My theory is that his water's too dirty(The filter is too weak for his new tank so we have to clean more often) so he wants to stay dry. He also sleeps on the rock most of the day.
I worry too much tbh


On an unrelated note when he's scared(or maybe just on land not sure) his poo is a runny mud consistency but in water it always forms hard nuggets that over a few days fall apart into brown flower-things (probably because he mainly eats lettuce)
