Hello! So I have hornwort, water wisteria and java moss in both my 5.5 gallon tanks. I have malaysian trumpet snails in both, but apparently a breed of snails that I did not want got it and are reproducing. I can identify their egg clusters and remove them from the hornwort(which they are using to reproduce). And I am killing them on sight as well, but what I want to know is, what is an effective way of dealing with them without harming the MTS or the bettas, or the plants?
