I've only kept D. galeatus, but yes, I've bred D. tessellatus. I set pairs up in 15-quart boxes in a rack system. There is a 1/2" layer of Jurassic Sand, catch basins on the warm and cool end, and a nestbox with a coconut fiber/sand mix. I mist the enclosure several times a week and cool the geckos down for six to eight weeks. They are actually quite hardy.
