Here is a very crappy pic of my male from my phone with lights off in the room and the tank. He is a bit skittish so it will take some effort to get a good pic up close. White Knights are not a hybrid. They are a leucistic form of S. fryeri which first popped up in Australia through captive breeding efforts. I don't know if they exist in the wild, but the gene came from the wild so it is likely that they do, but probably very rarely. As you can see they do not have any pigmented color in their body or fins, blue not a pigment in fish it is a reflective protein. Eye color not affected because it is from another set of genes.
All fry look exactly like the parents, with the same distinctive body shape and proportions of typical S. fryeri. I haven't tried to outcross them with wild type or albino forms to this point. When I do so I will post my results. If the genetics work the same as other species I have worked with I should be able to get a fish recessive for both genes, or a red eyed white knight.
It appears that the two types, albino and leucistic, have been confused for some time now on the web. The first white knights popped up a few years back but very sporadically. I picked up a group of 10 fry under an inch in length along with a few other breeder colonies of peacocks and haps. Got rid of all the others when I moved but I couldn't bring myself to give up the white knights, just too different from everything else that I see out there and apparently nearly impossible to get again. I work at a shop that has been trying to get them in for a couple of years now, but every time they come in as albinos.
