Hello I got a 1 year old bearded dragon with the set up from a friend who could no longer care for her properly. There is a zoomed tube fixture with reflector and a brand new reptisun 10 t8 bulb. Should this be mounted inside the tank or on top of the metal screen pictured below?
if it does need to be mounted inside is it okay to turn it sideways so I can mount against the back wall or does it need to hang from above ? I would just replace the bulb but I can’t find a t5 in 18”. Thanks for the help ?
