I don't have too many full shots of my tanks, but here's what my leos are living in right now. I use washed and sanitized PLAY SAND as a substrate. I've found it's much more reliable then calci-sand, and I've never had a problem with it. I do intend on replacing it with sand-grain tile when I get the money.

Also, the hide on the far RIGHT has been replaced with a clear deli container as a nesting spot for Cheerio, who is now gravid!
