Ugh! I don't like those little snails. When I used to keep dwarf gouramies they overtook my tank.
But i learned my lesson. You always rinse your plants under tap watter first. Wash each frond by hand so you can feel for snails and their egg cases. They feel kind of like jelly, and they're clear so it's tricky to see. That's why you gotta look for them by hand. Anyway, they detach if you wash them, but you may have to scrape gently with your fingernails too.
I got all my Hornwort and looked at the tank the next day and there were three little itty bitty snails in my tank! They are so cute, and I don't have the heart to kill them. :) I hope Angel hasn't eaten them. LOL
