I bought my oscar about 2 years ago, and was about 4", a year later i was moving and gave the oscar to my wife's grandpa. Anyways, i was looking at the oscar the other day and seen a nice big hold in the middle of his head, the oscar is now about 11-12", i heard mixed suggestions and assumptions, i took the oscar back, put him in a tank with an other oscar, JP, and red devil, never experienced an oscar w/hole in the head disease. can somebody give me a little advise please. . . . . . thanks
