Native to the Amazon Basin, Pterophyllum scalare is typically found in slow-moving waters with dense vegetation. In the aquarium, Blue Marble Angelfish display a peaceful yet semi-territorial nature, especially during breeding. They are active mid to upper-level swimmers, gracefully navigating their environment.
2. Aquarium Setup
- Tank Size: A minimum of 20 gallons for a pair, with 40 gallons or more recommended for groups.
- Substrate: Soft sand or smooth gravel replicates their natural environment.
- Decor: Include tall plants, driftwood, and rock structures to provide hiding spots and visual appeal.
- Water Conditions: Maintain a temperature of 75-82°F (24-28°C), a pH of 6.0-7.5, and soft to moderately hard water (3-10 dGH).
- Lighting: Moderate lighting enhances their blue coloration without stressing them.
3. Diet and Feeding
Blue Marble Angelfish are omnivorous and benefit from a varied diet:
