Does a Betta fish hibernate

Answer 1

No, I have had my male betta fish for 3 years, and not once has he gone into hibernation. Good Luck!
My Beta has been inactive and not feeding for at least a week. He lies at the bottom of the bowl, nearly sideways, apparently sleeping. I haven't tried heating the water yet.

Here are two sites answering that question. Both agree that water temperature may be the issue.
