I think the price is higher as there is no-one in the city of Toronto that seems to be breeding them and none of the LFS want to bring them in as they are a more expensive fish and thus a bit more difficult to sell.
Who is the supplier and where are they located in Toronto as I too am interested in purchasing some. Maybe if the two of us buy a batch of them the price might go down. But 7.99 is a tad bit expensive even for them as it is not difficult to breed them.
They are at the North American Fish Breeders in Scarborough. I called them resently and they told me the price, but they said they were out of stock and that they would have more in 2 weeks. I was planning on buying 6 or so. Just enough for breeding.
