Hi guy, I have a bunch of these things growing in my tank. I think they are snails but I am not sure. They are very small, less thank 1mm in size, and doesn't seem to be growing much bigger. The shells are flat like half of a mussel shell. What are they and how do I get rid of them?
The tank I have now is holding 3 guppies, 6 baby guppies, and about 50 RCS.
I change water every week using tap water and Prime.
