Hi guys,
I keep my lateralis in a rubbermaid, bare bottom (no substrate). I stopped using a substrate for all my bugs, actually. There's no need for it, and it makes it soooo much easier to keep them extra clean and odor free.
I feed them a home made recipe for gut-loading, and plenty of leafy greens, prickly-pear cactus pads (a customer of mine grows them for his tortoises) and fruits. I keep them in the 80's.
They seem to be accepted by most of my geckos. They are FAST, though, and sometimes neonates have a tough time catching them. They can also exude a weird, sticky substance when handled.
Greg, if you need a starter colony, let me know.
