🚫 Do Not Mix

Goldfish and Angelfish have fundamentally incompatible requirements. Goldfish are coldwater, messy, and produce high waste, while Angelfish are tropical, require pristine water, and are semi-aggressive. Their temperature, dietary, and behavioral needs are in direct conflict.

Potential Issues

•Goldfish require cooler water (65-72°F) which will stress and weaken Angelfish (78-84°F), making them prone to disease.
•Angelfish are known fin-nippers and will target the long, flowing fins of fancy goldfish.
•Goldfish are voracious eaters and will outcompete the more deliberate Angelfish for food.
•Goldfish produce a massive bioload, requiring a powerful filter; Angelfish are sensitive to poor water quality.
