one of my fish it seems that his eyes are poping out of its head it some thing kinda new it only had it for a few days and its scales are turning a dark black if any one has heard of this b4 let me know wats going on
Start doing daily 25% or a little higher water changes and a medicine of your choice from the lfs, he/she has got popeye. For the black scales perhaps ammonia burn.
I believe its called Maracyn 2 or you can use Melafix, those are the two i have used for other reasons in the past. Im sure there are plenty of other brands out that will work for you if you cant get these.
