redfoot hatchling shell

[oscar]

peanut is about three months old and the back of his shell above his tail is curving in. Being my first hatchling I don't know if this is normal ? and if not would like to know what could cause this.

How humid are you keeping him?? What are the details of your set up?

I have him in a ten gallon tank, sphagnum moss substrate, ceramic flower pot cut in half for hide, under tank heater controlled with a reostat so temp of glass above hide 80. most all of tank top is covered with a CHE with a johnson control A419 so inside temp. is set for 80 to84 degrees. I have an indoor and outdoor thermometer sensor over the hide and keep the humidity between 78 to 85.
