I actually have a number of vermetid snails developing in my tank now, about 7 total that I have spotted and removed. I have a 1" Green Spotted Puffer that I want to train to eat the vermetid snails, but I haven't had a lot of opportunity yet. I know that the puffer has the capacity to hunt and kill the snails, but I need to train the puffer to identify the white vermetid shell/tube with the scent of food. That's the tricky part. If anyone has any ideas I'm all ears.
It's actually kind of funny though, when I crushed the vermetid snails with metal tongs, the ghost shrimp ran over to gobble up the snail's remains. Ghost/grass shrimp are one of my favorite tank inhabitants.

the ones o have have a purple red ish tube. All the “tubes” I have that are white are small feather dusters. I have both, the tubes look similar but the feather dusters are white. Snails are the purple reddish color.
