I guess I haven't found the NZ Guppy Keepers Association yet, where do I sign up? :roll:
I don't care that HFF doesn't stock killi's, and I guess the majority of their customers don't either otherwise they would probably stock them. LFS's can't keep every species of fish in stock, its just not profitable, as you said youself there are only 40-50 people in the NZKA so they obviously have more of a cult-following than mainstream appeal. My point with the killi's is not so much that they get sold privately, its that the 40-50 people who have a real interest in them are a fairly close-nit bunch who regularly trade fish with no desire to make a profit out of it. There's no way a business can compete with that. Yes plenty of other fish are sold on trademe and by other means, but they are usually far more mainstream things than killifish so the shops can still make money selling them to their customers.
