Ok its shed---- rinse w/ reg saline - they can swell etc --- your lighting is good -- but your going to need to invest in a bigger UVB fixture -- the 14" is too small for a bigger tank like even a 40 I recommend a bigger tank 120 gallon -- Pet Smart has started selling Zen Habitats they are a good habitat I have 2 of them you can make payments on them -- -- I recommend you get a 24" Zoo Med if you can find one--- that is a T5 and you will need to upgrade the bulb to a 22" Reptisun 10.0 T 5 - the UVB your using now needs to be inside the tank or NO screen its a 5.0 bulb and good for aquariums and not strong enough to go thru screen --- you want it w/ no obstruction and directly over the basking decor 6-8 inches for adequate UVB exposure -- you can also get a 24 watt Arcadia Pro T 5 w/ the 12% bulb for a 40 + gallon tank found at Pet Smart as well -https://www.petsmart.com/reptile/environmental-control-and-lighting/light-fixtures/arcadia-reptile-prot5-uv-b-kit-65058.html?cgid=500114&fmethod=Browse
