I have an 85 gallon tank (dimensions= 72"Lx15"Wx18"H) with two Penguin 350s running on it. I am going to be getting another (probably canister) filter that will sit under the tank and run along side the penguins. Plus I do a weekly 50% water change. I someday want to switch from my current stock and have a tank with just oscars (and maybe my favorite JD). I will be buying Juveniles so I want as many as possible. Obviously when they are bigger I can't have as many but I want to get a bunch of them for starters and pick my favorites then donate the rest to my lfs or sell them. Any suggestions of oscar color variations? once again I want to get many of them for starter then get rid of the ones I don't like as much.
