yeah, pass on the sand sifter, and get a chocolate chip! just kidding. Yeah I agree with monkeyfish on seastars being immortal. I lived in Belize for 6 years and go diving in the barrier reef all the time, residents on the beach would pick up palm size seastars and throw them around to get them out of the way. The government was not smart enough about the creature and sent a team to molest them in the 70's to "control their population" and the result is a doubling of the stars. Anyways, I always thought it's funny that people are so careful with not having stars expose to air or they'll die, because we do that all the time picking them up and throw them around and they still thrive and breed like weed down in the Carribbean. My point is, they are really tough and isn't all that difficult to keep unless something is seriously wrong with your water.
