Ok so I am gonna say this the UVB is not strong enough -- here is some advice on what is recommended on this forum for UVB
Which
UVB light should I use?
The best
UVB light is a ReptiSun 10.0 fluorescent tube HO (Or Arcardia 12% in the UK). Compact or coil bulbs do not emit the proper amount of
UVB light for a bearded dragon, and should not be used. Other brands, such as the Zilla Desert Series and ReptiGlo have been known to cause eye problems and other health issues with bearded dragons, and should be avoided. The reason that some UVB lights (Zilla, ReptiGlo, coils/compacts, ect.) are considered dangerous is because the wavelength of UVB that they emit is shorter and more intense than the wavelength of the "safe" lights (ReptiSun, Arcadia). UVB lights should be replaced every 6 months. The T5’s are a strong bulb and only need to be replaced once a year – the T 8 every 6 months--- where as the T 8 are not as strong—they need to be placed inside the tank the T 5 10.0 bulb approx 10-11 inches from basking spot – the T 8 approx 8-10 inches from basking spot—the cover needs to be off the bulb for full effect of the UVB rays-- I would get this changed out ASAP--- here is a website for nutrition
http://www.beautifuldragons.com/Nutrition.html-- get your UVB changed out and start again w/ the BSFL --- why isnt it you cant get crickets or dubias ? Are you in a apt -- ? His eating has alot to do w/ the lighting in the tank -- please check out the nutrition website it will give you other ideas of what to feed him -- he does need the protein ----
