Common name: Cake Nassa
General information
Nassarius Snails, specifically Nassarius arcularia, are a popular choice among reef aquarium hobbyists for their scavenging abilities. These small gastropods are known for their distinctive behavior of burrowing in the sand bed and emerging when they sense food in the water. They play a crucial role in the cleanup crew by consuming detritus, uneaten food, and decaying organic matter, thus helping to maintain water quality and reduce nutrient buildup.

Care
Nassarius arcularia are hardy and adaptable, making them suitable for both novice and experienced aquarists. They thrive in aquariums with a deep sand bed, which they use for burrowing and as a source of food. It's important to ensure that the tank has a sufficient amount of organic matter for them to feed on, but not so much that it compromises water quality. Overfeeding can lead to population booms, which may result in a lack of food and subsequent die-off.
Reproduction
In the home aquarium, Nassarius arcularia can reproduce if conditions are favorable. They lay eggs in capsules, which are often attached to the aquarium glass or other hard surfaces. The larvae, known as veligers, are planktonic and can be challenging to rear in captivity due to their specific feeding requirements.
Habitat
Nassarius arcularia is found in tropical marine environments, often in shallow waters with sandy substrates. They are distributed across the Indo-Pacific region. In the wild, they are commonly found at depths ranging from the intertidal zone to several meters below the surface.
