10gal for 1 an 5gal for each extra... make sure that its a tall enclorure and they like the water so provide a larger water dish that needs to be changed at least every 2 days but its better to change it everyday... easy to care for very hardy frogs live around 3years... great starter frog.
I have a large exo terra for 2 of them to go into and I have moved my Whites into a larger viv so his tank mate can join him too
OMG the tank is massive - the frogs have arrived and they are sooo tiny - I am going to downsize them into a 12"x12"x12" exo terra and then use the large one for my geckos lol
the 12,12,12 is about 7gals which should only house 1 AGTF with 2 just make sure they both eat enough other then that they should be fine what are you housing your whites in?
My White's are in a large 2x3x2 glass aquarium. The are all only quite small still so I have some time to think about maybe upgrading should I need to. they get al ong just fine though and I do try to monitor their feeding as best I cna just in case. My AGTF's are literally not even an inch long yet so I have hopefully some time to decide which way to go!!
I know this is a bit late but the first "crawley critters" I ever was owned by were AGTFs. I think they're great though they are not cuddly or cooperative .I love listening to the frogs "barking " at night and occasionally during the days too. I feed mine 2 week old crickets ,little mealworms.and fruitflies.They LOVE fruit flies ! The fruitflies seem to entertain them too because they chase them around. I have 15 AGTFs.I keep them in a tank that is 24inches high x 18 inches deep x 30 inches wide. It has a screen lid that is hinged so that the entire top doesn't have to be removed to feed and clean,etc. There is a large pot of Pothos vining plant in there and the subsrtate is cypress mulch. I have 2 partially submersed water dishes in there with one being more shallow with 1/2 "of water for the small frogs and 1 1/2" for the adults. AGTFs DO NOT SWIM.They do however need to soak daily. My frogs are very happy together in this set up. I built it myself with sheets of plexiglas and aquarium sealant. My son made the lid from nylon sreening (like for the house door.) and 1 x 1s.
