Betta Hurt Fin

So, somehow my clumsy betta got stuck in between the little gaps of his sponge filter. He kind of cornered himself. Once I noticed, I quickly helped him get out.
Well now he isnt really moving one of his fins. I know he will have to rest it since he most likely hurt it. He is only using one fin as of now & is opening his gills in and out a lot. He's fin besides that.
Will he be okay?

 

Maybe get something for him to rest on near the top, so he can breathe.

 

Reduce the water level so he doesn't have to swim very high to reach the surface for air, so he can rest and heal. Basically, bring the water level down so low that all he has to do is poke his head up to take a breath. You might have to move him into a temporary container for that, like some tupperware. This way he can rest on the bottom and still reach the top for air. If you have some indian almond leaf, throw that in there with him. You know how when you have a sick day you stay in bed to get better? An indian almond leaf and a low water level will let him do the same.

 

What i'd do is get the betta one of those suction cup leaf beds(on amazon) and some bettafix to treat his fin wound.

 

Thank you guys! Hes up and swimming all over now. We have a floating log and he was in there resting for a bit and shortly he started swimming more and more.

 

He was just spooked it sounds like. Glad he's feeling better.

 

You did not need to use bettafix for the fin wound?

 

He didnt have a wound, he just didnt move his left fin. I thought he maybe hurt it, He rested some and then started slowly swimming more and more.

 

Oh ok. Glad he's better.
