An ExoTerra 18Lx18Wx24H will work for one, a 24in. cube will do for a couple or trio (if you plan to get more). These frogs require low humidity and good air circulation to avoid respiratory problems. Humidity between 40-50% will be OK. A day temperature between 80-85F with a basking spot of 95F will be required. It's difficult to predict what you will need without knowing type of enclosure and room temperature parameters. In case spraying is needed; use distilled water for spraying and it will not leave water marks (avoid spraying frog). Pretty much you will be setting an enclosure for a White's; just drier and with a basking spot as discussed previously.

The best set-up for them would be a cycled planted vivarium; but you already have frog in hand. My recommendation would be to set-up the frog in a hospital type enclosure for a 30 day quarantine period. A smaller enclosure with a silk branch and some branches, water dish and damp unprinted paper towels for substrate will work. During this period observe frog is eating well and get two fecals done two weeks apart.

In the meantime you can set-up the larger enclosure and let it cycle for 30 days or so. There is information on the vivarium section on how to do this.

For food feed gut loaded insects (carrots, lettuce, oatmeal) sized same as distance between frog's eyes. Also, follow dusting suggestions in here: http://www.frogforum.net/food-feeder...schedules.html . A small glass bowl around 2 in. in height will work fine to place feeders on and monitor if frog is eating

Next time recommend set-up enclosure first and then get the frog. It will make both yours and frog's life easier !
