Picked up 3 of these little guys today (about 3" apiece). I've been meaning to get some for a while, the only thing stopping me was the fact that my 180 is probably just about comfortably stocked now and i didn't really want to over do it. Anyway, went to my LFS today for some bloodworm and there they were. I just had to get them. I've done some research on them before so i know that the water parameters are not critical, i know they're peaceful and that they can get big, i know they can be skittish and i know they are jumpers. Other than that is there anything else i need to know about these guys.
