Fish Fanatic
I have had one Zebra Danio die and just have another that is sick too. The first one just developed this internal bump on its side. It got bigger and bigger until it burst out leaving wounds on the skin. It didnt appear to be an internal parasite, I presume it was some kind of internal growth. Needless to say the fish died a few days later. Now about 2 weeks later another zebra danio developed the same condition and it too has open wounds on its side now, though it is still feeding and quite active. One of my other Zebras has like a little blister/growth below his mouth it doesnt sem to do him any harm but it sometimes bursts then grows again. Anyone any ideas? None of the rest of my fish are affected
