Hi, I'm new to the group today and new to fish in general. While
cleaning my 20gal tank, I was rinsing the filter in a bowl and there
are two teeny tiny little swimmers in there about the size of an 1/8
inch piece of cut thread. Can they be babies? I have two gold minnows,
one silver minnow and six danios. I haven't seen any eggs anywhere or
any odd behavior. What are these little swimmers?
