As I understand it, there are hundreds of sediment dwelling worms that are very grain-size specific with regards to their preferred environment. One example is Rhepoxynius abronius. Although this amphipod is limited to the west coast of North America, I don't see any reason why there wouldn't be similar type organisms living in the more tropical type areas that our corals come from.
If these type of organisms live only in specific size sand sediment, I can't see them existing at all in live rock, no matter the quality. Even though live rock can appear to make a dsb "live", I think that there is room for improvement with regards to diversity. Mitch

That is why when a reefer wants to seed his tank it is a good idea to borrow some sand from an existing system.

Even grabbing some grunge from the bottom of an LFS' live rock tank might not work, as you may get some undesirable flatworm or aptasia populations. Inland Aquatics cultures this stuff, and I haven't found any Canadian supplier that does the same. Mitch

sandbed flora and fauna
if it's diversity you're looking for you should really go to your local saltwater stores and ask them to give you a bit of their sands every once in a while. they have all those corals and things that come to them every so often from everywhere that their tanks and sandbeds are probably full of diverse lifeforms.

Hi Ken,
To give you an idea how specific some of the sand requirements are, the amphipod that I mentioned before requires a grain particle size of 0.113 mm. Not 0.110 mm, not 0.115 mm, but 0.113 mm. Unless a local saltwater store has a dsb with varying sand grain sizes and zero sand sifting creatures, I doubt that they will have some of the animals that I am looking for. What I am looking for is a source where I can obtain more sand bed animals that would typically not be found on live rock.  Thanks, Mitch

There's nothing on that site that you can't get from another reefer - all of those organisms I have in my tank. As for the "assorted amphipods, copepods, etc", you're not really getting any of the specific burrowing detrivores per se. You could just be getting whatever zooplankton is crawling about their holding tanks.
I'm sure lots of people use these detrivore packages, but it seems that it's nothing that you couldn't carefully introduce (so as not to introduce pests) from any other local source.

Tony and Shrimpchips,
Yeah, that's why I was wondering if anybody had ordered from them. They have been in business for quite a while and are still selling the detrivore kits. I was wondering if people were happy with what they received. There's also Indo Pacific Sea Farms in Hawaii. http://www.ipsf.com/ They have sediment beds that are constantly exposed to open reef waters. Mitch

I also think you are bang on here (see bolded), but the critters listed in the link you provided are not the critters you are referring to as sand-dwelling critters for your DSB. I like your thought process, but you're not finding what you're looking for in the link you provided.
