I only deal with stateside wholesalers - for clarity.
My practice of keeping my sources to myself is not unique. Many people in many industries consider this sort of thing a "trade secret" and don't share info with their peers, whether they be near or far.
While it's true that a store 1000 miles from me (or even 100 miles from me) may not be competing for the consumer's dollar, we would end up competing with each other for the supplier's offerings. We both order the show coral that appears on the list, and only one of us gets it. A simplified example, but a valid one nonetheless. All livestock is not the same or equal. Mass produced hard goods are one thing, livestock is a whole other animal - literally.
The suppliers I use aren't secret insofar as anyone can find them - they are out there with all the rest, they advertise, they solicit new customers (other stores) and anyone here could easily find them and buy from them - so it's not like there's any cloak and dagger drama associated with them. Last time I spoke with them, I wasn't their only customer either (although they treat me like I'm their only customer!) so it's not my "job" to increase their customer base. That may sound harsh, but it's not meant to be, it's just a matter of fact. Now... if that supplier gives my name to a prospective client of theirs, for a customer reference, yep, they can call me up and I'll give them a glowing review. This is one of the things I did when seeking out these suppliers - one offered up a couple of references and I made the calls. After that I asked for client references and followed up on my own. Just sensible business research that very few people actually do due diligence on.
I had to learn from trial and error, so what's wrong with others finding their suppliers that way too?
Besides, different peoples' definition of a "great" supplier varies. Some (most?) want everything available, all the time, at the cheapest price. If that's what they are looking for, then my info would likely be useless to them, because my definition puts higher priority on the quality of the specimens (health, ethical collection practices to the best of my knowledge) and less on how much they cost. I'd rather pay a bit more for something that is more likely to live, and less likely to have been collected in a harmful manner, than something that got juiced and cost less than what everyone else is selling for. That's just me.
Nobody is preventing those suppliers from finding new customers. I don't ask for or demand exclusivity, and I don't expect it either. The store down the road is free to order from those same suppliers, as the wholesaler is free to court that store's business.
I typically don't ask other store owners who they order from because I consider it bad manners to expect them to give up their trade secrets. I'm not alone in being low-key about mentioning who my suppliers are, very few volunteer where they are getting their stuff from. IME the only ones that usually do are using the big box wholesalers so there's no "fear" of losing out because they all have "everything, all the time". It's actually kind of funny to be in a store full of what I would consider substandard livestock, and have the owner/manager boast about their supplier... oh if only they knew! Now having said that, it could well be that the specimens arrived in great condition and if the husbandry practices of the shop stink, well even the nicest stuff is going to decline and fast... I was in FL this past weekend and we went into a LFS and I was appalled with what I
saw. The guy had a few really nice fish and a few very nice corals but the rest were half dead, mostly dead or looking like they'd soon be dead... even the best supplier in the world doesn't matter if you don't take care of them once they arrive.
Been there, done that with huge suppliers (when I first opened and didn't know any better because the store I worked at used the big boxes), and often I found that the little store gets the dregs in the big pool of customers at a big box. So I prefer to spend my livestock dollars with entities that give a damn about me as a client, as well as where their specimens come from. I'm a small shop so I don't have the big buying power that a large outfit has. Who are you going to disappoint? The larger store that spends $100K+ a year with you, or the small one that maybe spends $25K with you?
So my suppliers are not "under the radar" garage entities, they are legitimate suppliers that anybody with a business license to sell aquatic organisms can find and purchase from. I do know of some of those under-the-radar entities, or entities that are questionable, and there's always somebody offering to "snag a few things" for me on their trip someplace, and on those I always decline and remind them of the legal issues that can arise from that. Some folks think they can just help themselves to whatever they find, wherever they may be.
Since I have no firsthand experience with those that I believe to be less than legitimate, I can't blow any whistle without putting myself at risk. All I can do is conduct my own business in an above-board and legal way.
I don't like those that operate in a questionable fashion, but there's little I can do about it and as long as there are stores (online or brick and mortar) that see it as OK to do business that way, they will continue to exist until somebody makes it stop. The current "inspection" process at least in my state isn't going to do that. I recently underwent my annual Department of Agriculture inspection and the inspector asked to "see" invoices... I held up the file that contains them and opened it and she checked off that box on the inspection report. Didn't look at the invoice, or see if the specimens itemized matched those in my tanks, so it seems that it's pretty easy to fudge...but again I digress.
I have enough to do every day without becoming the wholesaler police.
And if some of you find it amusing or petty or not nice because I'm not sharing the knowledge that has taken me 9 years to accumulate, I'm OK with that.
