Origin
- A South American fish which is found in the Lower Paraná and Uruguay River basins.
Sexing
- Males are brightly coloured, while the smaller females tend to be brownish-grey.
Breeding
- Set up a species tank, with a 2" layer of peat, and several hiding places for the female. The spawning embrace takes place, and the eggs are deposited in the peat. Remove the peat and eggs, squeeze most of the water out of the peat, put in a plastic bag and wait 2-4 months before placing the eggs back in fresh, soft water. If hatching doesn't occur put the eggs back and try again later.
