My son just got a Betta on Friday. He adores the fish. I looked at him this morning and he has this white "fuzz" all over him. It does not cover him completely but he has several spots of it. Plus, he is not swimming around like he normally does. He is just staying still with his tail fins down and his head up. Is there something that I should be doing to help him? Do you think he is sick? Thanks for any help that you can give me.
