Name:

Asterina Star Fish


Pest Type: Starfish


Scientific Name: Asterina spp.



Treatment: Harlequin Shrimp eat Asterina (as well as every other starfish), so use with caution. The easiest way to remove these pests is to simply pick them out

Identification: A small (under 1" across) off-white, light brown, or mottled starfish, with short, wide legs for its body size.

Prevention: Carefully examine any new piece of rock or coral before adding to your tank, and remove any unwanted pests.

This small star may be one of several species that hitchhikes into our tanks (Class: Astroidea). They are probably harmless algal grazers and detritivores, however, they should be watched carefully as many starfish are coral predators. They may have as few as 2 to as many as 6 fully formed arms. They commonly emerge from shelter at night.
