BLEEKER, 1860 Three species belong to the genus Girardinichthys. Unfortunately, one of these species is also threatened by extinction. These pretty and rather peaceful fish are difficult to keep, because permanent water temperatures over 22 °C can be fatal. Hence, the temperature should be kept between 17 °C and 20 °C. The dorsal fin and anal fin are quite big compared to other Goodeids. The species of this genus can be easily nourished with all standard food (flake food, frozen food and living food) and they will breed well. The trophotaeniae of the embryo have two long front and two shorter back extensions. Pregnant females become very round just before giving birth to their young. Development of Girardinichthys 1 = after the 7th day 2 = after the 16th day 3 = after the 22nd day 4 = after the 55th day |
