My Pacman could be in trouble!
I have only had Norman for 2 days and I think he might be in trouble. First day I got him home he ate 2 crickets and settled down in his moss. 2nd day he ate another cricket but decided to swallow some orchid bark at the same time. It was a fair sized chunk so today I removed him, cut the moss into small pieces and replaced the orchid bark with coconut fibre. I put him back in his home gave him a cricket and waxworm but he's ignoring them and has totally buried himself in moss. I will be gutted if I lose him so soon, he's a green horned.
10 gallon tank
80 degrees
80-85% humidity
trimmed live moss.
orchid bark now replaced with coconut fibre.
misting and water bowl/ spring water.
dusted crix and the occasional waxworm.
artificial plants.
3d back wall.
so from what i see you need to replace absolutely all moss with coconut fiber as i said earlier.
drop humidity a bit, you want 70-80 range.
temps - make sure it has night drop of a few degrees and feed him after the lights are off after he poops, right now you need to make sure he hasn't impacted due to him swallowing this bark piece. give it a few days and see how he looks, touch his sides for any hard lumps, but right now change substrate, fix temps, humidity and let him be, he needs to adjust to his new environment. if in a few days he seems to be interested in food and you don't see any impaction signs ( see his poop, he isn't bloated, etc) offer food.

oh i would switch his water dish to a bit smaller one for now, it seems too big for him or may be it is just pic
