American eel hibernating for the winter

[Passionfish]

So, about a week ago, my American eel started becoming less active. I was just starting to get worried, and remembered that he has to hibernate during the winter. I feel like a fool lol. No, but seriously if I'm wrong please tell me what's wrong with him. I'm pretty sure it's him hibernating, but I'm not 100% sure.
