Introduction:
Angelfish (Pterophyllum scalare) are among the most popular tropical fish species in the aquarium hobby, known for their graceful fins, vibrant colors, and engaging behavior. However, selecting suitable tank mates for these delicate creatures can be a daunting task. This comprehensive guide will provide you with everything you need to know about choosing the right tank mates for your angelfish, ensuring a harmonious and thriving aquarium environment.
Angelfish are generally peaceful and non-aggressive fish; however, they can become territorial and aggressive during certain circumstances, such as breeding or when they feel threatened. Therefore, it is crucial to select tank mates that are compatible with their temperament and behavior.
Factors to Consider:
Corydoras catfish are excellent bottom-dwelling companions for angelfish. They are small, peaceful fish that occupy the lower water levels, leaving the upper levels for the angelfish. Their scavenging behavior helps keep the tank clean.
Otocinclus catfish are another great choice for angelfish. These tiny fish are known for their algae-eating habits, which can help control algae growth in the tank. They are also very peaceful and unlikely to bother angelfish.
Small, schooling tetras can make lively and colorful companions for angelfish. Species such as neon tetras, cardinal tetras, and rummy nose tetras can provide a vibrant contrast to the larger, more stately angelfish.
Dwarf cichlids, such as apistogramma species, can be suitable tank mates for angelfish in larger tanks. These fish are generally peaceful and occupy different territories than angelfish, reducing potential conflicts.
Rainbowfish, such as neon rainbowfish or turquoise rainbowfish, are active, schooling fish that can add a pop of color to the tank. They are generally compatible with angelfish, as long as there is ample space for both species.
Aggressive species, such as tiger barbs, red-bellied piranhas, and Siamese fighting fish, should not be kept with angelfish. These fish can seriously injure or even kill angelfish.
Larger, predatory fish, such as oscars, cichlids, and arowanas, may consider angelfish as prey and pose a serious threat to their well-being. Avoid keeping these predators in the same tank as angelfish.
Avoid keeping fast-moving or overly active fish with angelfish. These fish can stress or intimidate angelfish, leading to aggression or illness.
Sarah had a 55-gallon aquarium with a group of angelfish. She decided to add a school of neon tetras for color and movement. However, the tetras quickly became stressed and harassed by the angelfish, even though they were much smaller. Sarah realized that the difference in size and temperament was too great, leading to compatibility issues.
John had a 20-gallon aquarium with a pair of angelfish. He wanted to add some bottom-dwelling fish for cleanup and variety. He purchased a few otocinclus catfish, which initially seemed to coexist peacefully with the angelfish. However, after a few weeks, John noticed that the angelfish were chasing the catfish, nipping at their fins. The otocinclus were becoming stressed and hiding in the aquarium decor.
Mary had a 75-gallon aquarium with a community of angelfish, tetras, and corydoras catfish. She noticed that her angelfish were behaving unusually. They were hiding in the plants and seemed lethargic. Mary tested the water parameters and realized that the pH had dropped below 6.5, which was causing stress to the angelfish. She adjusted the water chemistry and gradually increased the pH back to the optimal range. Within a few days, her angelfish returned to their usual playful and energetic behavior.
