My sister recently started cycling an aquarium for a betta fish. She bought some plants from our LPS and the next day we noticed about four very tiny snails. The tanks numbers are good so I think they will be ok. Today, we noticed what looks like two groups of eggs. But they look very different. One is a cluster of brown eggs on the gravel. The other are clearish and under a leaf. Does anyone know what kind of snail these could be from?
