About the Angelfish
The Angelfish (Pterophyllum scalare) is South America's most charismatic cichlid — the tall, sail-finned silhouette is iconic in planted aquariums worldwide. Captive lifespan runs 8–10 years with peak individuals reaching 15. The species is mid-water-column dwelling, mildly territorial (especially during pair-bond formation), and grows surprisingly large: a fully developed angelfish reaches 15 cm body length and 25 cm fin tip-to-tip, requiring tanks of 200 L minimum. Diet is omnivorous with a slight carnivore lean — quality flake plus frozen bloodworms or brine shrimp. Knowing your angelfish's human-equivalent age helps timing of breeding decisions (peak fertility year 2–5), and spotting the senior transition (typically year 8) when tank-mate compatibility changes. This calculator uses peer-reviewed aquarium veterinary data.
How Angelfishs age
Through life, a Angelfish moves through fry (0-3 mo) → juvenile (3-6 mo) → adult (6 mo-7 yr) → senior (7-15 yr); the early years carry the highest growth rate by a wide margin. Skeletal maturity, immune calibration, and behavioural shape are all set during the juvenile phase, which is why husbandry errors in the first years compound for life. Adulthood is the long stable plateau most owners enjoy, and the period where preventive care delivers the most return. Senior stage usually arrives at 70-80 % of average species lifespan — for this species, that is roughly age 8. Reaching the species' upper lifespan range typically depends on excellent nutrition, regular veterinary screening, and consistently meeting published husbandry guidelines.
Senior Angelfish care tips
- Minimum 200 L tank for a pair; tall profile to accommodate fin height.
- Omnivore diet: quality flake plus frozen bloodworms, brine shrimp, daphnia.
- Stable temperature 24-28 °C; pH 6.5-7.5; soft to moderately hard water.
- Strong filtration with low current; angelfish dislike strong flow.
- Stable tank-mates; avoid fin-nippers (tigers, certain barbs) and tiny prey-sized fish.
Common Angelfish health concerns
- Hexamita / hole-in-the-head
- Pitting around eyes and lateral line; improve water quality and consider metronidazole-medicated food.
- Ich during temperature swings
- Stable thermostat plus 28 °C-treatment routine prevents recurring ich.
- Aggression to small tankmates
- Adult angelfish predate on neons and small tetras; choose tank-mates of similar size.
