Firstly, hello. My name is Dave, and me and my wife have kept Tropical fish now for about 3 months.

Usually we ask for advice at Pets at Home, but even the so called experts don't seem to know what's wrong with our fish. Myself and my wife have been reading this forum and it seems to be full of people who know an awful lot about fish, so we're hoping someone will be able to help us.

In my wifes 60L tank (Zebra Danios, White Cloud Minows, Neon Tetras, Panda and Bronze Cories), we noticed that one of her Zebra Danios had inflamed gills and was rubbing itself on the gravel. Pets at home were useless, so we decided to treat that fish with salt in a seperate aquarium. It's been in the hospital tank now for a day and hasn't made much (if any) improvment.

What worried me more tonight, is I have noticed one of my Panda Cories doing the same thing in my seprate 60L (Guppies and Panda Cories) tank. It's gills are also inflamed, so I assume it has the same parasite as the Danio. We do share nets, and gravel hoovers between our tanks, so perhaps that's how the parasite spread. Whilst I'm typing this I'm watching one of the Guppies that shares the aquarium with my Pandas is showing similar symptions, and a few of the Guppies have inflamed gills.

We don't know an awful lot about fish just yet, but we do know that my wifes Neon Tetras will not like salt, so we can't treat her aquarium like I have done with my tank.

I lost a female Guppy tonight, however she did not have inflamed gills, nor did we see her rubbing against the gravel or objects. She does, or did, have a rather large belly after giving birth recently, so I think she may of had a swimbladder infection, but I can't be sure about that.

I will try and take some photos, but fish are incredibly hard to capture in a photograph.

So, can anyone advise us as to what parasite our fish may have?

Later edit: We think the poor water quality due to overstock was the problem. In one of the 60l we have 6 zebra danios, 6 minnows, 10 neons, 2 bronze cories, 4 panda cories. We've done a 50% water change tonight and hope to see some improvement by tomorrow. We are also considering rehoming some of the fish. We'll keep all the cories, but we're wondering which of the rest of the fish would be best to stay.
 
Hi Dave.

The first thought that crossed my mind, particularly given the short time that your tank has been set up, is a reaction to Ammonia in the water. Can you tell us more about your tank size, stocking levels, filtration, the process that you followed when you first set the tank up, and ongoing maintenance (e.g. water changes etc).

Cheers
 
Red inflamed gills poor water quality, gill flukes, to bacterial.
But with the fish rubbing sounding like poor water quality to gill flukes.
Need to look at your water stats in ammonia,nitrite,nitrate,and ph.

Sorry didn't see the edit at the bottom.
Water change and take a sample of your water to the lfs and tell them to write the readings down for you.
 
Just seen you edit, posted at the same time as my reply. That's where I was leading... Regular (and frequent) water changes to keep Ammonia and Nitrite dissolved (as you've have already done), plus see if you can get hold of some established filter media from a reputable fish shop to put in your filter to give it a head start.
 
If the tanks been set up three months the tank should be cycled.
Need to look how many fish are in that 12 gallons tank, as if it overstocked that would account for the bad water quality.
How often do you maintain the tank.
 
Both tanks are 60L, L: 23 inches, W: 11.5 inches, H: 14 inches.

In one of them, we had 6 zebras and 6 minnows with the 2 bronze, then added 4 pandas, and 4 weeks ago added the 10 neons. We wanted to keep the neons in another tank, but then changed our mind and they ended up in this tank.

This tank has gravel and quite a lot of plants in it. Water quality is usually very good, but really got out of the control now. Temperature is usually 27 C. We do weekly water changes (sometimes even more if needed).

The two bronze laid eggs quite often, which made us think the water is very good.

Last week one of the neons had a swimbladder infection and was moved to the hospital tank and treated. Not even a week later we noticed one of the zebras having an unusual behavior. Also, one of the other zebras has a lighter coloured area on her right side, but people at the petshop didn't notice it.

That's how much I can say, more details from my husband tomorrow. Thanks for your reply.
 
The tanks way overstocked then.
Immediate water change, get water tested at the lfs.
You will have to get the other tank going or you will lose the lot to ammonia and nitrite poisoning.
Just take a mature sponge from the tank and add it to the filter in the other tank.
 
Could it have possibly been dropsy? This is when the fish suffers from internal swelling due to a bacterial infection and the gills often become red inflamed and the fish resembles a pine cone. I think it can be treated however the sick fish should be removed from the tank asap.
 
Would that tank be ok with 6 zebras, 6 minnows and 6 corrys?

Both tanks are matured, but the second one has 4 pandas and guppies in it. Both tanks show the same symptoms. How would you explain that, considering the second one is not overstocked and matured? We were thinking maybe there was something wrong with the tap water when we've done the water change this week.
 
Same symtoms as in red inflamed gills.
How many guppys in the other tank.
 
Guppies we have 3 males, 3 females and 15 babies (most of which will not stay in that tank).
 
There both overstocked then.
Till you sort your stocking out the fish will be ill through bad water quality.
Get both tanks tested at the lfs.
Go from there.
Invest in a master liquid test kit of your own.
 
We do have a master kit and we used it tonight when noticed the bad water quality.

We are probably going to sort something out for the neons tomorrow , but do you think the tank will be alright after that?

Also, how many guppies could we have?

Thanks for you help.
 
With guppys you need more females to males, as males chase them none stop.
See if the lfs will take the fry then that tank should be fine.
I would rehome the danio's as the tank not big enough for them as they are very active fish.
