nc_nutcase is right. If you get on allthingsdempsey.com those guys on there have been working with EB & BG for long periods of time and say the quality is actually getting worse and they don't know why. They get very few sellable fish from the spawns. And your talking hundreds of fry in good spawns. It takes serious time and work to get good quality from such a weak strain of fish. That is the forum to be on if you are serious about buying or breeding EBs.
