So you can id them from the vents? That is great I'll try to get some close shots tonight so you can perhaps ID them for me.
^ very cool, any success breeding them?
i don't know much about these fish but feeding in general. You should try introducing these foods free-float along with the frag, and take the frag out sooner and sooner each day during feedings until it's completely gone. then just feed the foods in the water column.
