Need help. Bearded dragon tail and body turned dark brown.

[Hayleyh098]

Hi! I have a 3 year old rescue bearded dragon that we have had for about 4 months. Recently we upgraded to a 75 gallon tank and upgraded lighting, UVB, everything. Over the last few days, he has turned a dark brown color and his tail has turned noticeably darker as well. He also has constant stress marks on his stomach and darker beard. He’s normally a really vibrant orange color so it’s very obvious to me that something is wrong. He has reptisun T8 17 watt UVB placed 11 inches above basking spot, 150 watt basking, and normal household 40 watt bulb for his cool spot. His basking temp is around 100 and the cook side stays around 75-80. His appetite seems very normal. He gets 5-10 dubia roaches per day and kale, book Choy, and butternut squash daily. I’m not sure what’s going on with him and it’s making me sad bc I’m not sure what to do. He also occasionally closes one eye which I have read is an indicator of something wrong. Here is a pic of his body and tail.

The other pics are him normally.
Any help would be greatly appreciated!!

The T 8 is too far away for distance they need to be unobstructed NO clear plastic cover over the bulb and it should be 6-8 inches directly above the basking decor---- I recommend you upgrade your fixture to a 24" Zoo Med Sunblaster or Arcadia w/ either a Arcadia 12% bulb or a Reptisun 10.0 T 5 -- that is better suited for a large tank than the T 8 ---- please do this ASAP--- the color change is him going into shed on the tail ---
