Are there any reef safe starfish?

[High tide]

Most brittle and serpent stars are reef safe and extremely hardy(stay away from the green brittle star, it can eat fish). The white sand star(Archaster typicus) is also quite hardy and long lived, provided a large enough sand bed is given and regular feeding of fish. Proceed with caution in regards to Linkia and Fromia species, although reef safe, they are sensitive to water chemistry fluctuations, are often mishandled, poorly shipped, and usually starve over time in our aquariums. That being said, many people have enjoyed success with them. Picking healthy and well acclimated stars will reduce heartache and TAKE YOUR TIME when introducing them. A good rule of thumb is to not buy anything you haven't read about, if it's foreign to you...don't buy it!
