Epic fail on my part. I put the babies in a breeder net attached to the side of the tank with suction cups. I put a little bit of sand in the bottom of the net to keep the adults from trying to pick at the babies. I guess the sand was too heavy, as the breeder net was on the bottom of the tank this morning when I came downstairs. Maybe the babies were savvy enough to hide in the rocks, but I have my doubts.
