    These was in our stores a while ago.



    The males have this gill plate extension thingy besides the extensions on the caudal, anal and dorsal fins. Notice the filament that ends with a white dot near the lateral line? It moves. Not sure what is the function though...


    I thought it is quite cute with all the extensions flowing as the fish dance around the tank. Anyone keeping these?

    very nice! I had some very long ago but their finnage weren't so long.
    why I don't do garden hybrids and aquarium strains: natural species is a history of Nature, while hybrids are just the whims of Man.

    Prowl the LFS more often lor. Saw in 3 places. I think most people thought they are feeder swordtails.

    I let mine into my "pond" long ago as their sword weren't very long. I think there is at least one still around but really hard to see.

    The gill extension is supposed to be a secondary sexual organ that secretes a chemical to attract females.

    Ooo. That's interesting. Too bad the females died.
    Thanks Matt for the information.

    i had tried with 12pcs from C328 & all died off so easily....main reason - the sword became target "food" for some of my dwarf cichlid & other tetras. Once injured, they are soon died from the bateria attack from the wounds.
