I think it takes a lot of effort to get a glass tank to be suitable for a BRB, especially a neonate. I have mine in a 15 gal tank, with heat tape under 1/2. I have a hide box on each end, hot and cool. The hot side temp is 80-87, the cool side is 70-75. Humidity is 60-80% all around.
The yougsters spend 75% of there time in the cooler area.
My adult seems less fussy?
