a few ciclids, corys, yoyo loaches, plecs, 4 silver sharks
I know a little over stocked but I do a water change every week, and a big one at that cause the oscars are mucky fish.
I have 2 internal filters running to help with the clean up.
I keep having to re-plant my plants but they don't seem to like the taste of alot of them so they just uproot them and then spit them out. Silly fish. Have actually seen the white oscar pick up a plant and replant it elsewhere if he/she didn't like it where it was. Ok I have an oscar that doesn't worry my other fish and is a keen gardener. Woohoo aint I the lucky one.
I would like to mention off topic though that if anyone is thinking about keeping oscars don't go down the same road as me as oscars DO NOT make good community fish, I have been lucky with this one, it is afraid of the smaller fish.
