Various aquarium strains of SJO

BKA-80 strain of Blue Gularis

"Form circulating in the 1980s in the UK"

If the UK was getting material from Al Mikkelson in the US that would make sense - the very definite margin in the anal fine, very wide caudal and irregular barring are my memories of that fish at the time exactly. Note the big eye indicating a young fish bit but with great color already. Al had won the AKA gularis class after displacing Paul Hoppe's 10 year run in 1976; Al sold a lot of gularis after that.


Not any particular strain I just have lots of photos of these.

I took a lot of photos of one fish that was the result of a cross between Szaferencks's strain of Dwarf Red and whoever won the AKA gularis class in 1988, Mike Epperson if I recall. The fish dispayed four of five phenotypes, small and dark blue, big and light green and this one.


Peter DeSouza's strain of Blue Gularis.

Peter's contemporary (as of 2016) strain is (at least in my opinion) at least as good as any of the great US strains throughout history, as bred by Hoppe, Mikkelson, Schwiengerath and Epperson and others.


us_blue

In Europe "US Blue Gularis" are recognized as a strain of SJO much in the same way in the US the German dwarf red strain is recognized.

It's always been true that in the US certain strains are known to have above average size, color and finnage. It would be a rare fish indeed from the wild that luckd out and got genes this a good and was able to grow them fully out.

Yet it is possible, and much more so lkley in a fiahtank than in the coastal waters of Nigeria or in a small stream in Cameroon. That is, the selective breeding if the US blue strain preserves the best of what a Nigerian SJO can be in a strain that breeds true.

I would not really say it's an artificial tank bred man made creation of something that does not exist in nature, but rather it's a strain, tank bred, to represent the ideal Nigerian SJO.

The names of people in the US involved in this will be familiar to many: Paul Hoppe, Mikkelson, Bob Schwiegerath, Mike Epperson, Rosario LaCorte.

Aquarium mutations and hybrids. While frowned on, hybridization helps us to understand the genetic relationships with other killifish. Scheel reported successful crossings with AUS and GAR although could not keep these fish alive past three generations.
