He would not fit in a 10gallon tank thats for sure damn sure....and actually the shed that he did once I moved him into this new cage was his first complete shed with nothing retained that`s why I`m not sure if he`s too stressed about the cage..I think it has more to do with all the noises in the room ( it used to be quiet and now I have my T.v. and my computer setup in the same room)
