I understand and can appreciate the lineage thing, but at the same time those corals came from the ocean, so many other corals, likely from the same parent colonies will also come from the ocean. Just because it didn't come from Y's tank, that doesn't mean it couldn't be from the same natural colony. I have a few LE's, so i certainly appreciate the names, but it is more a guarantee of what it could look like. Most things (esp acros) cahnge color depending on the conditions provided. That can make it difficult to make a determination on wheher ornot the coral is what someone says it is. I bought a Marshall Island purple bonsai that is identical to the garf purple bonsai. I lost the MI bonsai in AEFW treatments, but I can compare skeleton from the MI to my garf PB's, and they are seemingly identical (as was the color). I wouldn't have sold the MI's as garf PB's, but I had no problem with it being called a purple bonsai. The burden of hype issue where someone posts some green zoas and says they are PPE's on ebay (seen it numerous times in the past) lays on the shoulder of the person buying. It may be unethical to sell something as something it is not, but people make a lot of money at it, so they will continue to do it. The person buying should really know what they are getting instead of buying something because it has a catchy name they've heard around. I laugh when i see something called something it is not, but ultimately, the buyer is responsible for knowing what they are getting.
I guess I'm torn. I don't mind the use of common descriptors for description. It lets me say, 'Hey, I may want to look at that'. If I lile, I may drop the money on it, even if it's not what it says it is. Until there is an organization that registers and documents the different corals and their origins (like the AKC or CKC in the dog world), you can only go on the word of the seller that it has the lineage. I've got a ton of zoas that look exactly like many of the zoas on Zoaid, but I know for a fact that they didn't come from the person who named them. I still like being able to use that descriptor as a way of telling someone what I have. Of course, I don't make money off of selling things at higher prices (the demand in my area wouldn't allow selling higher priced corals based on names and I try to trade for things instead), so that changes the way I feel about the topic. I'm prone to buy something more because of liking it's appearance than for a name (maybe because I know the name doesn't do me much good in my area). If it's a blue danae with red polyps, but doesn't have the lineage of a SM monti, but I like the look and am willing to pay the asking price, I'm likely going to get it. If I sold it, I would sell it is a SM 'lookalike', unless I knew it had the lineage, though (therein lay the ethics of the seller). When you're talking a 1/2" frag for $80, something can usually be called a 'lookalike' (and explicitely state no lineage to the LE originator) and sell for ~$55-65, so either way it's going to cost you. I see both sides. I guess I just kinda straddle the line. If you tell me it is an LE, I'd expect it to be, but can't call you out on it unless I can effectively play seven degrees of Steve Tyree
