He's very conversant about freshwater goby.
I have associating with him for several years.
Please pay attention to a text of this URL.
" nijiiro" is Japanese and the meaning is "Rainbow-color".
Those selling name is a rainbow color bonze goby, a red fin neon goby, an elegant bonze goby in Japan.
The most of Stiphodon imported from the Asian neighborhood of equator are "Rainbow-color" in Japan.
Probably I suppose that the situation is the same in the Europe.
The scientific name of "Rainbow-color" is unclear.
There is not the conclusive evidence whether they are single species.
Even the ichthyologist who performed their DNA analysis avoids the identification of the scientific name.
It is difficult for an amateur to distinguish it only by a color and a pattern.
This scientific name notation is an error.tyrano34 wrote: stiphodon elegans ( yes or no)

The Japanese name is written definitely.
This is S.percnopterygionus.
I believe that 2 upper pictures are S.elegans for certain.tyrano34 wrote: http://w3.u-ryukyu.ac.jp/coe/action/new ... wsl10.html
have see so many different pictures on the Stiphodon elegans.
This website is the one from University of the Ryukyus, and a photographer is Maeda doctor of ichthyographer.
It was investigated scientifically at a Tahitian Moorea island.
Dr. Mukai of the ichthyologist compared DNA of "Rainbow-color" with S.elegans.
Though "Ranbow-color" is a close species according to it, it seems to be another species.
Stiphodon can change the body color and the pattern drastically.
All following pictures are males of my S.percnopterygionus.(plural male states)
I made realize that it's difficult to see variety of my S.percnopterygions
and specify the species of Stiphodon by a little difference between the body color and the pattern.
Only the male of S.percnopterygionus is long and a sharp dorsal fin is characteristic, so it can be distinguished.
