Hi Becky, thanks for your response. Actually I've been surprised about how non-violent they all are. They sometimes sleep nose-to-butt in a line in their favorite places (corner, large bromeliad leaf), and I have never seen one attack another or act afraid of another. It's a 20-gallon right now, but as they get bigger I'll need to decide whether to break them up or get a very large enclosure. They seem to seek each others' company, with the brave four sleeping in one spot and the laggers-behind hiding in the same bromeliad leaf or pip.

But here's my happy update: within 2 hours of making my post here, both Pretty Boy and Tiny were out and about-- and in places I could corner them! I was relentless. I held that cricket in front of Tiny, and he scrunched up his little face as if it it were an old smelly shoe. But I pushed and tickled his lips with it until FINALLY he ate it! Encouraged, I did the same for Pretty Boy-- and he ate as well.

Whew!!! Apparently posting here was all I needed to do. I guess it embarrassed them, lol!
