Interested in Tiny Filter Feeders

[Tennyson]

Lately I've been interested in getting small little filter feeding things. They all seem like they need a little bit more care than normal filter feeders like a feather duster.

The ones I'm interested are:
-Cluster Duster
-Christmas Tree Worm
-Coral Hermit Crab

Are any of these species impossible to keep or don't last more than a month or two?

Cluster Duster
My invert book says that they do not survive well in aquariums unless collected with hard substrate and maintained without predatory fishes or serpent stars.

So is it saying that serpent stars will eat them? And what are the consequences if they aren't collected with a hard substrate? Will they fall apart?

And I imagine they need more food than your average feather duster right?

Christmas Tree Worm
Do these last long in an aquarium if there are normal feedings of baby fozen brine shrimp and phytoplankton? And will the coral they live on survive well? I have seen one in my lfs, but it only had maybe 3 of the christmas tree worms, will they multiply?

Coral Hermit Crab
I have never seen these guys in person, but one person here had one with a christmas tree worm rock. Is there any place they can be bought? Same care and hardiness as christmas tree worm or feather duster?

Thanks, sorry for the long thread

Christmas Tree Worms need to be in a small tank with lots of feed. I know one guy here had a really nice 2 gallon with christmas tree worms.

Not many people checking out this forum. Is there another forum I could post in?
