Angelfish

Environment

Due to its height (up to 15 cm without fins) and adult size, it requires a tall aquarium of at least 200 liters. Maintain water between 24 and 28°C, pH 6 to 7.5, with tall plants and vertical roots evoking its biotope. A group of 5 to 6 individuals helps dilute tensions.

Feeding

Omnivorous with carnivorous tendencies, it enjoys pellets, flakes, and live or frozen meaty prey (bloodworms, brine shrimp, krill). Vary the diet to preserve its colors and shape. Feed at regular times.

Health & common diseases

Angelfish are susceptible to white spot disease (ichthyophthirius), fin rot, and parasitic infections such as intestinal worms (hexamita), particularly when stressed. Watch for frayed fins, white spots on the body, weight loss, or holes in the head (hole-in-the-head disease). Quality water (nitrites at 0, stable temperature 24-28°C), a varied diet, and avoiding overcrowding prevent most diseases. Angelfish are also vulnerable to fungal infections after injuries or territorial fights.

Tips & tankmates

Common mistake: pairing them with neon tetras or other small fish, which they will eventually swallow once adult. Also avoid fin-nipping species and those with large fins (which they may also nibble, e.g., guppies). During spawning, a pair can become aggressive toward conspecifics and defend their territory.
