🙂 This species is a tricky one. As I have been writing I had a very succesfull spawning with it, with about 40 fry. Of these most unfortunately was males, but a few females luckily.
I have kept some of them in a 60 liter tank, – mostly males, – and when I have seen these together they still only show a little red. Some of the very subdued males almost show no red.
But today I have found a male and female that were clearly showing mating behaviour in this big tank, and I have seperated them into a small tank.
Even it was a bit stressfull to catch them (finding the right male and the female) it took less than five minutes in the little tank before they were in and out of the new cave 🙂
And now I clearly see the red and the resemblance to p.tweediei is much more striking.
The species is in the last Census as P.tweediei (Ruinemans 2013) – and I am not so much in doubt about that anymore.
This is the species which we actually also talked about – and I showed a few photos of – at our recent meeting in Hamburg
