Orange Koi Angelfish – Pterophyllum scalare
The Orange Koi Angelfish, scientifically known as Pterophyllum scalare, is a colorful freshwater angelfish variety known for its bright orange, white, yellow, and black marbled patterning. Each fish has a unique combination of colors and markings, making Orange Koi Angelfish an attractive centerpiece for planted aquariums and larger freshwater community setups.
Orange Koi Angelfish are generally graceful and peaceful, but they may become territorial as they mature or when a pair begins spawning. They should be kept with appropriately sized tankmates that will not nip their long fins or be small enough to be viewed as food.

Feeding
Orange Koi Angelfish are omnivores and should receive a varied diet. Feed a quality tropical flake, small pellet, or cichlid food as the primary diet. Supplement with frozen or live foods such as brine shrimp, bloodworms, daphnia, or mysis shrimp when appropriate.
Offer only what the fish can consume within a few minutes and remove uneaten food. A balanced diet can help support healthy growth, strong coloration, and proper fin development.
Compatible Tankmates
- Medium-sized peaceful community fish
- Larger tetras that are not known for fin nipping
- Corydoras catfish
- Peaceful plecos and other compatible bottom dwellers
- Gouramis with suitable temperaments
- Other angelfish in a properly sized aquarium
Avoid keeping Orange Koi Angelfish with aggressive cichlids, known fin nippers, or very small fish that may eventually be viewed as food. Compatibility depends on aquarium size, individual temperament, group structure, and the amount of available territory.
Orange Koi Angelfish Care Tips
- Use a tall aquarium that provides room for the fish’s full fin height
- Keep water temperature and parameters stable
- Provide plants and vertical decorations for cover
- Avoid sharp decorations that may damage long fins
- Select tankmates that will not nip fins or harass the angelfish
- Feed a varied diet of prepared, frozen, and occasional live foods
- Monitor ammonia, nitrite, nitrate, pH, and water temperature
- Perform regular water changes to maintain good water quality
Important Aquarium Care Note
Orange Koi Angelfish are cichlids and may become territorial as they mature. Breeding pairs can defend a section of the aquarium and may chase other fish away from eggs or fry. Providing adequate space, visual barriers, and hiding areas can help reduce conflict.
Small fish such as tiny tetras or juvenile livebearers may be eaten by adult angelfish. Choose tankmates based on their adult size and behavior rather than their size at the time of purchase.
