Name: Black Widow Tetra / Black Skirt Tetra. (Pick up only)

Scientific Name: Gymnocorymbus ternetzi

Description: A hardy, deep-bodied tetra with a silver-grey body, two dark vertical bars and a distinctive black, skirt-like anal fin. Active and sociable, these fish make an attractive addition to suitable community aquariums. Their dark colouring often softens as they mature.

Origin: South America; the Paraguay and Guaporé river basins.

pH: Approximately 6.0–7.5.

Temperature: Around 20–26°C.

Adult Size: Approximately 5–6 cm.

Lifespan: Approximately 3–5 years with good care.

Food: Omnivorous. Feed quality tropical flakes or small pellets, supplemented with frozen or live foods such as brine shrimp, daphnia and occasional bloodworms.

Compatibility: Suitable with similarly sized, active community fish and peaceful bottom dwellers such as Corydoras. Keep in groups of at least eight, preferably ten to twelve, to help reduce chasing and fin-nipping. Avoid slow-moving or long-finned tank mates such as bettas and fancy guppies.

Habitat: Provide an established freshwater aquarium with planted edges, shaded retreats and plenty of open swimming space. Driftwood and floating plants provide cover, while a dark substrate highlights their markings. Maintain effective filtration, gentle to moderate water movement and regular partial water changes.
