I picked up a Trio A. Bicoloratum slings about 6 weeks ago. I got them all eating. They all molted once and then I put them all in modified Bata fish cups. They all dug right away, to the bottum and closed themselves in. 1 molted w in a couple days. One after a week. But all three have been closed up for roughly 3 weeks. How long should I leave them alone?
