Tank Setup
The Angelfish (Pterophyllum scalare) 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 24–30°C, pH 6.0–7.5, and hardness 3–8 dGH. These fish are sensitive to water quality — test regularly and maintain pristine conditions.
Provide appropriate hiding places, a suitable substrate, and planted areas to match the natural behaviour of this species.
Tank Mates
Angelfish are semi-aggressive fish. Choose tankmates carefully — they may not be suitable for all community setups.
Compatible tank mates include: Larger Tetras, Corydoras, Bristlenose Pleco, Pearl Gourami, Rummy Nose Tetra. Always ensure all species share similar water parameter requirements before mixing.
Schooling requirements: Pairs or groups of 6+ to distribute aggression. Keeping them in adequate numbers is essential for their wellbeing.
Diet & Feeding
Angelfish are Carnivore. Their diet should reflect their natural feeding habits.
Carnivore — pellets, frozen bloodworm, brine shrimp
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, Angelfish can be susceptible to common diseases including ich (white spot disease), fin rot, and bacterial infections. This species can be sensitive — maintain excellent water quality to prevent health issues.
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. Test your water weekly and address any parameter spikes immediately.
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 Angelfish requires specific conditions and may be challenging for beginners.
Provide appropriate breeding conditions — caves or hiding places for egg-laying species. Condition breeding pairs with high-quality foods before attempting to spawn them.
Research specific breeding requirements for this species before attempting it.
