Hey! So i am new poster here! But I introduced myself and my tortoise a few days back. Anyways Knuckles has been acting really strange lately. I took him out today for a soak and he stayed in his shell completely which he hasn't ever done before normally he sticks his head straight out. Also he hasn't been eating too much compared to usual.He looks normal and his breathing is normal. Maybe it is too cold for him? I am going to go get some stuff to help bring up the heat because thats what I think the issue may be but if you guys have any other ideas that would be great.
