Sounds like you got some baby snails. Have you introduced any new plants
into your tank lately?

Hello RAFP,

Could anyone please advise on these "bugs" that have
shown up in my tanks? They are about the size of a poppy
seed, shaped like a football, and they cruise about in an
upright position. They seem to be eating the leaves of
plants, leaves that are alive in the case of H. polysperma,
mostly dying leaves otherwise. There is a population
explosion...
How about getting rid of them. I tried CuSO4...
bad move...
