Flame-back bleeding heart tetra

Hyphessobrycon pyrrhonotus

A red wedge along the upper body plus a small shoulder spot

The upper-body red patch helps distinguish this bleeding-heart relative. Mature males develop extended fins.

Use a mature aquarium and prevent organic-waste accumulation. Adult males may challenge rivals and similarly shaped companions.

Appearance and identification

Colour varies with state, sex and lighting; juveniles may lack the adult display. The long white distal anal band helps comparison.

Provide retreats and monitor subordinate fish.

Allow a 75 × 30 cm base; keep eight to ten or more of mixed sexes.

Offer suitable dry and small frozen or live foods; remove leftovers.

Watch territorial interactions, especially with similarly shaped fish.

Plants and wood offer shade and retreats.
