Hi. I have two PAnda Mollies and this one has looked scaly and sick for at least 6 months! He's pretty aggressive (always has been) he's over a year old. He was about the same size as he is right now when I got him and his movement hasn't changed at all. Is this something that happens to mean fish? Ha! Seriously can anyone guess what's wrong with him? All my levels are great at the moment, I have not had any die-off's recently (except a snail that committed suicide). I have lots of fish (about 30 in all, Platty's, Mollies, Guppies, Gourami, Cory's, Plecos, one snail, neon tetras and Zebras) in a 30 gal tank, and many fry. All swimming happy and well fed, its just this guy that looks terrible.
