I've got Charley's pictures also, and they are more colorful. THe adipose fin is pretty convincing, and I will admit that I did not look that closely at the blurry images to notice one way or the other. Nannostumus sp. have adipose fisn, but on some species they are very clear, very small and located very near the caudal fin and hard to see, especially in a blurry image. Those blurry pictures are hard to determine scale too. The fish in those picture strike me as being less than two inches long, but that is just an impression. They also seem to have smaller fins in relation to their body size than the N. crosomus does, and the overall body shape of the male does not look elongated enough (comparing to both my and Charley's pictures). Those observations can be explained away by camera angle and condition of the fish, but without better pictures we will never know.
I will ask Charley for permission to post his images. I have permission to use them for educational purposes, but I will double check.
