Okayyyyy then we dont need a reflector and distance should be about right --- so I would increase the amount your feeding unless hes not eating anymore - feed him as many bugs as he will eat in a 10-15 minute time frame and add more salad material ----- like turnip greens mustard greens and collards - different squash like yellow or butternut --- here is a website you can go off to get more ideas to feed him

I am gonna post some websites for you to get him other worms to feed him that will give him variety
BSFL - these are a staple feeder and they dont need to be dusted w/ calcium
https://symtonbsf.com/ order large as they are small
http://www.mulberryfarms.com/
http://www.dubiaroaches.com --- they carry horn worms butter worms -- the horn worms are a
hydrating worm and they grow really fast so order small amount - the butter worms are a good worm just dont over do it
http://www.rainbowmealworms.com -- I have been getting silk worms from here they are spendy and hard to find but another good staple worm
http://www.abdragons.com
then you can always get super worms from petco or petsmart but then again you can always order from these places I gave you --- I would mix it up for him and watch his weight and growth
