The maxillaris pristellas belong to the family Characidae which is one of the largest family with 1300 known species. The pristella genus comprises only two species: pristellas ridlei or maxillaris and pristella aubynei. They are also called goldfinches. Among the pristellas maxillaris, there is a so-called “golden” variety.
Anatomy of Pristellas Maxillaris
Their bodies are slightly elongated and compressed laterally. Their mouth is pointing upwards.
Pristella maxillaris has a predominantly gray body, transparent at the top. The caudal fins are orange. The dorsal and pelvic fins are each punctuated with a black spot and a yellow spot.
The golden pristella maxillaris is predominantly yellow. His body is partly transparent on its upper part. The caudal fins are orange, the dorsal and pelvic fins each have a yellow spot and a white spot.
These fish measure about 5 cm, the female being slightly larger than the male.
Specific needs and nutrition
The pristellas live in the wild in Brazil and Venezuela. They are not very demanding on the composition of the water: the pH must be between 6 and 7, the temperature between 24 ° and 28 °. The pristellas appreciate aquariums well planted, with free areas for swimming. They like to shade themselves in the vegetation. These are gregarious fish that must be kept in schools (minimum 8 individuals). They swim mainly in the middle and at the bottom of the aquarium, but quickly rise to the surface during the distribution of food!
The pristellas are voracious, and eat both dry and frozen food: straws, worms, artemias, mosquito larvae …
The pristellas, whether “golden” or “classic” mix very well. The pristellas “classic” are brighter than the golden ones and therefore more difficult to take pictures!
Reproduction of pristellas maxillaris
The tray must contain fine-leaved plants. The water must have a pH of about 7 and a temperature of 25 °.
The female lays her eggs in the plants, usually in the morning, the laying lasts on average 1 hour and a half.
Then you have to remove the parents. The fry can feed on their yolk sac for about 4 days. Then we can feed them with Artemia nauplii
