so I have this iridescent shark of about 4 inches. it has come down with a relly bad mouth fungus or cut on its nose, maybe it bashed its nose open then got the infection, i have it it a 16 gallon quarantine tnak where i am medicating it, it keeps getting worse, its all red and fungusy and its to the point where it looks like its eyes is going to come out, the fungus has destroyed so much tissue, i was thinking of just waiting out and hoping it will get better, it just lays on the bottom of the tank now, do you thinkit can recover form this? should i euthanize it? shold i keep trying and wait till it dies?
