Hello, I have recently purchased a 100-130 gallon tank, i know all about the nitrogen cycle. I have talked to my LFS which the guy who runs it is also a good friend. I have one cascade 1500 canister and one wet/dry filter and a bio wheel 450 on stand by. Of course i want a dynamic duo of oscars (males), some bloody parrots, and a salfin pleco. I already have a baby green terror. I talked to severel LfS about overstocking my tank but all of them believe including a neighbor with 2 450 gallon tanks that i could have 1 green terror, 2 oscars 1 male red 1 male albino tiger, a pleco, and some bloody parrots maybe 2?. I would also like one other south america cichlid. i was looking at a red texas but there related to flower horns so that could turn out deadly. Please help!!!!! I use to have a 3 gallon and 15 gallon tank so this is a big stepup but i also know alot about fish, my family use to have a 600 gallon tank.
