Gold Spike

Founder Effect

This is the latest photograph of a Goleta Dart that a few weeks ago was nearly colorless with a 'gold spike' on his tail. The green splash near the tail is one of the traits that appears every few generations.

Believe it or not this is the same individual that I took a photograph of a couple weeks ago. The 'coloring up' of this guy took place almost literally overnight. The orange spots and geometric body patterns have really started to take hold. It seems like with this strain they get a background color (for lack of a better term) followed by increasing layers of darker and more intricate patterning later on.

Half a dozen males with this phenotype were born into one of the Goleta Darts tanks. The type is nearly devoid of color except for some gold flecks and orange spots around the tail. The bottom sword in the photograph has a metallic gold sheen The body and the white parts are also highly metallic and reflective under aquarium lighting. I separated out a couple of these males in a tank with some females to see if the phenotype could be reproduced.
