Crenicichla regani ID please

[peterK]

Hey all!
Could someone tell me what form of C. regani I have? I think it could be 'Alenquer'. They (pair) are F1.
Male:

Female:

In my opinion, if a species arrives without a collecting locality, then you should NEVER give it one. You could be wrong and could mess up someone's pure population by mixing.

I have to agree with Mike. C. regani populations are wide ranging and are not significantly different from each other to make a guess at location. I have had the Tapajos population before, but the pheotypic diversity within the group of twelve I started with (all wild) was broad. Occasionally a geographic population is so distinct that they can be easily differentiated, but those are often the most likely to be given species status eventually. The best example I can think of is Pelvicachromis taeniatus 'Wouri' which is distinct from all other P. taeniatus.

OK thanks for informative replies! I hope they both come from the same locality...

Hey!
Owner of the shop where I bought my Crenicichla told me that they are F1, from wild C. regani "Rio Negro". So everything is ok:wink:

P.S. I hope they'll spawn soon - female swims with the male all the time and she looks like this

I am not sure, does C. regani occur in the Rio Negro? Maybe it does in the lower part, but C. notophthamus is the dwarf pike for most of the Negro.

Hi Mike
As far as I know, parents of my fish (my are F1) were imported by Amazon-Exotic-Import, which co-operates with shop where I bought my C. regani pair. They (A-E-I) had wild Crenicichla regani 'Rio Negro' once. See this:

So have anyone an idea where they really came from???

BTW, my female is guarding larvae, I think
