Flame tetra (Hyphessobrycon flammeus) – freshwater, gregarious aquarium fish from the tetras family with low demands and a lively temperament.


Central America . The species inhabits only the rivers and streams of the Rio de Janeiro basin.

Characteristics and disposition

The red tetra is an easy-to-breed fish, often recommended for beginner aquarists . Lively, gentle and willing to swim in the company of other tetras.

Best kept in a small group or shoal. Single individuals tend to be somewhat territorial. Fully pigmented specimens show a red spot on the back of the torso and two dark, parallel stripes behind the gills. Females are slightly rounder and less colored than males , which can be distinguished by the red, black-edged anal fin.

Nutrition and feeding

Omnivorous fish , not very picky.

She can be given small live food (eyelash, daphnia, mosquito larvae), frozen and dry.


The red knots should be kept in a herd, in an aquarium of at least 54 liters, with not too bright lighting and a dark substrate, emphasizing their beautiful coloration. The tank should be densely covered with plants and at the same time have enough space for swimming. More intensely lit tanks should be darkened in places, e.g. with floating plants.

The colors of red rapids fade in brightly lit aquariums such as pet stores. Fish feel good in both soft and hard water. Best kept in a species aquarium or community tank with other small fish.


Reproduction is not difficult . Place the aquarium in a shaded place.

At the bottom we pour coarse-grained gravel or put a protective net. This will prevent the roe from being eaten by adult fish. The water should be very clean, soft to medium-hard, with a pH of 6.5 and a temperature of 24-26 ° C. One week before spawning is scheduled, it is best to separate males from females. In the evening, place a few rapids in the breeding aquarium (5-10 l).

Spawning usually takes place the next morning. After spawning, adults are caught. Up to 500 fry can be seen after a day. After 3 days, the little fish begin to swim in search of food. We feed them with small live food (copepod larvae, brine shrimp, artemia).
