Tank Setup
The Electric Blue Acara (Andinoacara pulcher) requires a minimum tank size of 30 gal. For a species this size, a larger tank is always better — more water volume means more stable parameters and a healthier environment.
Water parameters should be maintained within the following ranges: temperature 24–28°C, pH 6.0–7.5, and hardness 4–15 dGH. These are relatively tolerant fish that adapt to a range of conditions.
Provide appropriate hiding places, a suitable substrate, and planted areas to match the natural behaviour of this species.
Tank Mates
Electric Blue Acara are semi-aggressive fish. Choose tankmates carefully — they may not be suitable for all community setups.
Compatible tank mates include: Corydoras, Bristlenose Pleco, Severum, Larger Tetras, Rainbowfish. Always ensure all species share similar water parameter requirements before mixing.
Schooling requirements: Pairs.
Diet & Feeding
Electric Blue Acara are Omnivore. Feed a varied diet to ensure optimal health and colouration.
Omnivore — pellets, frozen bloodworm, brine shrimp, algae
Feed small amounts 1–2 times daily. Only provide what the fish can consume within 2–3 minutes to prevent overfeeding and water quality issues. Supplement with live or frozen foods for optimal health and colour.
Common Health Issues
Like all aquarium fish, Electric Blue Acara can be susceptible to common diseases including ich (white spot disease), fin rot, and bacterial infections. This species is generally hardy and disease-resistant when kept in good conditions.
Prevention is always better than treatment. Maintain stable water parameters, avoid overfeeding, quarantine new fish before adding them to the main tank, and perform regular water changes. A regular maintenance routine will prevent most health issues.
If disease does occur, isolate affected fish in a quarantine tank and treat appropriately. Always research medication compatibility before use — some treatments are toxic to invertebrates and scaleless fish.
Breeding
Breeding Electric Blue Acara is possible in the home aquarium.
Provide appropriate breeding conditions — caves or hiding places for egg-laying species. Condition breeding pairs with high-quality foods before attempting to spawn them.
Many Electric Blue Acara will breed readily without intervention. Be prepared to remove eggs or fry if you want to raise them — adult fish may eat their own young.
