    In the morning my assistant netted the shallows and we collected about 20 Mollies and an assortment of very young cichlids.
    We have not determined the Molly species we will let this lot grow up.

    My young fisherman was supposed to do some fishing in the afternoon. By lunch time a storm had rolled in and the Lake was too rough for comfortable fishing in a dugout. Dugouts are unsinkable but if waterlogged they make fishing difficult.
    As an alternative he went along the shore to a new location and netted a new species for us, No other fish were found here only these. They could be adults as they are between 6 and 7 cms long. They are a schooling fish with livebearer type tails and the wide flat head with the protruding lower lip. The dorsal fin is immediately above the orange coloured anal fin. A very slow moving fish. We have not succeeded in identifying it yet.

    great pics, looks like a gambusia type, but is there any sexual differences such as gonopodium or andropodium?

    Hi Keith
    We have 4 Gambusia species, these are much smaller fish and have the typical livebearer shape.
    The 8 fish that I now have are all identical as in the following photo.
    I have been through all the 34 Poeciliidae genera here without any luck. I may have missed a few as many times photos are hard to find.
    Because of its body shape I am having my doubts about it being a livebearer.
    It has little colour and being so lethargic it is probably one of those forgotten species.

    Could all be females?

    The opposite crossed my mind, perhaps they are all males.

    Looking at the 20 young Mollies that I have in another tank they all have the shape of females. I did have some nasty thoughts. I was thinking about adding one of my male black Mollies to sort out the boys from the girls.

    That actually looks more like a Brachyraphis.

    Brachyrhaphis hartwegi
    Of the 8 species only one is found in Guatemala. B. hartwegi is deep bodied while the others are slimmer. Apparently the only difference between the sexes is the gonopodium. Their habitat where we captured them is exactly as described.

    Looks like you have been and gone and done it again.
