I think a pack man frog will fit your bill.

The babies only need a critter carrier for the first 7 or so months and then a 12X12X 18 is more than big enough for them.
Just need to keep 80 to 84F during the day and 74 to 76F at night and if you get a albino no lights needed just ambient room light is
good.
No UV light needed as they stay buried most of the time.
just feed crickets and night crawler pieces with a dusting schedule ( one of the mods has a great schedule) I am sure one of them will post a link.
The babies need feeding daily until they get about 2 in STV then you can feed every other day and the older adults 2 years and older can go longer
2 days or so. And don't be surprised if they don't eat for a week every so often.

My Pepito will be 3 years old this may. and I love him to pieces. He is my avatar pic.
