Possibly Rotfin?

[Fish Lover Forever]

I have noticed that my male guppy has a hole in his tail. It isn't in the middle of his tail it is from the edge. I was thinking that this is Rotfin, but whatever it is there is probably some bacteria entering the tail. I have put some bacteria treatment in the tank. HELP!!

What do the edges of the hole look like? White? Fluffy? Red or pink?

How big is the tank, what other fish are in there and have you tested the water?

 

[Fish Lover Forever]

The edge of his tail is white. The tank is 36 to 40 litres. There are 6 adults 3 babies ( I am planning on rehoming 1 baby.) 2 adult guppies 3 babies, 1 damnation Molly (small), 2 Platys and 1 calm Siamese fighter which does not bother him.

Can you get a pic at all (I know it's difficult)? I would guess injury, but it's really hard to tell. Have you tested the water?

Test results from last week:

NO2: 0.5 to 1.0
NO3: 80
PH: 6.5
KH: 40
GH: 180

My vote is on the 'damnation' molly

There are several things i think you beed to look at;

1) You have nitrite, this reading should be 0 at all times, nitrite is toxic and this will manifest itself in ill fish. this needs to be removed via a large water change (80%+). Check and do this every day until you have no reading at all.

2) What is your ammonia reading? You haven't told us, this is important. Can I ask how long your tank has been set up for and how it was cycled?

3) Your nitrate is quite high. You need to change your water more often if this is a regular reading. A third weekly is a good guideline, more if you have a small tank and a lot of fish - which you do.

4) Your stocking may be a future recipe for disaster. Bettas are not community minded fish and in particular, they will go for and nip slow moving guppies. Maybe not now, but it is a combination that is unlikely to work forever. This may be where the original tear came from. Usually they will clear up, if there is clean safe water. Unfortunately with nitrite, high nitrate and potentially ammonia too, your guppy will only get better if you provide daily clean water.

Hope this helps.

Yes, all of my guppies are fast moving and my betta could not care less about them. He/she is always in her/his own world wrapping itself around the plants and thermometer in my tank. I was told this before and I was considering of re-homing the betta but she/he is REALLY calm. That is all of the sections there is so the C02 OR CO3 is the ammonia. I did a approximate 25% water change yesterday and I am just going to do another test today.

I purchased and set up the tank on 30/7/12 although I have some live plants in there and thwy were not in there from the start I added them last week. I purchased my fish on 1/8/12. I have gravel in my tank if you need to know.

My guppy is still swimming, also recently my fish tank has had little spots of white stuff on the glass. I keep cleaning it off but it keeps coming back, there is also some on the gravel. I thought it is because sometimes the fish nip at the gravel and glass. Also if you would like a photo I have provided a link for it. I have 2 breeding tanks when I used to have a female guppy and platy, would he have a better chance at feeling if I put him in there? I have been putting mediaction in which works for fungus, finrot and to get rid of bacteria.

I will try and do a larger water change tonight.

I have just tested the water again and the results were (these are the only colours to compare.):

NO3:0.5
NO2:0.5
PH:6.5
KH:40
GH:180

The ammonia reading I cannot tell you because it is not included on the test strip. The only readings it gives are the ones I have given you in my last post.

 

[bmonki]

How long has your tank been set up? how did you cycle it? you need an ammonia test, go buy one.

 

[Fish Lover Forever]

It has been set up since 30/7/12. I followed the instructions from the place where I bought the fish and the tank (well most of the fish.) First I put the heater and thermometer in. Then I washed the gravel in hosepipe water very well. I spooned the gravel in the tank and spread it around where needed. Then I put a ocean rock in witch has some holes in so SOME of my fish can play in it. Then I put one or two plastic plants in. I used tap water and filled the tank, I left it for 3 days with the filter, pump and heater running. The temperature was right and everything was ok when I bought the fish. It is only recently in the past month I have been having these problems. The man in the lfs got one off the shelf and gave it to me, I did not know that I needed to get a seperate one! Actally my lfs is the ones that make these problems by not telling me the right things!! Oceon Commotion is the namee. They said I could have 10 fish in my tank then I come online and find out I can only have 8 from the fish forum!

 

[Man of fish]

First go out and buy a liquid test kit, such as the API liquid test. The strips are extremely inaccurate. Then postage results here. Next I'd plan on rehoming that Molly. They really need around 120-150 liters or so. Also, you did a "fish in cycle" and I'll bet money that you just recently replaced your filter cartridge? If so, you're right back where you started and there's nothing to process your fishes wastes.

Also, another thing to point out is that molly's are actually brackish fish by nature, and thrive much better if kept in brackish conditions

It doesn't sound as though your tank was ever cycled, so as Man of Fish said, you would really benefit from a liquid test kit so that you can keep an eye on the eater conditions. Ammonia and NitrIte should always be at 00 ppm. Nitrate should be a lot lower at about 10-20ppm. So you need to be doing daily water changes with dichlorinator until you bring everything down to save levels.

As others have said, your stocking is going to cause problems in the long term. A.) because of the number of fish you have in such a small tank, and b.) because of how incompatible some of them are (i.e. betta and guppies don't generally go well together because they are both fin nippers). My advice would be to do lots of research on each species of fish that you have, and then rethink your stocking based on the new advice/knowledge you gain. For example- keep the guppies and re-home the rest. Or keep the betta and re-home the others, and maybe get a group of pygmy corys or ammano shrimp
It's always very very important to do research online about fish before you by them- fish shops are notorious for giving bad/false advice to make money.

Agreed about the fish shops!!
