We have a beta fish. We have had him for almost a year, in the same tank with nothing have changed. This morning when we got up he has a big scratch on his head. Anyone know how we can help it heal. This was my sons halloween gift last year and I think he will be crushed if he dies. Thanks for any help in advance
