Betta Fish: Pray for my boy and his appalling taste in ladies

So my boy pancake has been acting a bit weird in the last couple of days. Trying to fling himself out of the tank, spending half of the day in places he can see his reflection. When I first caught him, I put a bubbler in the corner so he can no longer get in there and covered the relevant walls of the aquarium with clingfilm so he can’t see his reflection anymore. There is a lid on the tank. The water parameters are all fine.
He’s been making bubble nests. The first one was a decent attempt. The second, not so much…. (See the picture).

The objects of his lust have been a burrito and a Pepsi max can 🤦🏻‍♀️. Send prayers for my idiot son.
