if not kept on large schools black tetras can display aggressive behaviors amongst themselves, chasing and nipping weaker fishes. A group of 6 or larger is recommended. Avoid mixing them with slow moving, long finned fish like male Betta splendens.
For optimal health feed them every two weeks live foods like daphnia and mosquito larvae, and from frozen foods like blood worms.
Reaching 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. These fish are frequent egg-eaters and must be removed after spawning. The young are easy to raise, subsisting on newly hatched brine shrimp or powdered processed foods.
