I have had long finned paleatus, and bred albino paleatus. The giveaway with the albinos was the tall dorsal of the male. So, I would suspect that if the dorsal is longer on the males, that perhaps they are paleatus. I have never seen aeneus in long fin, so, when I saw the very tall dorsal on the smaller ones, my first impression was that they were paleatus. Perhaps Charlie or someone else can offer a more definitive observation.
