It's not a fair comprasion. Look at the differences between the industries. Dogs are mammals, corals are treated like plants, and fish are treated like food. We don't hold them to the same esteem.
How sad is that? Which of those examples is on the endangered species list?
It comes down 2 things
Volume & Survivability. A puppy mill is not a good place to buy puppies from, but a large LFS that gets in multiple shipments of 100s of corals a week isn't a bad fish store. (We make that judgment based on other things) The process of treating those pests is very different.
It should not be, you always correct the source of a problem, if the goal is to actually correct it. Changing the oil on your car will never fix a bad bearing.
Let me ask you this. If you were to buy a puppy and the breeder said "Oh I just found out it has worms. I know you want this puppy I'll hold it for you if you give me a non-refundable deposit and then you can pick it up in 6 weeks when it's cured and you won't have to worry about a thing." Would you do it?
I raised Scottish Terriers to help pay for college, as a breeder I paid for all shots and vet visits before any puppy left my care. It used to be standard prcatice.
But say you go to a LFS and they say "We just got in this new batch of acros in, shiny and new. If you want to give us a non-refundable deposit, and then you can come pick up your acro in 6 weeks after they are fully QT'd and treated." Would you do that? I sure know I wouldn't there is a very high chance I'll show up in 6 weeks and the coral will be dead or brown and I'll be out my deposit.
This is why I try to avoid buying corals from a LFS, that "boycott" you alluded to earlier. It is safer for my tank to avoid buying from places that may have an issue. This is probably also the reason I have never had to deal with AEFW.
I really wish there was a better system but as long we buy maricultured, and wild pieces and there isn't a easier way to treat for pests, it just isn't feasible. The system I outlined on the other page was something I have been kicking around for a long time, and how I would go about it if I ever started another shop up. For me as somebody who has lost corals to pests, as well as lived with pests. I would want to offer my customers the option of getting pest free corals but the only way I could make it work would be to charge a premium and it would really only appeal to a select few people.
If this was done, I would buy from you. As it is, knowing you have AEFW, I would never buy a coral from you. It isn't personal, you had some really great pieces in your tank that I wish I had, but the cost is just too high.
If you did the math of what it would cost me as a shop to hold a coral for 6 weeks, treat it, factor in the losses (both death and loss in value due to colour shifts) I would receive over that time frame into the price. The price tag for fully qt'd, pest free, colorful, wild pieces would be huge. If you had two identically pieces. One 100% guarantee no pests the other. No gaurtnee (but that doesn't mean there is pests just buyer beware). Say the non qt'd piece cost $30. How much more would you pay for a qt'd pest free piece? $60, $90, $200? The cost to QT will be the same regardless of it's a $10 brown coral, or a $300 ultra piece. The only factor would be size as it would take up more space in the QT for the 6 weeks.
Would you have paid more for the coral that infected your tank if you knew it would prevented the AEFW from reaching your tank? I suspect you would. I certainly would, and have and will continue to. If you do the math on what it costs in time and coral losses, it is worth it.
