Hi,

I'm the proud owner of two albino walking catfish (Clarias Batrachus). One of them has been ill for the last four days and I can't identify what the problem is or how to treat it. The fish has lost weight, and stays at the top of the tank in a corner breathing with it's lungs. When it does swim, it does so listlessly and keeps banging into objects. My other catfish is fine as are the other fish in my tank. I've been checking my tank parameters and they are all normal: ammonia 0, nitrate 0.25, nitrite 5, pH 7.8. The tank is maintained at a temperature of approximately 26 degrees Celsius (79 degrees Farenheit). My aquarium is a 135 liter tank (35 gallons). I have treated the tank twice with approximately 10 ml of Rid-All General Aid. I'm unable to identify what disease the fish has so I'm not able decide what method of treatment to follow. Somebody, please help.

It sounds like you are way overstocked for a 35 gal tank. Your nitrites are up for an established tank. I would suggest daily water changes of at least 20%. I had walking catfish back in the 1970's and had to keep only 2 in a 70 gal tank they have a heavy bioload as well as your 2 carp. A RTS gets up to 6" and needs at least a 55 gal. Please look into stocking for a 35 gal tank.
