Care

Bubble Snails are generally easy to care for in a well-established marine aquarium. They require stable water conditions and benefit from a varied diet that includes detritus, dead plant material, and meaty foods like frozen mysis shrimp. It's important to ensure that the aquarium does not have aggressive fish or invertebrates that may prey on these small snails. Additionally, a tight-fitting lid is recommended as they can be escape artists.

Reproduction

Reproduction in Micromelo undatus is not commonly observed in the home aquarium. In the wild, they are known to lay egg masses that hatch into free-swimming larvae. These larvae eventually settle and metamorphose into the adult form.

Habitat

Bubble Snails are found in shallow tropical waters, often in seagrass beds, mangroves, and coral reefs. They are benthic creatures, meaning they live on the bottom, where they forage for food. Their natural range includes the Indo-Pacific region, from the East African coast to the central Pacific islands.
