I do like the name Tourmaline for one of them.

They are eating kale dandelion greens and other veggies. The last owner fed them entirely on cat food, which makes them grow and breed faster but only results in a high protein roach suitable for whatever reptiles need that, but protein foods also make them stink. In the wild they would eat mostly vegetable matter.

They typicaly live 2-3 years. It usually takes about 6 months give or take to reach adult size, less time if they are in a warm and humid environment.
