Caring for freshwater angelfish is a rewarding experience, but they have specific needs that set them apart from typical community fish. Because they are cichlids, they can be semi-aggressive and grow quite large, so a thoughtful setup is key to a healthy aquarium.
Tank Requirements
Angelfish are tall, not long, so tank height is more important than length.
· Tank Size: Minimum 30 gallons for a single pair, but 55 gallons or larger is highly recommended for a community or a small group. For a group of 6+, aim for 75+ gallons to reduce aggression.
· Tank Shape: A tall aquarium (at least 18-20 inches / 45-50 cm high) is essential to accommodate their long fins.
· Aquascape: Use gentle filtration and provide vertical driftwood, tall plants (like Amazon Swords or Vallisneria), and smooth rocks. This mimics their natural habitat
