Which species are only available wild caught?

[t1a1c1h]

We are trying to have an ethical reef tank with only caprice bred fish and corals. So far all our corals are frags from captive grown colonies. Are there any species which cannot be grown in captivity or fragged? I'm thinking scolys, trachy and lobophyllia are only wild caught? Are there any others?

I believe even they can be cut and over time regrown into 2. Not cost effective though.

Elegance corals, fungia, and quite a few others. They can be fragged, but like moat said it's really not cost effective and they take forever to grow back.
