What's up bubby? How did your calico project work out? But I think you should be able to make them from scratch. I hope someone with some real experience could shed some light on this question.
Sadly they passed a while back. The tank they where in got poisoned. I've been trying to see what I can find on google but nothing really. I remember on one of the old calico threads someone posted a link to a good site that had more info on the calico gene.
Well I think like any con the parents would have to carry the gene. How they get it I'm not sure. The way it's described it seems impossible but it's not.
Found a link that gets us that much closer to figuring it out. "Greg the fish guy" goes more in depth explaining them here... http://www.cichlid-forum.com/phpBB/viewtopic.php?t=132356
That poor mans hrp/electric blue con is NICE!
