:help: My spotted groupers front fins look as though another fish might be nipping at them. Is this a common disease; or one of my other fish ? also has changed in color over the last couple of days from the white to a gray or blackish :help:
Its hard to say without more info. What does the tear look like? Did it happen suddenly, or over time? What other fish do you have in your tank? Have you noticed any aggression?
