Spiny Eels?

I am looking for a pair of Mastacembelus sp. "Rosette" or Aethiomastacembelus sp. "Rosette". The species name may have been changed by now but I cant say for sure. They are native to Lake Malwai, Africa. I am having difficulty finding information about them. I want to purchase them very soon. Any help would be greatly appreciated!

Also I found a picture of a Aethiomastacembelus plagiostoma (Tanganyikan Banded "eel")
and the bands around the fish looked blue in the image. I have never seen a picture of a blue freshwater ell before. I think it was the lighting but once again I cant say for sure because no one likes to reply to there email. If anyone would like breeding information about this species I also found a very good post on The Cichlid Room Companion if any cares to read it. (sorry if i shouldnt have posted a link to another forum)

Are there any "spiny eels" that are blue in color or any freshwater eels that have a blue coloration?


 
Cant think of any blue ones, they all (asides from some of the african ones), seem to be shades of brown with darker or lighter spots or stripes or eye spots.... m. aral has a slightly greenish stripe..... and of course the fire eel has the orange/red/yellow markings.
