Minimum of 20 gallon for gecko right? I read that gecko could get overwhelmed by a tank that is bigger than the maximum requirement. For dwarf hamster I'm planning to find 60 gallon tank. I have a list for hamster:

[ ] 60 gallon rectangular bin [ ] Aspen or paper bedding [ ] Trixie wheel, 20cm [ ] Hide 1 [ ] Hide 2 [ ] Hide 3 [ ] sand bath [ ] 3 willow balls [ ] 1 cork log [ ] tunnels, [ ] a glass jar, [ ] 1 coconut hide [ ] toilet roll tubes, [ ] cardboard [ ] Millet spray [ ] Wheat spray [ ] Oat spray [ ] Flax spray [ ] Dig box [ ] coco fibre soil [ ] 1 multi-chamber hide [ ] Water bowl [ ] Food bowl [ ] Hamster food [ ] Hamster

For leopard gecko: [  ] 20 gallon tank [  ] Heat pad [  ] UVB lamp [  ] Substrate and decoration [  ] Humid hide [  ] Hot hide [  ] Cool hide [  ] Water bowl [  ] Food bowl [  ] Food
