1. Size of enclosure - approximately 18x9x12
2. # of inhabitants - specifically other frogs and size differences 2 FBs, think 1 male and 1 female. Female is noticably larger and fatter

5. Water - type - for both misting and soaking dish - use room temp water after sitting out 24-48 hrs

7. Enclosure set up i.e. plants (live or artificial), wood, bark and other materials. - had live plants for the first month - they died and I have not replaced. I also think the frogs may have been eating them? or just destroying them from chasing each other. Have a large plastic rock with lots of hiding places and climbability
