I've been trying to get a good shot of the fins on this one for a while, and tonight I finally managed to get a couple of half decent ones.....

Compared to some of the Wifi's (wide fins) that Ken Kennedy has produced, it's not that spectacular, but I'm pleased that the Wifi influence extends to all three unpaired fins, notice how both the anal and dorsal fin extend behind the caudal (tail) fin. What also pleases me, is that this fish has no Ken Kennedy ancestors, so it should make a good cross to some of the fish I have decended from his stock. Especially as there's a 50:50 chance that it carries a pb gene.

At present, the genes and/or other factors that produce a wifi fish are not understood, but one thing I've noticed is that fish displaying wifi tendancies seem to be slower growing than their non wifi siblings. This fish for instance, is 8 months old with a body diameter about 20% less than some of it's more normal finned siblings.

Another possible piece of the jigsaw, is that some of my fish seem to have spectacularily long fins. My avitar (below) for instance is the half brother to the fish above....

His father was a Ken Kennedy fish with moderate wifi tendancies. He and his siblings all grew rapidly, and most developed nice long fins, but no obvious signs of wifi.

What I'm wondering is, do the gene(s) necessary for wifi cause the fish to grow slowly, or, do they produce wifi only in slow growing fish? and in faster growing fish, do they produce slightly longer fins than standard?

One final thought on this, Graham (Grummie) has noted that all the best wifi's seem to be pearlscales. Other's have noted that pearlscales seem to grow more slowly.

It's a conundrum isn't it. I'm sure if someone can find this answer it's you! Beautiful fish btw.
