While I had it in a catch container I got curious and threw in a small nasaruis snail. The worm (Booger is his name) slowly and lazily hunted the worm. seems that the mucus on Booger is quite toxic. every time the worm would touch the snail it would spasm and loose some functionality, 3-4 hits and the snail was very disoriented and laying on its back not moving much, Booger crept right up and covered it. Within an hour all that was left was an empty shell!
Now about a week later Booger is out on the hunt again He is completely ignoring the small astrea snails I have in there for him and is looking for the small nassarius snails.
Pics will be posted shortly
