So I through in a heater, just an AC20 I had. Overkill for the tank but it's been very reliable for me. Looks ugly though.
Bobby the Betta has perked up and is more active but only when he wants to be. He may not have a lot longer as a few people told me that it it's getting lethargic, that's an age thing. I do wonder if I throw in a guppy if he would be happier chasing that around. I know it's cruel to the guppy though. He perks up when I am around for awhile but just is lazy. The heater makes him swim faster, not more often. I am not concerned, I was just hoping heat was the issue.
