Abalones are the only one you listed that are not filter feeders (they're grazers, much like snails). The remaining three are filter feeders and usually do not have good survival rates in reef tanks. I'd avoid them completely.
I didn't see it on your list and definately wouldn't recommend it without knowing your system first. But, the family of giant clams do well in alot of people's systems if cared for correctly. This includes Maximas, Deresas, Gigas and Croceas.
Also, large featherdusters do well if cared for properly.
I responded to the other thread first:
Hi,
Abalones aren't filter feeders, but substrate grazers. There are a couple oysters in the genus Crassostrea that are captively raised for food, but I think they are all temperate water species. There may be some tropical species, but none that I've ever seen offered for sale. Flame scallops and mussels are offered for sale regularly, but are difficult to keep alive in aquaria for a long time. They need an almost constant supply of phytoplankton to sustain them. Rob Toonen wrote an interesting article about green lipped mussels for www.advancedaquarist.com
I had an oyster on a mushroom rock that did well for a year or so. I gave that rock to UnderGrad I believe, so I don't know what has happened to it.
