You can put silver dollars in your tank as they're just calcium carbonate skeleton just like aragonite sand. Unfortunately they usually become festooned with rather ugly algaes after a few weeks/months and look unsightly thereafter...

Thanks for the link! I think I really like that!
Would any of the clean-up crew eat the algae off of the sand dolllars?
