Freshwater Angelfish Mix (Pterophyllum scalare)

01 October 2026

506

Freshwater angelfish are tall-bodied South American cichlids valued for their graceful movement and wide range of captive color forms. The supplied source identifies a mixed group as Pterophyllum scalare; the photographs show several forms, including striped, black, orange, white, silver and blue-toned fish. They are manageable for experienced beginners, but their adult height, territorial breeding behavior and tendency to eat small tank mates require thoughtful aquarium planning.

Freshwater Angelfish Mix (Pterophyllum scalare)

Taxonomy and identification

Pterophyllum scalare belongs to the family Cichlidae and genus Pterophyllum. It has a laterally compressed, disc-shaped body with elongated dorsal and anal fins and filamentous pelvic fins. The exact commercial varieties in this mixed source cannot be determined from the listing alone. The images represent multiple captive color and pattern forms rather than one reliably identifiable strain.

Native distribution and habitat

The species is native to slow-moving freshwater habitats in tropical South America, especially the Amazon Basin and associated tributaries. It occurs among submerged roots, branches and aquatic vegetation, where a deep body and tall fins help it maneuver through structured habitats. Captive aquariums should provide cover while leaving open swimming space.

Behavior

Angelfish are generally active, observant cichlids that use the middle and upper parts of the aquarium. Young fish may school loosely, but adults form territories and pairs. Courtship and spawning can make them substantially more defensive. They may also prey on fish small enough to fit in their mouths, particularly at night or when the smaller fish are resting.

Aquarium size and setup

For two adult angelfish, a well-filtered aquarium of about 200 litres is a practical starting point, with at least 45-50 cm of water height. A larger aquarium is preferable for a group or a community containing other substantial fish. Use smooth plants, vertical wood or other cover, gentle to moderate circulation and a secure lid. Maintain stable biological filtration and perform regular partial water changes.

Water parameters

Keep the water warm, clean and stable at 24-30 °C, with a pH of 6.0-7.5. Angelfish can adapt to moderately soft through moderately hard water when acclimated gradually, but sudden changes and detectable ammonia or nitrite should be avoided. Stability, oxygenation and low organic waste are more important than pursuing a narrowly defined numerical value.

Diet

Offer a varied diet based on a quality cichlid or tropical pellet, supplemented with frozen or live foods such as brine shrimp, bloodworms and mosquito larvae where appropriate. Feed small portions once or twice daily, removing uneaten food. Occasional vegetable matter can add variety, but a balanced prepared food should remain the dietary foundation.

Compatibility

Choose peaceful to moderately assertive tank mates that are too large to be swallowed and that tolerate warm water. Suitable choices may include robust small-to-medium tetras, peaceful barbs selected carefully, Corydoras species of suitable size and some peaceful South American cichlids. Avoid fin-nipping species, highly aggressive cichlids and very small fish or shrimp. Monitor aggression because individual angelfish differ considerably.

Breeding

Angelfish form pairs and usually spawn on a clean, broad vertical surface such as a plant leaf, slate or aquarium panel. The pair cleans the site, the female lays rows of adhesive eggs and the male fertilizes them. Both parents may fan and defend the clutch, although inexperienced pairs sometimes eat eggs. For reliable rearing, use a separate breeding aquarium or remove the eggs to a clean, gently aerated setup. Fry require appropriately sized first foods once free-swimming and frequent small water changes.

Red Jewel Cichlid (Hemichromis lifalili)

Moderate - Difficult

African riverine cichlid

Hemichromis lifalili, commonly called the red jewel cichlid, is a small but strongly territorial African cichlid recognized for its red body, blue-green spotting and dark lateral markings. It is often confused in the aquarium trade with related Hemichromis species, especially H. bimaculatus, so identification from photographs or trade labels is not always certain. A pair needs a carefully arranged aquarium, stable water quality and a plan for managing aggression during breeding.
Redhump Eartheater (Geophagus steindachneri)

Moderate

South American eartheater cichlid

Geophagus steindachneri is a South American eartheater distinguished by its sloping forehead, browsing mouth and habit of sifting fine substrate for food. Adults become substantial, active cichlids that need generous floor space, clean water and a soft sand bed. The supplied fish are identified as Redhump Eartheaters, but locality and sex cannot be confirmed from the listing alone. They are generally peaceful for their size, though territorial behavior increases during spawning.
Rachow's Splendour Ground Carp (Nothobranchius rachovii)

Moderate - Difficult

Annual killifish

Rachow's splendour ground carp is a brightly marked annual killifish from seasonal freshwater habitats in Mozambique. Males display intense orange, red, blue and white coloration, while females are usually much plainer. It is best maintained in a species-focused aquarium with gentle filtration, a covered top and soft spawning material. The fish has a short natural lifespan, but careful feeding and egg management make it a rewarding specialist species. Aquarium specimens may represent different geographic forms, so locality information is valuable when available.
Red Tiger Oscar Cichlid (Astronotus ocellatus)

Difficult

Large South American cichlid

The Red Tiger Oscar is a selectively bred color form of Astronotus ocellatus, a large South American cichlid known for intelligence, bold feeding behavior, and strong individual personality. The supplied source describes a pair, but sex and true pair-bond status cannot be confirmed from the images alone. Oscars require a spacious, strongly filtered aquarium, careful tankmate selection, and a varied diet. They are rewarding display fish, but their adult size, territorial behavior, waste production, and tendency to rearrange décor make them unsuitable for most community aquariums.
Red Oscar Cichlid (Astronotus ocellatus)

Difficult

Large South American cichlid

The red Oscar is a selectively bred color form of Astronotus ocellatus, a large South American cichlid valued for its intelligence, interactive behavior, and bold appearance.
