Sand sifting starfish lost an arm!

[wuteva]

I noticed the blue legged hermits eating one of his arms 2 days after we brought it home...acclimation seeemd fine, star still seems healthy, moving around, etc. Is this a forward to his imminent death, or will the arm grow back, and will the blue legs leave it alone?

If the hermit crabs leave it alone, it might recover, at least for a while. These animals seem to starve to death in tanks, after they strip the sand of animals.

Hermit crabs are unpredictable, but they're likely to leave the starfish alone.
