I have a little 1 1/2" Albino Oscar that I picked up from Wal-mart cause they had him in a tank with some larger Africans, he looked healthy but his fins were getting fairly tattered. So I felt sorry for him and brought him home. I put the little guy into my 10 gal with a few of my guppies. After a couple days he was swimming around happy, not shy anymore, chasing the guppies and eating anything I put in the tank. Already it looks like his fins are healing up nicely, but also they are getting a dark tint to them, what is this?
