The flame tetra is native to Southeast Brazil, where it occurs in coastal parts of Rio de Janeiro ( Guanabara bay region, and Paraíba do Sul and Guandu River basins) and São Paulo (upper Tietê River basin). The tip of the anal fin on the male is black, while on the female the fins have less red colouration but darker tips of the pectoral fins.ĭistribution, habitat and status All the fins are red except for the pectoral fins, which are colourless. The rear half of the body is flame red while the area in front of the dorsal fin is silver crossed by two dark vertical bars. With that said, green fire tetras shouldn’t be added to community tanks containing long-finned fish because the tetras nip at the other fish’s long fins.Īs an easy-to-care-for fish, green fire tetras bring a dazzling luminous color to tanks and have a peaceful but curious nature.The flame tetra reaches about 2.5 cm (1 in) in standard length.
A group of green fire tetras will bring color and excitement to an aquarium. Green fire tetras are a great addition to a peaceful community tank or a new tank setup as long as you have enough room for at least five. Should You Get a Green Fire Tetra for Your Aquarium?

Green fire tetra fry hatch with food in their bellies and don’t need to be fed until they begin swimming around freely, which should happen in five to six days. The fry will hatch within the next five days.Remove the green fire tetras from the breeding tank.Once the eggs are laid, the male green fire tetra will fertilize the eggs. The male green fire tetra will chase the female fish around until the female lays eggs on a flat surface.Decrease the light in the breeding tank because green fire tetras prefer to breed in dark areas.Females that are ready to breed will have bulging bellies. Place three egg-carrying females with two males into the prepared breeding tank.All types of tetra fish are prone to a sporozoan disease known as “neon tetra disease”, which has no cure. Green fire tetras are sensitive to toxins and pathogens found in dirty water. Another cause of color changes is disease. Tank water should be filtered to create a moderate water flow and to keep the tank water clean.Ĭolor changes in green fire tetras usually signify stress due to unstable water conditions or predators.
Green fire tetras require certain water conditions to stay healthy, but the fish can adjust to minor water changes. Tank Conditions Water type: Soft, freshwater Tank size: 15–20 gallons (for a group of 15 fish) Water temperature: 72–80☏ (22–27☌) Substrate: Dark aquatic soil or sandy substrate Tank setup: Live plants, driftwood, floating vegetation Acidity: 6.5–7.0 pH Water hardness: 4–8 dGH Filter: Yes, a bio-wheel filter is recommended to keep the tank ammonia-free and to create moderate water flow Bubbler: No, a bubbler is not necessary for a green fire tetra tank A dark aquatic soil or sandy substrate will provide enough nutrients for live plants. Because green fire tetras don’t burrow or feed in the substrate, substrate choice isn’t of high importance.
