What percentage of UVB is it and how tall is the tank? If its a 12% you could probably mount it inside but if its a 14% and the tank is only 18" tall then it would be too much.

Of course the bigger minimum would be better but a 75 gallon does work. 40's, 50's and 55's are too small for sub-adult and adult beardies.
