As the topic states I have a 55 gallon tank that measures 48' x 12 wide x 20.5 high and a 400 emporer filter. Wanted 2 oscar but i guess the bioload of them is a little high for this size of tank. If i cant get 2 oscars what suggestions do you have for fish to inhabit this tank? I was thinking about maybe one Oscar and maybe a jd and some other scholling fish like some silver dollars or something. Any suggestions would be greatly appreciated thanks guys.
