I purchased a new baby gtp alittle over a week ago. Currently I have him in a 15 gallon terrarium with bio balls and water seperated by a barrier underneath coconut husk substrate. Two times now at night I have found him on the ground with a mouth full of the substrate. I've taken him out and washed it out of his mount. The inside of its mouth appears to be health and it has eaten sense I have bought it. During the day he is perched and appears to be in health condition. If anyone has ome suggestions or device it would be greatly appreciated.
