    Yesterday it rained all day and the temperature dropped dramatically. I had to get a sweater out of mothballs

    I now believe this liverbearer is a Molly. Poecilia. gillii. The male reaches 6 cms and the female 10.5 cms.
    However I was not actually told about the “birds and the bees” so I am a little fuzzy on this subject.

    Hey John

    Wow lovely looking fish.

    Only male Mollies have gonopodiums.

    Fish in the photo. above looks like a female and those above are males. The fins of the sexes are very different in shape.

    Females release fry approx. every 30 to 40 days. Numbers of fry increase as the female ages.

    Regards David

    Thanks David, here is a photo of the male with the dorsal fin open, showing the different shape.

    The problem now is that if these are P.gillii then the databases are wrong concening the sizes. They have got it backwards and the males are much larger then the females.

    Another fish that came to me from this trip has turned out to be a Jack Dempsey. I had been asked to search for the Rocio but possibly in the Lake.
    Although this is a youngster it is probably not Rocio.octofasciata but R.ocotal a new species described by Schmitter-Soto in 2007. This was found in Laguna Ocotal a very isolated body of water in the highlands of Chiapas just over the border from the Peten and thought to be endemic.
    So this has turned out to be a very interesting fishing trip.
