Sorry i find it funny when people say their frog will be fine in a 12'' cube because its "arboreal" lol . How much space does an aboreal frog use in the wild? Just because they are aboreal doesnt mean they will not or do not climb. It would be like taking you and putting you in a space the size of small restroom and saying you will live and reproduce just fine. Not trying to rain on your parade just want to point it out. Frogs will live for years and reproduce in a glass box if housed properly. I have a friend that her oldest pair will be 15 years out of water this year. I use empty film cans for breeding my imitators not bromilead. The problem i have found with bromilead is they do not always hold water like they should and if you have to take out the brom to remove a tad it is a challange. The empty film canisters will always hold water and are the perfect size for them. Good luck.
