Some say bumble bee snails may eat them but best way I can see from others who had many is manual removal with thin nose pliers or tweezers grabbing at base and removing all the tube or little bit of glue over the opening g
Went to my lfs last night and got some bumblebee snails and went through and crushed all of the ones I could see and scrapped the rocks to try and pull the snails out. My hermits got a nice snack and hopefully the bumblebee snails will hunt out the ones I can’t see and eat any potential babies.
