    Hey guys

    I've got a nano tank (50x42x42) that I set up about 3 months ago. Here is a pic up to now:

    I added 2 ocellaris clowns about 1 month ago, and very recently added a royal gramma (1-2weeks ago) and a yellow watchman goby (3 days ago). I came home was shocked to see that my royal grammas tail fin has been knawed on. Like most of it is gone (the top half) to the bone. My ocellaris are perfect, they have no signs of injury or eating etc. Since I added my yellow watchman goby I haven't seen it. But I read that is probably due to hiding initially. But now I'm really concerned that theres something in my tank eating trying feed on my fish :/

    Here's a list of my lifestock:

    2 Ocellaris black clowns
    1 Royal Gramma
    1 Yellow watchman goby

    4 scarlet hermit crabs (smallish ones)
    2 Sexy Anemone shrimp (who have been munching on my plate coral!!)

    My theory is either there is something in my rocks I don't know about, or either the hermits or sexy anemone shrimp are eating my royal gramma while it sleeps (the anemone shrimp have been eating at my corals :/ )? Alternatively maybe its some kind of fin rot. All my parameters are perfect though, and everything is thriving so far ... (thank God ).

    I really don't know what to do? Any advise on how to deal with this would be greatly appreciated...

    Thanks

    -Daniel

    P.S. on a general note I've moved the plate coral to the sand incase anyone is concerned about that...
