This is a pack deal that will come in a pack of  100. This is good for cleanup crew and to feed fish such as puffer fish.
Collonista amakusaensis, often mistaken for baby turbo snails, are some of the best grazers, feeding on algae, diatoms, and even species of Cyanobacteria! This species stays very small and reproduces in captivity easily. They come in several colors ranging from brown, tan, white and even pink! 
They grow no bigger than 1/4” so they are perfect for those tiny hard to reach spaces!
These are completely reef safe but have been known to reproduce so much they can clog skimmers and pumps. So be vigilant in checking equipment and you will enjoy them as much as we do!
