got her from my sister who had her in like a 0.5 gallon jar (I felt bad for the poor thing) and she's NEVER been very active.

When I first put her in there was that cottony stuff (which I just found out is fungus) - but I've hardly seen any lately. Her fins aren't very good either - I think SHE is the 1 that needs some meds lol.

Tomorrow I'll try to take a picture and put it on here and show you all each fish. Maybe that'll help

If you have ammo chips or ammonia removing granules in the filter you should remove them unless the tank is a quarantine tank. They absorb ammonia from the water and in a normal aquarium they prevent the filter bacteria from developing because there is no ammonia for them to feed from. Then once the granules are full they stop absorbing ammonia and you get an ammonia reading and the tank starts to cycle.

You can buy fine mesh bags from the LFS to put carbon in. Alternatively buy a pair of stockings and use the legs.

Get me a list of the anti bacterial meds that are available. I think I asked before for this, and it got derailed.

It is very unlikely that it is fungus alone. It is either is a bacterial infection called as I said columnaris or it is a bacterial infection with a secondary fungal infection. If the fins are shredding then there is fin rot, an infection that Betta fins are prone to.

Are her fins shredding/have ragged white edges? Are her fins clamped? Is she bloated? Is she eating? Do her scales stick out--pinecone?

It actually sounds like your Corys may be courting. Does one have a nice fat plump belly?

If your beta does have columnaris or fin rot... she can give it to the corys. You need to be very careful with that.
Get jollysue that list of meds so you can get that stopped quickly.

It does sound like the corys are flirting. Watch for eggs stuck to the tank walls and decor. If they do lay any... your betta will probably eat them though. You may only see little round spots where the eggs were... (If your corys are male and female... )

Is the redness on the belly still getting better?

I hope it works out and all your fish are fine. A pic would be helpful to really see what it looks like. :good:

Great news!

I just looked at my Cory's and the infection or whatever it was is definitely getting better. They must like their new home :)

I also rechecked the water and it was 0 ammonia, 0 nitrites, and 5-10 nitrates.

One of their bellies has no red, the others just a tiny bit - you actually have to look for it to be able to see it.

I got 2 pictures of the Betta, which I've attached (not sure how to put a picture on a forum so if I do it wrong, someone please tell me how). I couldn't get any of the Cory's - the little boogers move too much! They wouldn't sit still for me and it's my dad's camera so I don't know how to change the shutter speed and all that to get action pics and a close up.

Anyway, take a look at the betta. Her fins have gotten about 2-3x wider since I put her in my tank and out of my sisters, but they still aren't full at all. She's about 3 years old I believe - does that have anything to do w/ it?

PS - I just took a picture of the tank w/ the lights on as well. How much more should I plant it?

I plan on gettin a few more cory's (probably a total of 4 or so), 2 angelfish, and maybe 3 swordtails. I'm going to get a seperate tank for the betta though so don't worry - I know she'd probably start fighting w/ the swordtails and angelfish lol

you need a backing for the tank and some more tall plants along the back wall to cover the heater and intake pipe.
The backing can be made from coloured cardboard or you can buy one from the LFS.
