View Full Version : Do I want these guys in my display tank?

These guys live in my refugium with the chaeto. Are they likely to cause damage in my display tank? It's that sea star looking thing crawling on the glass.

Looks like mini brittle stars. Very harmless and awesome at cleaning up detritus. Breeds readily in the tank by splitting.

Not quite sure on it's size(hard to tell from pic), but its either a brittle star(very small like the size of a quarter) or serpent star(can get very large). Both are beneficial, but the latter when bigger can grab smaller fish for dinner.
