There is no white edge to the dorsal fin of L100 (the white edge is present in A. dolichopterus).

Hi,
that´s not all right.

There are adult A. dolichopterus with white edges at the dorsal fin, but also specimen partly loosing the white edge and specimen loosing the white edge at all.
This difference is even obvious in specimen coming from the same clutch.
For an exact declaration you should know the origin of the fish.
