I know that hard corals are made out of polyp colonies together in a limestone skeleton, so for hard corals, I woud really be speaking for polyps, but are corals considered invertebrates?

Any living marine or freshwater animal without a vertebrate is an invert, including corals. Strangly enough, things like the tunicates (sea squirts) have a primitive spinal cord during their life, thus are vertebrate animals like we are. Both of us are in the phylum Chordata.

It seems that people while stocking a SW always speak of "Stocking their tank with corals and other invertebrates." So I never thought of them as invertebrates.
Thx for replying.

pretty much by inverts we mean turbo snails, hermit crabs, shrimp, etc.
