I have an opportunity to get some unsexed juvies of these guys. Never kept them. Has anyone kept them before or have any info about them? I know they get to 7-8" range. In nature, they travel behind sandsifters and eat what they put into the water column. The tank they could go in would be a 114g tank (5 ft). They is a trio of phenos I'm growing out, 1 albino taiwan reef male, and 1 Copadichromis melas male in there.
