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?
