Query: Too small...

I don't know about newts, et al. but I would assume it is the same for them. I do know that this habitat is far too small for a hermit crab. It may serve as an isolation 'tat or a travel tank but it would be inhumane to keep an animal in such a small space indefinitely.Specifically for hermies, they are social animals and really should have at least two friends to live a happy existence. This 'tat is too small for even one, let alone three.
