Still appreciating all the responses. ^^
A note... i don't plan to separate the pair at all, and really hoping they'll do fine together. Ofcourse i see the risk in this...and that despite my effort to keep them calm and happy in their 140 gallon, he might still "dispose" of her after a breeding, or at any other time.
Im just gonna cross my fingers and hope that with a group of 6-10 individuals @ about 2-3 inches a pair will bond up nice and tight, and won't agress eachother too much. I mean the chances has got to be higher of achieving this when doing it like this, rather than buying two or more semi-adult fish and trying to get a pair of these?
