Tubs if you are breeding large amount and separate racks for the babies. So yea Josh you are right and how many geckos you have will determine and I would op for a rack system if you got a bitThis will probably largely depend on what kind of setup you're going to have. I would imagine most large volume breeders opt for tubs. Correct me if I'm wrong, experts!
AgreedPlastic definately... I like the shoebox size for hatchlings. But I keep my adults in tanks.
