Feeding Guide

Betta rubra are micro-predators and require a protein-rich diet. Offer a variety to keep them healthy and vibrant:

• Live foods: Daphnia, baby brine shrimp, microworms

• Frozen foods: Cyclops, bloodworms, mysis shrimp

• Pellets: High-quality micro-pellets or soft betta-specific granules

Feed once or twice daily in small, manageable portions to maintain excellent water quality.

Breeding Betta Rubra

This species is a paternal mouthbrooder—after spawning, the male carries the eggs in his mouth for about 10–14 days. Key breeding tips:

• Keep water parameters stable and soft

• Provide secluded spots and plenty of cover

• Offer live/frozen food to condition the pair

• Keep disturbances minimal during the mouthbrooding period

The fry can be raised in the same tank or moved to a rearing tank once released by the male.
