Well the little RD is about 2.5 inches. I have several growout tanks currently that are 75 and 90g tanks that he could potentially live in. When I get my 500g up a lot of the fish will be moved to that. The tank that I would likely put him in has a couple 7-8in Syns, a 7in Severum, some Oscars and GTs in the 3-4in range, a 4in Carpintus, a 3in Paratilapia, and a few 2-3 inch Thoricthys and Cryptoheros sp. He would be one of the smallest fish in the tank... Think I should risk it and pick him up? Do you think he is a nice RD/Midevil specimen?
