Getting worried need some advice

[mgigy]

I have had my beardie for about 10 months. Adopted him when he was already 18 inches long, maybe 2-3 yrs old. He lives in a 120 gallon aquarium set up as follows:
Exo terra solar glo 160 on one side with a branch he can sit on up to about 6" from the bulb.
Repti Glo 10.0 UVB over the other half of the tank.
100-105 daytime temp under the solar glo.
75-80 temp under the repti glo.
Washed playsand substrate.
My concern is that he's never been a good eater.
Does not touch fruits or veggies.
Mainly eats mealworms and gut loaded crickets, but not many. Maybe 10-20 a week.
He does drink water when I spray and bathe him.
He has not been losing noticeable weight though.
Has been pooping about once every 2 weeks or so.
Now he's had a black beard for 4 days straight and has not eaten.
He has been pooping more often but they are small and a bit yellow and runny.
Any ideas?
Any ideas?

Is it time for a new UVB bulb?

Have you taken him to the vet and had a fecal sample/test done? I'd start there!!!

How long have you had your beardie under the Solar Glo MVB? With that being 160 watts... the safe minimum distance should be around 18" from the bulb to your beardie.
Having two sources of UVB is not really neccessary. One UVB is all your beardie really needs.
There have been some issues with the Solar Glo MVB's as of late and the ReptiGlo UVB's are questionable as well.
How old are the UVB's? As mentioned above... it may be time to get a new one.
Right now the best UVB on the market is the ReptiSUN 10 fluorescent "TUBE". They can be hard to find locally sometimes, but are fairly reasonable here www.petmountain.com
How are you measuring the temps in your beardie's enclosure? digital thermometer w/ wire and probe, stick-on type, temp gun?
Do you supplement with calcium and a multivitamin? If so, how often?
Also as mentioned... a fecal test might be a good idea, just to rule out any parasite problems.
