I know my photoes are not to be very proud of :whistle: but these of p.parvulus I took with one hand pointing a little torch to spot the fish. At least they show the red spots more than most of my other images of parvulus.
For id-purpose it may be a way to do it, – not for taking beatiful pictures really 🙂
