That is interesting to learn. It explains the sliding price scale for GH and other high end fish, from juvenile to adult; there are many people in Canada who are willing to buy smaller fish (at reduced price) that have "potential" to be GH. Unless the fish show proven characteristics at time of purchase, however, it will always be a gamble. I suppose there is less of a gamble with buying juvenile SR and XB's since the % chance of the fish developing as hoped for is higher due to succesful line breeding by various farms.
Someone on this forum was posting recently about some DFI GH that sold in Toronto. Thus, there is a market for GH in Canada.
Any chance you can post a video of these fish?
