That would work for froglets but is too small for adults in my opinion. They are quite a bit bigger than red eyes and very active at night. I currently have mine in a 24 x 18 x 24 Exo and I feel that it is too small, I am having a new 45 x 17 x 24 Protean terrarium built for them. If you want to stick with Exo Terra the 36 x 18 x 24 should give you enough room for a small group.
