Mylo doesn't ask to come out, but he doesn't say no to it either. I just pop my hand inside the viv, make sure he sees it then carefully scoop him up. The look is kinna like "Well, if it makes mom happy..." :lol:
When I had Stubby in a 10g tank.. he sometimes climbed up the sides. He even fell asleep vertical one night.. like the beardies do sometimes. When he is in a 20g he does not do that. He was in a 20g as a baby.. and I just recently put him back in one a few days ago.
As for wanting to come out.. hes pretty chill and goes along with anything. If I pick him up.. hes like ok.. lets climb moms arm. If I set him down in the room.. hes like.. hmmm freedom.. and slowly pokes around.
