Carpets are semi arboreal.. Not going to be very happy in a rack tub. Especially as a baby. I know people do it, but in my opinion its not much different than making tree pythons be in a tub with nothing to climb on. My boy was wrapping around the cage latch making it impossible to open the door without pinching him. The moment I put perches and a ledge in there he was happy and stopped constantly trying to find ways out.
