Hi, well i have a 55 gallon with oscars, convicts,jds, and red eared slider water turtles (2-4 inch, don't worry they were raised with fish n won't eat them). I want to get rid of the oscars (sell) b/c they are getting too big. What fish would you recommend for a 55 with my current stocking except for the oscars? Don't worry if they grow big because i will be upgrading just before Christmas.
