Nannostomus marilynae

[PhilipAG]

A year ago I was looking for these guys but couldn't find them.

Now a shop in the Netherlands has posted a video on youtube and I was wondering if these are the real N. marilynae or misidentified N. digrammus?

These fishes show a tertiary horizontal stripe (on the belly). Nannostomus digrammus never shows this.
However; there exists a Nannostomus cf. digrammus with a tertiary stripe...
In Nannostomus digrammus and also in the "cf."-form, the anal fin of males are very elongate, reaching the caudal fin when adpressed to the body. As far as I can see the males' anal fin in the actual fishes are not greatly modified or elongated.
So; these seem to me to be Nannostomus marilynae.
