one morning i woke up and saw that it had a black line going from it's middle down to the bottom, kind of like it was bleeding (but just discoloration there was nothing ON the skin). Then i noticed a small bullet hole.. like it legit got shot and was bleeding haha.
the hole hasnt gotten bigger, hasnt multiplied. the fish is swimming as usual (not erratically), and its eating my Formula 1 pellets.
what's wrong with it?? is it contagious??
