I just received a new yellow terribilis at about 3-4 months old. I picked the frog up on thurs. and i'm keeping it in a 190 oz. plastic tub w/ a coconut hut and leaf litter. I never really see the frog..it seems very shy and it's eating very little. I am keeping it in the tub to fatten him up and make sure it's doing well. I have a 65g which is well planted and loaded w springtails. Would the frog do better if i just turned it loose? I'm a bit concerned.
