How to differentiate between the species/sub-species of lampeye killies?

Hi AQ,

How to differentiate among all sub-species of the lampeye killies such as Poropanchax normani, P. myersi, P. luxopthalmus hannerzi and P. luxophthalmus luxophthalmus?

Hey there.. not sure about where to get descriptions, but you can perhaps try to use this website http://www.killi.co.uk/lampeyes.php for photographic identification.. they don't have photographs of all the separate species, but most of them are there

The ones commonly seen in singapore are usually P. normani, i think.

Hi FishSoup, the website that you've linked doesn't have much photos on the Poropanchax spp.

I have by, sheer luck, stumbled in this website where there are more photos on Poropanchax spp.

Killifish of Western Africa - Poropanchax index

They are differentiated primarily by the finnage patterns. If you need help let me know.
