a 210 is fine, most people get rid of their pbass before they reach that size, either out of bordum or they just want to start over. The only pbass I've ever had get HITH is ocellaris, the others like tems, orinos, monoculas, etc., never had a problem with them. I've seen monoculas bred in a 125 by red1, so a 210 is fine, if others chose to go bigger, then thats great, but your fine. It's mostly a braggin right of the "BIGGEST" tank.
