I have a Russian tortoise that I think might be trying to go into hibernation. He is staying in his tunnel more than he usually does. I am not sure if him going into hibernation is a very good idea because recently he has had a parasite in him (Which I can't remember the name of right now) and I don't want him going into hibernation unless he is healthy. I did notice recently that the temperature was cooler than normal so I bumped it up to a 150 watt basking bulb instead of a 100 watt basking bulb. Does anyone have any ideas on what I should do?
