Fire Green Tetra (Aphyocharax rathbuni)

Green Fire Tetras are a popular and peaceful shoaling species that are perfect for peaceful community tanks or planted aquariums. It would be best if you kept them in groups of 8 or more individuals in a densely planted tank with fine gravel or sandy substrate as well as roots, driftwood or some river rock for them to hide in. Make sure they have plenty of swimming space.

Although these Tetras are known to be very peaceful, care should be taken when choosing tankmates. Make sure you choose faster moving and robust fish as this species has a reputation for fin nipping. Furthermore, it would be best if you avoided long-finned fish such as anabantoids and several Cichlid species.

Green Fire Tetras need a slightly acidic pH, consistent temperature, and although lighting is not essential, they do best in low light conditions. Tall background plants or some floating plants are ideal for bringing out their beautiful green colours.

Green Fire Tetras are slender, almost spindle-shaped species. They have a very distinctive translucent metallic greenish hue on their body, a metallic yellow streak and a red colour splash on the pelvic and caudal fins towards the anal fin region. These fish also have a black patch on the dorsal fin and a red to an orange underbelly.

Feeding

In the home aquarium, the Fire Green Tetra will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Staeck Endler(Poecilia wingei)

Sexual Dimorphism

It is somewhat straightforward to distinguish male from female Green Fire Tetras. Males are slender, more pointed and have white tips on their pelvic, dorsal and anal fins, as well as being slightly brighter coloured. In contrast, females lack the white tips and are generally more rounded in the abdomen than males, especially when they are in spawning condition.
