Does your UVB have a reflector in the fixture? If not I recommend you get one- your rays are going all over the tank and you want them directed downward toward him Search results for: 'reflectors--'
this is going to benefit him
Please get a solid bright white basking bulb like this --- you need a digital probe thermometer when getting this you want temps 95-100 F -- Exo Terra Sun Glo Tight Beam Basking Spot Lamp
the heat emitter does not produce the UV he needs and is good for night time temps- if your tank is dropping below 65 F at night then you want to use the heat emitter I would move it to the top of the tank center - heat emitters should not be used for basking bulbs - you want a bulb that mimics the sun - this is a good reason why your having the shedding issues along w/ him sleeping alot -- the basking temps is what starts digestion and the UVB is what helps w / the calcium process -- what is the bulb your using for the UVB ? is it a 12% bulb ? this bulb requires certain distance and its good its in the tank --
