Sick betta with white film

[Kiwi03]

Ok but it dosent hang on the back. It's an in tank filter. Why would it be sucking my betta up?

What filter? You found him literally inside it and not stuck on it?

[Kiwi03]

Yes, he was inside the filter! It's a tetra whisper filter which is an in tank one geared towards aquariums 1-3 gallons.

Wow that's scary.. well apparently the current is too strong for him, so just add the prefilter sponge and he should be okay. He is acting okay after that?
