Introduction
The Blue Acara (Andinoacara pulcher) is one of the most rewarding freshwater cichlids you can keep. With its shimmering blue-green scales, peaceful temperament, and engaging personality, it's a favorite among hobbyists of all experience levels. This guide covers everything you need to know to keep your Blue Acara healthy, colorful, and thriving.
Species Overview
- Scientific name: Andinoacara pulcher
- Origin: South America (Trinidad, Venezuela, Colombia)
- Adult size: 5–7 inches (13–18 cm)

- Temperament: Peaceful to semi-aggressive; one of the mildest cichlids
- Difficulty: Beginner to intermediate
Tank Setup
Tank Size
A minimum of 30 gallons is recommended for a single Blue Acara. For a bonded pair, aim for 55 gallons or more to give each fish adequate territory and reduce aggression.
Water Parameters
- Temperature: 68–82°F (20–28°C)
- pH: 6.5–8.0
- Hardness: 6–20 dGH
- Ammonia/Nitrite: 0 ppm at all times
- Nitrate: Keep below 20 ppm with regular water changes
Substrate & Decor
Blue Acaras are natural diggers, so a sandy substrate is ideal. Provide plenty of hiding spots using rocks, driftwood, and caves. Live plants like Amazon swords and Java ferns are great additions — just be aware that Blue Acaras may occasionally uproot plants, so anchor them well or use hardy species.
Filtration
Use a quality canister or hang-on-back filter rated for at least 2x your tank volume per hour. Blue Acaras appreciate clean, well-oxygenated water. Perform 25–30% water changes weekly.
Diet & Feeding
Blue Acaras are omnivores with a hearty appetite. A varied diet keeps them healthy and enhances their coloration:
- Staple: High-quality cichlid pellets or flakes
- Protein: Frozen or live bloodworms, brine shrimp, earthworms, and krill
- Vegetables: Blanched spinach, zucchini, or peas (occasional treat)
Feed 1–2 times daily, offering only what they can consume in 2–3 minutes. Remove any uneaten food to maintain water quality.
Tank Mates
Blue Acaras are one of the more community-friendly cichlids, but choose tank mates carefully:
Good Tank Mates
- Other South American cichlids (Severums, Geophagus, Keyhole Cichlids)
- Larger tetras (Congo Tetras, Buenos Aires Tetras)
- Rainbowfish
- Corydoras catfish
- Plecos and other armored catfish
Avoid
- Very small fish that may be seen as prey
- Aggressive cichlids (Oscars, Jack Dempseys, Flowerhorns)
- Fin-nipping species (Tiger Barbs)
Breeding
Blue Acaras are open spawners and relatively easy to breed in captivity. They form monogamous pairs and are attentive parents. To encourage spawning:
- Condition the pair with high-protein live or frozen foods
- Provide flat rocks or broad leaves as spawning sites
- Slightly raise the water temperature to 80–82°F
The female will lay 150–300 eggs, which both parents guard fiercely. Fry become free-swimming within 5–7 days and can be fed baby brine shrimp or finely crushed flake food.
Common Health Issues
- Ich (White Spot): Caused by stress or poor water quality. Treat with aquarium salt or ich medication and raise temperature slightly.
- Hole-in-the-Head Disease: Associated with poor diet and water quality. Improve diet and perform more frequent water changes.
- Bloat: Often caused by overfeeding or low-quality food. Feed a varied diet and avoid overfeeding.
Final Tips
- Blue Acaras are intelligent and will recognize their owner over time — a truly interactive fish
- Their color intensifies with age, good diet, and clean water
- A well-decorated tank with hiding spots makes them more confident and colorful
- Avoid sudden changes in water parameters — stability is key
