Hello,
That stool looks relatively normal, but a little dry perhaps. Can you review his diet & eating
regime a little bit? Does he eat greens or much vegetation?
I would try getting some fluids into him, using either a plastic dropper or syringe. Drip some onto
his snout to see if he will lick some water off of his nose that way.
We would be happy to review your tank setup with you as well, if you would like.
