Where is the best place to get bristle worms fire worms, and other small sand dwellers? My sand needs to come alive with creatures. I purchased a detrivore package online about 3 weeks ago. That was expensive and 3 weeks later I have no sign of any of the worms or Amphipods. I'm thinking - these are worms and bugs for @#$% sake - It shouldn't cost me 80 bucks for a handful of worms! Seems like a lot of people somehow get these things naturally in their reefs but I am not sure how.
