Full Care Guide

Freshwater Angelfish Care: Pterophyllum scalare

Freshwater angelfish are tall South American cichlids, not small community fish. OATA gives 120 litres as an industry floor for a compatible pair and says the aquarium must be sufficiently tall. We prefer planning around roughly 200 litres, a 100 × 40 cm footprint and about 50 cm height for an adult pair, with more space and an exit plan for a group.

Overview

Rio Tocantins Angelfish is a locality/trade form of freshwater angelfish, best treated as Pterophyllum scalare rather than a separate species named "Pterophyllum Scalare Rio Tocantins".

Angelfish are elegant South American cichlids that need height, stable tropical water and thoughtful tank mates. They are peaceful compared with many cichlids, but they still have cichlid instincts and may eat very small fish once grown.

Quick facts

Adult size	Up to around 15 cm long, much taller with fins
Care level	Moderate
Minimum aquarium	160 litres or larger, with good height

pH	6.0-8.0
Temperament	Generally peaceful, territorial when pairing

Aquarium setup

Use a tall, mature aquarium with gentle flow, vertical wood or plants and open swimming space. Amazon swords, Vallisneria, broad-leaved plants and branchy wood suit the body shape and behaviour of angelfish. Avoid cramped tanks, harsh current and sharp decor that can damage trailing fins.

Feeding

Feed quality cichlid granules or flakes with frozen brine shrimp, daphnia, bloodworm in moderation and other small foods. Offer modest portions so slower angelfish are not outcompeted and water quality stays clean.

Compatibility

Good companions include peaceful medium tetras, Corydoras, dwarf cichlids with care, peaceful plecos and other calm fish too large to swallow. Avoid fin nippers, aggressive cichlids and tiny fish such as very small tetras or fry.
