Taken collectively, these variances indicate that the fish can tolerate a moderate degree of fluctuation in water quality. As can be seen from the table above, fishes of the Apistogramma group are found in waters spanning a range of measurements. Note that, the higher the dissolved solids, the higher the pH and two hardness measurements. Compare these measurements with Ottawa tap water to see if any adjustments are necessary. Fishes of the Apistogramma group have several characteristics which distinguish them.
All species breed in caves or shelters and both parents share in the rearing of the young.
The young are taken care of by the female who defends the territory. Breeding First, with regard to water quality, the pH has an effect on the sex of the fry. A pH of 6.6 to 6.8 should lead to a more even balance of sexes. An aquarium of 10 to 15 gallons is appropriate to breed most species. Water characteristics should approximate natural conditions as closely as possible.
