i love your animal prints and dragon skull.
is your tank top also made of glass? is that a heat lamp with a regular bulb or ceramic heat emitter? i think u might just be warming the glass instead of the ambient air if it's just rest there tho.
i keep 2 of my BP's - Elphaba and Fiyero - in separate 18 gallon tanks myself with a screen top and heat lamp and undertank heater so i know the challenges of glass tank husbandry. i got them and the tanks when i thought i would stop at two BP's. i think i'll be switching to ceramic heat emitters on a lamp dimmer tho.
