i use bed a beast and i like it a lot for the frog enclosure. a 10 gallon would be ok for one frog, maybe two if they are babies if you turn in so that it is oriented vertically. they are arboreal, so height is much more important that floorspace. i keep my frog in a room that is heated with a space heater, so i don't actually use any other heat elements for her. the frog enclosure is the farthest away from the heater though, so it isn't quite as warm in that corner of the room. it is always slightly warmer at the top of the aquarium during the day because i do use a flourescent bulb for lighting for the plants, but it really only raises the temp at the very top a few degrees and it is slightly cooler in the room at night also. probably 76-77 at night and 77-79 during the day, with the very top of the aquarium 80-82 because of the light. nolvasan is great stuff and i like that it has pretty much no smell at all so i don't have to worry that my frog is absorbing any harmful fumes after i clean.
