Angelfish Beginner Care FAQ

Q: How big of a tank do I need for angelfish?
A: You’ll need at least 30 gallons for a single pair. Because angelfish can reach up to 6" long and 8" tall with their fins, your tank should also be at least 16" tall.

Q: Are freshwater angelfish the same as saltwater angelfish?
A: No. Freshwater angelfish are part of the cichlid family, while saltwater angelfish belong to a completely different group.

Q: What types of freshwater angelfish are available?
A: Popular varieties include wild type (silver with black stripes), koi (red/orange/white/black), marble (black, white, and silver pattern), plus black, albino, platinum, and GloFish® angelfish.

Q: Should I keep one, a pair, or a group?
A: Beginners often find it easiest to keep a single angelfish or a pair. While they are schooling fish, angelfish are also cichlids and can get territorial during breeding season, so groups require larger tanks and careful management.

Q: What’s the best temperature and pH for angelfish?
A: Keep them around 76–78°F (though they tolerate up to 85°F). This reduces aggressive behavior. pH can range from 6.0–8.0, and they adapt to both soft and hard water.

Q: How should I set up the tank?
A: Use tall, leafy plants like Amazon swords and Java ferns. Provide open swimming space and avoid sharp decorations, as their long fins can tear easily.

Q: What do angelfish eat?
A: They eat a wide variety of foods: flakes, frozen mysis shrimp, brine shrimp, and bloodworms. Feed a varied diet to avoid nutrient deficiencies.

Q: What are good tank mates for angelfish?
A: Suitable companions include plecos, corydoras, and many types of tetras. Avoid fin-nippers like tiger barbs and tiny fish that could be eaten. Also, don’t pair them with cold-water species like shrimp or axolotls.
