Well, I think I've read of those garras being a bit obnoxious in small numbers. I hoped it wasn't your species with enough room. Not what you've found out. I'm happy they're working as individuals, they are pretty fish! But you know I'm a hoplo fan & hope the big guy isn't a pest too often to them...Shouldn't the hoplos grow too large eventually for a pesty garra to bother? I dunno, I haven't kept either...but I have a crush on hoplos as you may remember
