Hi guys I’m Nate this is my first time doing a salt water reef tank . I got two clawing fish a few weeks ago and so far so good . One of my fish has a white spot I ask my LFS about this and showed him some pictures he said it was fluke and gave my some prazipro to treat it . So I treaded twice already looks to be gone away . So after it goes away what should I do . Oh yea the spot is by his mouth .
