Native Habitat and Species Information

Paper Bubble Shell native habitat, distribution, behavior & aquarium compatibility.

The Paper Bubble Shell resembles a snail at first glance with its tan mottled shell and very large mantle that can be withdrawn into the shell. However, this invertebrate is actually a Sea Slug, in a class called the Headshield Slugs, which have developed this hard shell on their back in which they use to bury themselves in the substrate. Paper Bubble Shell slugs are reef safe, and are an excellent addition to any saltwater reef or fish aquarium.

Aquarium Care

How to successfully keep Paper Bubble Shell in the home aquarium.

The Paper Bubble Shell is sought after in marine aquariums because it eats large amounts of algae and diatoms. A well-established marine aquarium with plenty of live rock and microalgae is a good environment for to house sea slugs. Nitrates should be kept at low levels and it should never be exposed to copper-based medications.

Unlike many other Sea Slugs the Paper Bubble Shell does not release toxins into the water when threatened, but instead uses its hardened shell as protection. Little is known about the reproduction habits of the Paper Bubble Shell, but they may reproduce in the marine aquarium given an adequate food source.
