My Betta's left fin looks smaller and has a split in it, I think he hit it on his little cave when I put him in his gallon tank while doing his partial water change. (For now I'll just put one of his plants in his holding tank, I have to put something in with him or he gets stressed) Sometimes he doesn't move his left fin while still moving the right. Other then then that he still is his flaring perky piggy self. Do you think his little "hand" will mend?
