Hello,
Ok, so it just suddenly came up. Could he have gotten bitten by a cricket possibly?
At least it isn't getting bigger at the moment.
So the
UVB light is a compact/coil type of bulb? If so, you will need to change to a long,
fluorescent tube bulb, such as the Reptisun 10 or the Arcadia D3 12% or 14% tube. The
UVB exposure is much better than the compact/coil lights are.
Let us know how things are going. I hope it doesn't get any larger.
