90% of wild caught host anemones die in aquariums within a few months, and that's only counting the ones that make to the retail store alive; I don't know what percentage die between collection and retail, but I bet it's very high. Also, every host anemone taken out of the ocean means a loss of clownfish habitat and almost always the death of the clowns that were living in the anemone, according to every published book I've seen on the subject. This, unfortunately, does mean that any purchase of a wild caught host anemone has a negative environmental impact. Even if you are one of the very few that can keep carpet anemones alive, buyng one means the store will order another, and so forth. Does that make it irresponsible? In my opinion, yep. Of course, we've all made irresponsible purchases in this hobby, so I'm not trying to slam anyone. For example, Ron Shimek has written exactly about this, but then he also writes about the S. haddoni anemone he keeps, and a book about keeping host anemones in general. So it's entirely a different question about what's "wrong" to buy or keep in aquariums, but when you look at the statistics it's really hard to support the idea of taking these animals from the wild. Tank bred E. quadricolor (BTA) are so successful that it seems crazy not to go that route.
