Hi everyone.
I have two newly acquired RETF's, {one female, one male...}
The smaller, and presumably the male, seems to have some sort of infection on his mouth. It looks like part of a tongue was pushing the right side of his jaw. It's pinkish and the under the nostril is a small black patch...but it's not raised or bumpy.
It almost looks like a birth mark or tatoo.

It was fine last night, and I just noticed it now at 3:00PM
Any help would be appreciated.

I've had plent of reptiles and exotics in the past as well as now, along with these two..and never had this problem.

Here are two quick pictures I took to get posted.
The second is slightly blurred, but it makes it point.

The enclosure is a 20g tank, with live plants, 5-6 different types...
two mosses
and cocunut husk chips spread over liberally to keep huimidity

Thank you all.
