[Peter Finke]

In identification matters I am mostly unanimous with Bernd, but not this time. First: I cannot see a clear dark spot. The colouring in the first photo is typical for a fish in a frightened situation, displaying several unclear weak spotlike patches. Second: the other fish is coloured in quite a different way, interestingly I admit, but the typical star pattern in all unpaired fins that P. pahuensis shows even in a rather young age is missing totally. Besides, the colour pattern in th end of the tail fin is different. This is an interesting fish and I cannot identify it at all. All Paros known to me do not match this pattern. Both fish may well represent different species.
But it is too early to quarrell about this. Both fish are still too young, do not show full courtship colours, and the photos are bad. Be patient for some weeks and repeat the photos with a better technique.
