With killie eggs, if they turn white, they are usually bad. (That is NOT true of all species.) I had a plastic container of albino gardneri eggs "water incubating" for the two week incubation period before they hatched.

I checked in on them (again) at about 10 days and noticed that they were not the healthy black/gray of most developing killie eggs. I was walking to the laundry sink when somebody winked at me!

Looking closer I could see their little pink bodies developing! DOH! Albinos!

I felt just sick about what I almost did (though not as bad as i would have if they were dumped). They hatched and thrived.

That strain was first isolated and fixed by a Gary Haas in Virginia in the late 1970s. He sent a pair to a show in California where they were picked up by a college student who was raising fish in a loft apartment in Seattle to defray part of his school expenses - well generate his mad money anyway. He back crossed that fragile albino pair to regular gray gardneri of the SAME (location) strain. The first generation were all gray bodied fish with a G/a genetic make up. The next generation threw some a/a fish which were much stronger albinos. The hobby owes Tom Parker a big thank you for his efforts.

Albinism and color morphing is much more common than we might think, happening every so many 1000 or 10,000 off spring. The odd colored fish are usually eaten much more quickly because they stand out in the crowd. Sometimes they are weaker too.
