Martin, I have also seen that slightly lanceolate form of the caudal fin and it’s slightly brownish-reddish colour-tinge. The first aspect reminded me at spec. Langgam in the same way as it reminded you (although this feature seems to be variable in that species), but the second did not. The caudal of spec. Langgam is – whom to I tell that!! – brightly red and not that slightly brownish tinge only. But there is a third small thing that you don’t mention: that very short, but in some positions of the fish clearly visible filament in the middle of the end of the caudal. And I have never seen a spec. Langgam with that property. None of the wild-caught individuals Horst Linke brought home in 2008 (which I saw in original) nor any of your offspring-fish (as judged from your fine photographs) ever showed a filament like this. But I admit, it is not to be seen clearly on that movie. We need still photos in good light! Otherwise one cannot identify rare Parosphromenus.
