My swords were looking great until ramshorn snails decided to munch on them. I have picked out a bunch and the assassins are helping. I want to get more swords but not until I handle the snails. Any idea on how to stop them? I cut back on feedings to slow down snail production. Now I read that if there’s not enough food for them then they will eat plants. I can’t win either way. Also, any good plants that snails don’t like?
