 |  Brittle Star Lost a Leg....
And its still moving. Just wondering if when brittle stars lose their legs the lost limp keeps moving. It doesn't SEEM to be caused by the water current... but could. Its been over 24 hours and the little fingers on the underside are still moving... and when a shrimp attacks it, the entire limb worms around. I'm pretty new at saltwater and this is the first lost limb I've had! so exciting!! |

Starfish Regeneration
"...Among the amazing abilities of starfish is a remarkable talent for regeneration. A starfish that loses a ray can grow a whole new one, given time. Most species can only regenerate if the central part of the body is intact, but a few species can grow back even from a single ray. Those species, like Linckia, will regenerate several whole starfish from a single starfish that gets torn apart."
Can also grow back from a single leg!
"...Linckia regenerating five rays from a single surviving ray. Specimens like this are often called "comets"..."
May yours also!

interesting... That's what I'm hoping for. I searched a bit but couldn't find anything (or used the wrong search terms) is there any documentation on this happening to a brittle star?
On the flip side, I wonder what's wrong with my tank to make the brittle do that... the tank inhabitants include (but not limited to):
2 Bangaii cardinals, Firefish, Coral Beauty Angel, Royal Gramma, 2 Peppermint Shrimp, Rock Boring Sea Urchin, Brittle Star, a Bumble Bee Snail, a Hermit Crab and tons of tiny tiny white starfish and mini brittles. None of those would attack the Brittle (AFAIK). Next check is the water perimeters (will do it when i wake up in a few hours)
Oh yea, its a 55 FOW 90 lbs of LR | |

Ummm, don't know about why leg fell off. Have seen before when starfish dying and beginning to disintegrate.
Maybe trying to clone self? 
How about a tank pic post... | |

I had a brittle star years ago. It lost it's legs one at a time. I believe it was, that I needed to do a water change....or do them more often... | |

I've been doing water changes about 15% every 1.5-2 weeks. I actually did one two days and before doing it i tested the water.. everything tested "normal" except for nitrates which was up to about 20..
i'll take some pics when i get a chance | |
