if this is the wrong place, sorry... didn't think it went under fish...? seems like all our plants have come with bonus snails....while I don't like it. I keep buying them. we have gotten rid of most of them and let a few live in the guppy tank for algae reasons ( its the only tank that doesn't have an algae eater). is there any way to know what kind these are? the eggs were orange and some have black shells and some are more whitish-- could be the same just younger.
