I bought this Killi from Segrest as a "N. Massoni".
Where can I find a good database?
Any idea of what this fish is and where it comes from?
Thank you for your time!


Hello,
From the name I would guess hassoni.
I found this photo of hassoni: https://www.bubbashrimp.be/us/bubbas-fishs-nothobranchius-hassoni-couple.html which is reminiscent of your fish. But in, all honesty, it doesn’t much look like the fish Bela Nagy collected:

There is some resemblance to the Kasamba River population.
You should contact Bela directly and inquire whether this represents the normal range of variation for this species.
