The Bubble Snail(Bulla Occiddentalis) is a great snail to have for freshening up your sand/mud bed. These snails are omnivores and will hunt tiny organisms like some worms and tiny mollusks. They will also eat cyano and diatoms. They are primarily a nocturnal snail. They will be seen climbing rocks and glass at different times of the day. They are reef safe and a unique addition to your aquarium. Right now we have some babies freshly hatched from our breeders. They are not very big right now, but can grow to about an inch long.
