Diet/Food & Feeding Habits

    In general the Black tetra is easy to find and easy to care for, a good beginner fish. The black tetra is a common fish that can be readily acquired from aquarium dealers.

Compatibility/Tankmates:

    Although not generally aggressive towards other species, black tetras can be violent amongst themselves, with weaker fishes often chased and nipped by their superiors.

Sexing:

    Can be difficult to determine, female may be more full bodied.

Breeding/Spawning:

    The black tetra reaches sexual maturity at about two years of age. They will spawn in water 78 degrees F. A separate spawning tank, heavily planted and at least 15 gallons, is recommended. Like most characins, black tetras spawn by intermittently releasing and fertilizing eggs among the plants. Although these fish are not frequent egg-eaters, they may be removed after spawning. The young are easy to raise, subsisting on newly hatched brine shrimp or powdered processed foods.

Coloration/Fins:

    This fish is greyish in color, fading from light at the nose to near black at the tail. Two prominent black vertical bars appear just posterior of the gills.
