Ninja Snail (Lithopoma phobium)
Also formerly known as Astraea phoebia and sometimes referred to as Astralium phoebium, the Ninja Snail is a hardy, peaceful algae grazer with a dark, stealthy shell that gives it its name. Native to Caribbean reefs, it actively feeds on algae and biofilm, helping keep rockwork and glass clean while adding subtle natural beauty to your tank. Thriving in established aquariums with stable water conditions and plenty of rock, Ninja Snails are a low-maintenance, eye-catching addition to reef and fish-only systems.

Added a Ninja Snail to my 20-gallon reef tank last month. It’s been active since day one, eating algae on the glass and rocks. The shell is dark and looks natural. No issues with other fish. Easy to care for and adds a nice touch to the tank.

I was skeptical about snails in a fish tank, but this one is calm and doesn’t bother my fish. It’s been cleaning the back wall for weeks now. A good low-maintenance addition.
