Angelfish come in both freshwater and saltwater varieties, but the commonly kept aquarium angelfish (Pterophyllum species) are freshwater fish native to the Amazon River basin in South America.

Freshwater angelfish typically grow up to 6 inches in body length and can reach 8 inches tall including fins, depending on the variety and tank conditions.

With proper care, freshwater angelfish can live 8 to 10 years in captivity, and sometimes longer in well-maintained aquariums.

Freshwater angelfish are omnivores. In captivity, they eat flakes, pellets, frozen or live foods like brine shrimp and bloodworms. In the wild, they feed on small invertebrates, insect larvae, and plant matter.

Angelfish are semi-aggressive. While generally peaceful, they may display territorial behavior—especially during breeding or in crowded tanks.

It’s not recommended. Goldfish prefer cooler water, while angelfish need warm, tropical conditions. Their different care needs make them incompatible tank mates.

To breed angelfish, provide a bonded pair, warm water (78–82°F), and a vertical spawning surface like a leaf or slate. The pair will lay eggs, which they often guard until hatching in 2–3 days.

Keep angelfish in a tall tank (20+ gallons), maintain stable warm water (76–82°F), pH 6.5–7.5, and feed a varied diet. Add plants and vertical structures for hiding and territory.

Sexing angelfish is tricky. Males may have a larger forehead hump, while females often show a rounder belly. During breeding, males have a pointed breeding tube, and females have a blunt one.

Freshwater angelfish are native to the Amazon River basin and its tributaries in South America, where they inhabit slow-moving, warm freshwater with dense vegetation.

A white, fuzzy biofilm often appears on new driftwood. It's harmless, natural, and usually eaten by shrimp or fish; it disappears over time.

Compatible tank mates include peaceful species like corydoras, tetras (larger varieties), gouramis, and bristlenose plecos. Avoid fin-nippers or very small fish that may get eaten.

Angelfish form monogamous pairs during breeding and may stay bonded for life, especially in stable tank environments.

Aquarium driftwood is expensive due to careful sourcing, cleaning, curing, and shipping. Each piece is unique, making it a premium aquascaping material.

Leopold's angelfish (Pterophyllum leopoldi) is the smallest species, typically reaching 3 inches in body length and less commonly kept in aquariums.

Angelfish grow quickly in the first 6 months and usually reach adult size within 10–12 months, depending on diet and tank conditions.

Angelfish can be kept in groups of 4–6 in larger tanks (30+ gallons), but monitor for aggression. A single pair is ideal for smaller tanks.

Yes, freshwater angelfish are relatively easy to care for, making them a popular choice for intermediate aquarists.
