How long have you had that oscar for?? It looks like hes got the beginings of HIHD, or at least hes got some kinda strange coloring, looks good tho, is that an Arowana in the background??
Ohh and i love your signature because i had an arowana for about 3 weeks till one day i came home, and it had knocked the glass off my tank and i found it on the living room floor.... so sad!! It was an amazing fish and i wish i could get another one, only problem is my 55gal tank max (damn parents).
