Toby,
A circular tank with a moderately conical bottom is optimum for growouts, flat bottoms are still more than adequate.
Ditto. I was reading either in one of my aquaculture books or an online comment from Dr. Timmons, one of the leading authorities on RAS culture, that a conical tank bottom is over rated. Additionally I'm not sure it would be the best thing for my fry sized bluegills (Although i could be wrong). They seem to prefer to lay on the bottom when not feeding in my tank, especially during the night. I can't see them being able to do that in a tank with a conical bottom.
