Going to be getting a shoal of rbps in soon. I'm thinking 6-8 all at 2". I've got a few tanks that I could grow them out in - gota couple of feeder tanks at 50gal, 20gal and 100gal. Also got a 200gal that i was thinking they could grow into, would that be an appropriate size for a shoal this big with adult rbps? also what filtration am i looking at?
