someone ordered me a basket star instead of a feather star, and i THOUGHT their care was pretty much the same as feather stars, but it snatched a full krill i had put in for the hermits to eat, and seems to be gnawing on it! do they eat/feed off of large things? seeing it with the krill makes me worry that it might even catch live little fish! i want, and plan, once my other problem is solved, on having a tank full of little gobies and such, so i don’t want something ELSE snatching up all my fish!

Do feather stars/crinoids regenerate into multiple individuals when cut up/losing arms? I have a piece that was left over from a very healthy somewhat "long lived" star(at least in captivity--in the store over a year and continuing to grow)that someone was apparently very rough with when buying...I guess it's really only part of an arm, definitely not even part directly connected to the body. I found it rolled up and still sometimes slightly moving it's little prickles, so I brought it home and figured I'd see what happens. It's been like 4 or 5 days, and although it's stayed mostly rolled up the whole time, it seems to be very active with its little spikes and little suction legs now, almost constant gently rhythmically moving them, as if it was a healthy live animal. I did NOT think they could regenerate new bodies like some starfish can*. I was sure it was just going to dissolve, but I HALF expect it to grow into a whole animal now! --as you can probably tell from the length/width, and that it only has a single branch division, it's clearly only the end of an arm. I'd guess maybe just 1/4 of the length of an arm. *another question on the subject--chocolate chip stars, and similar "full bodied" starfish canNOT grow new arms/survive cutting, can they? Dealing with harlequin shrimp, I'm familiar with choc chip stars anatomy, and they're basically large hollow hard stars with some support structures, and filled with large gooey organs. Once opened in any way, they cannot seem to close off the gaping opening to the outside in any way, and their insides are basically loose to the world. They can't regrow, or even heal from cuttings, or breaks in the "armor", can they?
