Cute little buggers. You don't need UVB lighting, so I don't know if it's hard on them or not. I just run a red light (watts vary pending season) for basking which keeps the spot around 90 degrees while the rest of the viv varies from 72 on the bottom to 85 on top. I have 4 in the Exo Terra 36x18x36. You can put the blues in together with the other WTF, but I wouldn't put another one that size viv. These are big frogs and LOVE their space to move around in. You do need to quarantine them for a minimum of 30 days and get two clean fecals done to make sure the new isn't bringing any nasties into the communal viv.
