Blisters

[ARCH3R]

The conditions for my BTS have stayed constant for years. I noticed two bulges on top of his tail recently, and not knowing how easily they would pop I gently pressed them and water trickled out.

Treatment- I'm already sanitizing his container and using chlorhexidine and antibiotic where the blisters were.

Future- This is my main concern, I've always had a humid hide for him because he seems to enjoy it. After he basks he goes in there and lucks rapidly taking in moisture. Do I get rid of it now that blisters have occured?
Also is there anything beyond sanitizing, antiseptic and antibiotic that you use?

It's odd to get blisters on the top of it's tail. What do you use for heating?

I use a combo of undertake and over head, but the overhead is more than 20 inches away from him (cage was originally for a carpet, but impulse bought him at a show)

I think it might be from condensation building at the roof of his humid hide. The hide is in there because he developed RI without it.

I only posted to see just how common they are, and if anyone takes additional steps to what I said.
