One of the reasons I got them (well was going for one
) was because I know they can withstand aggression (can be aggressive) and would need to be, being in the tank with the vieja & texas (who whilst now are placid, wont always be that way). But as they were so cheap, I got a few, I can keep the nicest and sell on the rest as/if and when I need to. I just like geophagus species, very personable fish Ive found.
