    Recently my baby albino oscar cichlid died due to a disease where his scales and fins fell off. Which I found strange because none of the bigger fishes had that  problem. Now very small black worms have appeared all over the tank starting in the filter. I have no idea what this is or if it is hazardous to the fishes health. If anyone can let me know what it is or what I should do that would be awesome. Thank you.  ??? ??? ???  :'(

    Could you tell us what your water parameters are please? Ammonia, Nitrites, Nitrates, PH.
    Anytime you lose a fish you need to do a large water change, So that would be the first thing to do.
    Let us know

    This is kinda weird...

    I was queuing at my LFS the other day and the guy in front of me asked the clerk about the EXACT same thing.
    He did have a solution for it, but I wasn't really paying attention.
    I'll ask about it when I go there next, probably won't be til tomorrow though

    Since we didn't get any answers as to water parameters i can only guess at the problem. And I would guess at a water quality issue, especially if the scales and fins fell off while in the tank.

    Just been to the LFS to get ideas for my 50 gall...

    The clerk said that he had a similar problem a while back. The way he solved it was to cut back on the amount he was feeding his fish until the worms died off
    They never cam back

    I think a good vacuum and filter case rinse (in tank water of course ;) ) would help also.
