I reached out to Colin once several months back and he basically told me he only does wholesale now, unless I could come up with several fish I wanted to make it worth his time. I gave him about 4-5 different Hawaiian fish I'd be interested in from him depending on price, and he never really got back to me. So, he didn't seem very interested in a one off order. That said, if we could round up enough to make it worth it MAYBE he'd consider it, but I'm not sure. I got some Potter's from him once that didn't end up making it long term but they came in the healthiest I've seen, save the one I bought off DD that apparently ended up with a case of flukes and died on me. I was so disappointed as it was super healthy and eating prior to that. I really would like to have at least one in my tank though if at all possible.Collin from Zoa collector is in Hawaii, he would be a good source or that guy that Bulk reef supply uses, not to mention skip a few middle man stops. Once it got to your LFS it’s seen so many other tanks and stressful events. That being said I think you buy more than you want assuming you will end up with less. The one I have came from live aquaria I ordered a trio and ended up with one.
Not sure where you are located but kjo is relatively local to me, (Minneapolis Minnesota)
And, I agree, I tend to buy several in hopes of keeping one, which is sad but the way it is with these sometimes. I know @HairyGary has a wholesaler he gets his fish through but that one won't ship the Potter's. So, we could maybe try to pursue Colin but my last exchange with him wasn't real hopeful. Let me know what you think @Jstn via PM.
