To begin with, it is *bualanum* not *elberti*. Check the letter Huber
posted to the AKA early this year. You will find a link on the AKA
home page. Also, all the above speices are s in the subgenus
*Kathetys* according to Henrik Korzen.

They are all very closely related. Crosses between the valid
species yielded sterile hybrids as determined in work by Scheel.
I don't think the species are determined by colour. More than likely
scale counts etc...

It is the *exiguum* group. They all look like *exiguum*: bright blue
background with red verticle bars and funny sickle fins.

Like most rainforest fish I doubt they would be happy above 24 deg
C. I suspect the temp will have to be lower for breeding.
If I recall correctly, they have been caught sympatricly with various
Chromaphy. species and can be treated in the same way.

Questions is why the list exisits. Questions also make for good
