I have owned oscars in the past but they were large hand me downs from a friend that I agreed to take care of. They died a while back and I haven't had an aquarium for a hile now. I finally broke down and bought an aquarium and a couple small oscars. One of them, a tiger oscar, has started showing very wierd behavior. I remember from the ones I used to own that oscars are moody and seem to like sulking at teh bottom of the cage, unless of course they get hungry or see me. But this new one has started laying completely flat on the gravel. It's skin is gray and has little fluttery pieces coming from it. It's eye's are glazed over as well. I would think that this would be serious if the thought that it was shedding hadn't entered my mind first. The dull color and clouded eyes remind me of the snakes I own when they are about to shed. So please, if anyone has made it this far through my excessively long explanation, do I need to be concerned for my fish, or is it just getting bigger?
