Sand dollar info.

That's a hard question to answer. Factors like age of sand, depth of sand, etc play a huge roll in things. However, I haven't really seen very much information on long term survivability of any of the sand sifting animals. Aside from the one poster who has had his for 2 years, I haven't heard/read/seen anyone else with one that has lasted more than 1.

The sand is half new and half a couple of years old (mixed old sand with new when we started up our 230g) and is about 2 inches deep. There seems to be lots of worms etc. in it for one to eat. Thanks for the info it's good to know.
