All the other fish look ok, including the other wolf (erythrinus Sp. Tahuayo). My sick wolf ( erythrinus Sp. Peru) will swim around and then go back down to the corner but bumps into the glass before stopping. I don't think he can see very well...if at all. I'm going to get some pimafix tomorrow, but I dosed the tank with 2500 mg of Amoxicillin after doing a 50% water change and will do it 2 more times every other day. My ConJag had duck lips a few weeks ago and the antibiotics really worked well and he is completely recovered. I just dont know why my Tahuayo has fungus. I must have introduced it somehow...I mean that is the only way it could have gotten it right? From another sick fish. Either that or my Jag tried to lock lips and swallowed its face. The Jag is a female and is at the 8 inch mark. She has been pretty mellow with all the other fish, but I have noticed her seem more agitated and aggressive in the last few days. I have had Red Devils in the past that after hitting a certain size, they literally will turn into killers overnight. I mean no problems at all, and then like a switch...they start killing everything in the tank. I've never fully grown out a Jag, so I'm wondering if this happens with them as well. In which case, I may need to start looking for a new place for her to live.
