Jenynsia: One eye on each side, one-side livebearer. Most people separate them from the Anablepidae. This is the experience of Martin
Tversted from Denmark with them: J. multidentata is distributed from coastal Argentina along the coast up to Brazil. J. lineata has a very limited distribution area. It is limited to a single river system inland Uruguay. They’re 7-8 cm for the females, the males are smaller. They give birth outside
despite 8°C. They are very coldtolerant.
My fishroom keeps beetwin 8°C and 14C°
in the winter and here they live with all the other fish that are
outside in the garden pond in a 500 liter aquarium. The fry grows rapidly on
livefood outside (they’rte about 8-10 mm when born). The sistemathyc about
this genus isn’t still complete and new descriptions and ideas are
coming out… so we can’t give you a complete overview of all the
species… You’ll get more
