Red and white brittle starfish

[Leon821019218]

Was cleaning the glass and when I flipped my algae scraper I saw this little guy crawling around on it. It looks kinda cool, never saw it before but is it safe? I read that some could get pretty big and may even be a hazard to your fish when they grow up. So leave it in or remove from the tank?

If I remember correctly, the only harmful, fish-eating brittle stars are the large "green" brittle stars, that one is most likely Harmless, (@ISpeakForTheSeas if you have anything else to add that would be appreciated)

The green serpent stars are the fish eaters. Pretty much all brittle stars are considered reef safe.

Yeah, pretty much all serpent/brittle stars (Ophiuroids) found in the hobby are harmless/beneficial CUC - as mentioned, the exception is the Green Serpent Star, Ophiarachna incrassata, which is abnormally opportunistically predatory.
