The Apistogramma macmasteri is a popular and beautiful dwarf cichlid, known for its robust nature and ease of care and breeding. Native to the upper Meta River and Orinoco river basin in Colombia and Venezuela, its natural habitat features soft, acidic water with sandy substrates, dead roots, leaf litter, and dim lighting.

Physical Description:
This species has an elongated oval body, iridescent blue with yellow patches, and reddish-orange fins. Males grow up to 5.5 inches and are more colorful, while females reach about 4 inches.

Temperament:
Generally peaceful, males may become territorial during spawning. Captive-bred specimens are more docile than wild-caught ones.

Care Requirements:

• Aquarium Size: 15 gallons for a pair; 30+ gallons for groups.
• Substrate: Soft, sandy substrate with optional leaf litter and driftwood for hiding spots.
• Water Conditions: Soft, acidic water (pH 5.5–6.8), gentle flow, and dim lighting (max 8 hours/day).
• Tankmates: Captive-bred fish can live with peaceful species, but compatibility varies by individual.

Diet:
Primarily carnivorous, they prefer live or frozen food like bloodworms and brine shrimp. Wild-caught fish rarely accept dry food, while captive-bred ones are more adaptable.

Breeding:
Pairs can mate for life or temporarily. They spawn in cave-like structures, attaching eggs to ceilings. Depending on the male's aggression, the female or male may care for the eggs. Fry can be fed freshly hatched brine shrimp.

Under the right conditions, Apistogramma macmasteri offers rewarding care with its unique personality and behavior.
