Note to self: avoid flurry clownfish...
My Valentini Puffer loves to knock snails and conch on their back. I havn't seem him try and eat them in most cases but its annoying to have to go on re-flip mode several times a week.
Haha, my Valentini does that too. He goes around and flips the snails upside down all the time. He even pushes them all to the corner of the tank.
