yeah, coral glow is definitively weird. first they believed it to be dominant, then noticed that somehow they got a lot of female coral glows but failed to hit a male coral glow, then this turned into a morph issue and got listed as such. then the first male coral glows were produced. and then you got these clutches where all males looked normal and all females looked like coral glows, and then people figured it out.
now it seems well-understood to me, and male coral glows are much more expensive than female ones. at nerd its 20000 for a male and 12000 for the one female they have. now the gene is listed as co-dominant.... that will change i think. i would call it a sex-linked recessive gene.
