mussel shrimp

[duendecillo]

I found some little things in my tank, and I've done some research, and I think they are mussel shrimp.
Anyone has info on these things? can they do any harm?

Only thing I can find is that they are members of the Ostracoda family.

Have a look at this page - there are also links on there.

HTH, Eddie
