For some reason unknown, my stonecat madtom catfish is dying. He's about 4" long and as of yesterday was eating and seemed to be fine. Now he's pale and mottled, almost not breathing and from time to time his body is wracked with contortions as he takes a massive gulp. My water parameters are all great. 0 ammonia, 0 nitrites, Ph and water alkalinity/neutrality is perfect, nitrates are well below the 20 PPM safe levels and have done regular weekly partial water changes with the native water he came from. Any ideas what might have caused his demise? All of the other fish I have are perfectly fine with no signs of illness, parasites or disease. Saddened to lose him as I caught him myself and really liked this little catfish.
