About Green Fire Tetra

General information

The Green Fire Tetra is a small, peaceful freshwater fish that reaches an adult size of about 2 inches (5 cm). They are active swimmers and prefer a heavily planted aquarium with plenty of hiding places. The water temperature should be between 72-79°F (22-26°C), with a pH level between 6.0-7.5.

Diet & nutrition

Green Fire Tetras are omnivores and will eat a variety of foods including flakes, pellets, frozen, and live foods. It is important to provide a balanced diet and avoid overfeeding.

Determining sex

Male Green Fire Tetras are usually more colorful and have a slimmer body shape than females. Females are rounder and have a more silver appearance.

Breeding & spawning

Green Fire Tetras are relatively easy to breed in captivity. They are egg-scatterers and will deposit their eggs among plants. A separate breeding tank is recommended, with a temperature of around 77°F (25°C). After spawning, the parents should be removed from the breeding tank as they may eat the eggs.

Diseases

Green Fire Tetras are generally hardy fish and are not prone to many diseases. However, like all fish, they can be susceptible to ich, fin rot, and other common fish diseases. Keeping the water clean and well-maintained will help prevent disease.

Origination

Green Fire Tetras are native to South America, specifically Brazil and Paraguay.

Cautions

Green Fire Tetras are peaceful fish and should not be housed with larger, aggressive fish that may bully or attack them. They should also not be kept with fin nippers, as their long flowing fins may be a target.

Acclimation process

When introducing Green Fire Tetras to a new aquarium, it is important to acclimate them slowly to avoid shock. Float the bag in the aquarium for 15-20 minutes to allow the temperature to equalize, then slowly add small amounts of aquarium water to the bag over the course of an hour before releasing the fish.
