The Nassarius snail is a popular saltwater aquarium invertebrate that is prized for its scavenging abilities. These snails are native to the Indo-Pacific region and can be found in shallow waters along sandy bottoms.
 
Nassarius snails are generally small in size, with a shell length of around 1 inch. They are known for their unique spiral-shaped shells and a long, pointed siphon that they use to detect food and move around the tank.
 
To care for Nassarius snails in your aquarium, you'll need to provide a tank size of at least 10 gallons with a sandy substrate. These snails will burrow in the substrate to search for food, so it's important to avoid using a substrate that is too coarse or sharp. They are also sensitive to copper, so it's important to avoid any medications or additives that contain copper.
 
Nassarius snails are peaceful and generally not aggressive towards other fish or invertebrates in the tank. They are great scavengers and will eat leftover food, detritus, and other organic matter in the tank. You can also supplement their diet with sinking pellets or small pieces of shrimp or fish.
 
Maintaining water quality is important when keeping Nassarius snails in your tank. They prefer a salinity range of 1.023-1.026 and a temperature range of 72-78°F. You'll also need to provide good water flow in the tank, as these snails rely on water movement to help them detect food.
