Hi,
I think that Parosphromenus bintan have little differences of the feature in the south area and at the center area.
The body side of Bintan in the center area is very red.
And, I found the third Parosphromenus in Bangka.
It’s the west of the Bangka island.
This is neither deissneri nor bintan.
Fin color is red, and there is no pattern.
It looks like anjunganensis a little.
And also body color is red.
However, the habitat was destroyed.
Someone, please look for this!
I have GPS point.
It is about 10km from Mentok!
