In addition to this topic, of Assassin snails, which at the Aquarium Club meeting I was listening to a group of seasoned hobbyists which speculated the ability of a neurotoxin from the snails. Whereas, for instance why would a huge snail like a Mystery snail get taken out by one... little, tiny Assassin?
So one possible rumor of their abilities. Which also makes me concerned about putting my hand in a tank with them, lol or not lol - not sure.
It was, what seemed as I had walked up to the group of people talking, that someone else in the aquarium field had proposed this consideration. Referring to "he" , as I missed the name. After listening to the back and forth for a few minutes, I was distracted by someone else and went off in the other direction, without further details. Though they had mentioned there were types of Mollusks (Conus parius SW
cone snail for one), which have special abilities for capturing /eating their prey.
Might need to check on this.
edit - not the Assassin snail but just a little bit
