i have a 90 gallon freshwater tank, with a bunch of different little fish in it. i want to convert it to a salt water tank, but i couldn't figure out what to do with the old fish. i was at a fish store, and they had a LARGE red oscar for cheap, so i bought it thinking it would gobble up all the other fish, solving my problem, and providing some entertainment in the mean time. so far, i dont think he's managed to catch any of the other fish! he chases them around, but doesn't seem to have the finishing move to catch them. any ideas on how i can help him out?
thanks
