oscar

Hi All, I finally have the space for a big tank and am going to have one custom made in the coming weeks...very exciting stuff! Still planning out the design for the equipment, sump and cabinetry, but thought I'd get some advice now on stocking it to make sure I'm heading in the right...

I have 4 cichlids in a 90 gallon tank with plenty of space and caves/hide holes. 3 of them get along and one is a total jerk. He is picking on one that is injured (I bought him that way) and I noticed a piece of fin missing on my albino oscar. I am not sure what else to do. I keep catching g him...
