Snails

[Vet Lady]

Please help. I recently added several zebra snails to my reef aquarium but they won’t stay inside the tank. They crawl on top of my equipment, down the outside of the glass and even down the cabinet. I’ve managed to spot most of them before they died. Is this typical behavior from this type of snail and is there anything I can do

What?!?!? I have never heard of this at all... I don't know how to stop this other then getting a lid.
