My little reddy, a red betta fish hasn't been eating as much, looks to me like he can't see his food when I feed him because he comes out to get it but he can't catch it. Also, when he swims or sleeps he only uses one side of his body, is like he is having problems using the other side of his body. I know he is getting old in fish years he is almost 3 years old but, is ther anything I can do? I don't want him to suffer but I don't know how much I can do to help him either. Any advise would be appreciatte it.
Thanks
