This guy is fairly flat, when you make him mad or flip him over, he kind of folds up like a Taco. When he is happy, he runs around my Zoa's like a snail with no shell. He has some super long antennae. Should he go back in the tank?
Stomatella smail. Or skull cap snail. Beneficial grazer. I have hundreds in my tnak. They surge and wane in numbers relative to the amount of algae and starfish in the tank.
