Brand new here, been keeping 3 garden snails for a month now with prior experience. Two of them, Quasar and Pulsar, are curious but never cause problems. Gravastar, however, has escaped FOUR times in one week. He's never attempted this prior. Their container doesn't have a proper lid so I've been using a pane of glass weighed down with rocks and a small gap for air, and somehow that didn't stop him. Finally caught him last night, body sticking out and literally lifting the lid with his shell. Three rocks weighing him down and this Houdini reincarnate still had the determination to make me spend hours panicking every other day.
Luckily I've been taping down the lid and that seems to contain him so that problem is solved. But is this normal??? I replace the food and mist daily, and I clean the tank weekly, so I'm pretty sure he's just doing it out of spite. But I just wanna know if snails usually escape so frequently or if I've been forgetting something.
TL;DR, I give regular care to my snails who are usually chill but one of them is still determined to get out. Is that normal snail behavior?
