Hi Ormet.
Sorry for a little late reply.
The fish in the photos are not easy to determine, – the first could be a phoenicurus female, but to be honest, I am not sure.
The last like a male, but again, – not really sure that is a phoenicurus. They may be rather young fish also.
We would need better photos, with more flashing behaviour, – it is possible also in brown water – but sometimes it takes a long time. And if fish is young of course it will not happen just like that.
The location mentioned, of course as far as I know sound correct in regards to phoenicurus, – but then again, – it may not be an acurate or even ‘true’ locality.
So, my advise 🙂 to wait, and in any case appreciate the fish whatever species it may turn out to be, – there always interesting aspects to be found.
Kind regards Helene
