Somehow my 8 mo old mimic got the netting off of the powerhead and was in to his eyeballs when i found him. I got the powerhead apart and carefully unwound each of the three legs that were sucked in from the impeller. They look pretty mangled. Its been 3 days now and hes still alive. I can see the pain in his eyes. Ive taken everything that can stress him out or harm him from the tank..is there anything else i can do..ie..water temp..any additives..what can i do to help him heal?
