Back in the 80's, Moorish Idols were all the rage...... Surprised there's any left after the hub-bub over them back then. The price they commanded was outragous, a couple of hundred bucks if I remember correctly, probably the only reason EVERYONE didn't have one.
The debate about leaving delicate species in the ocean is a interesting one!
When I got back in the hobby this time, I decided I wouldn't purchase anything that was not tank bred, or tank raised. I figure over the past 20 years, I've done my share of taking from the ocean, as that was your only option back in those days.
I remember the days when a few sprigs of limp Xenia and a feather duster or two constituted a successful reef tank. Flash back 20 years and if we just left everything in the ocean that didn't do well, then none of us would be in the reefing hobby right now. <u>I HAVE A FIRM BELIEF IN ECOLOGY</u>, and will not knowingly purchase a wild caught fish again, but for a reefer to make a broad a statement such as "leave delicate species in the ocean" is to be somewhat hypocritical, as we all stand on the shoulders of hobbist before us who advanced us to where we are now........ (and the dead fish, we all stand on a big huge pile of dead fish, Let's not forget).
I think we can moderate better what is taken from the ocean by gaining a better understanding of the animal's needs. Advanced fish need an advanced aquarist with a proper system to care for it.
In National Geographic</em> , I once saw pics of Phillippinos eating these beautiful reef fish, and thought "I could enjoy that fish in my tank for years, but as a meal, it wont last them a day." (If they used it in some asian dish, they'll just big hungry again an hour later).
