Food and Feeding

Hyphessobrycon pulchripinnis is an omnivorous species that accepts a wide variety of foods. A high-quality flake or micro pellet should form the staple diet. Supplement with live or frozen foods such as daphnia, brine shrimp, bloodworms, and Cyclops to enhance coloration and overall health.

They will also accept finely crushed flakes and small granules. Feeding small portions once or twice daily is recommended. A varied diet helps maintain strong coloration and breeding condition.

Origin

Hyphessobrycon pulchripinnis originates from South America, primarily the Tapajós river basin in Brazil. They inhabit slow-moving tributaries and floodplain waters with soft, slightly acidic conditions and dense vegetation.

Tank Setup and General Care

Lemon Tetras do best in planted aquariums with subdued lighting. Floating plants help reduce stress and encourage natural behavior. A dark substrate enhances their yellow coloration.

This species is a schooling fish and should be kept in groups of at least six individuals. Larger groups improve confidence and reduce stress. Gentle filtration and stable water conditions are preferred.

Temperament and Compatibility

Hyphessobrycon pulchripinnis is peaceful and suitable for community aquariums. Ideal tank mates include other small tetras, rasboras, Corydoras, dwarf cichlids, and peaceful community fish.

Males may display mild territorial behavior toward each other but rarely cause harm. In groups, they display interesting social interactions and improved coloration.

Sexing

Males can be distinguished by the thick black line along the anal fin, while females display a thinner line. Mature males often show more intense coloration. Females are typically slightly fuller, especially when carrying eggs.

Breeding

Hyphessobrycon pulchripinnis is an egg-scattering species. Spawning usually occurs at daybreak. The female may lay up to 300 eggs among fine-leaved plants or spawning mops.

The adults should be removed after spawning, as they may eat the eggs. Eggs typically hatch within 24–72 hours, and fry become free-swimming shortly after. Fry can initially be fed infusoria followed by newly hatched brine shrimp.

Lifespan

Lemon Tetras typically live between 4 and 5 years with proper care. Stable water conditions, group keeping, and a varied diet help maximize lifespan.

Short Description

Hyphessobrycon pulchripinnis is a peaceful schooling tetra from Brazil. Best kept in planted aquariums, this species displays bright yellow coloration and interesting social behavior. Suitable for community tanks with other peaceful fish.
