Meet the Six Barred Angelfish: A Fish of Two Faces
The most fascinating thing about the six barred angelfish is its radical change in appearance from juvenile to adult. It’s like having two completely different fish in one lifetime!
As a juvenile, it’s a deep, dark blue-black color, decorated with striking vertical bars of white and light blue. They are often shy, preferring to stick close to the safety of rockwork. This appearance is a clever defense mechanism, helping them blend into the shadows of the Indo-Pacific reefs where they originate.
As the fish matures, an incredible transformation occurs. The dark background gives way to a beautiful tan or yellowish-cream body. The juvenile stripes are replaced by six distinct, dark vertical bars that give the fish its common name. The face develops a yellowish mask, and the tail fin becomes a canvas of brilliant blue spots. This adult is bold, inquisitive, and undeniably the king or queen of its domain.
This is not a small fish. A fully grown adult can reach up to 18 inches in length in the wild, though they typically top out around 10-12 inches in a home aquarium. With proper care, they can live for over a decade, making them a long-term commitment and a true member of your aquatic family.
The Ideal Home: Your Six Barred Angelfish Care Guide to Tank Setup
Creating the right environment is the single most important factor for success. This isn’t a fish you can squeeze into a small tank. This section of our six barred angelfish guide covers the essentials for building their perfect home.
Tank Size: Go Big or Go Home
Let’s be direct: the six barred angelfish needs a large aquarium. While a young juvenile might seem fine in a 75-gallon tank, it will quickly outgrow it. To ensure a healthy, low-stress life for an adult, you should be planning for a tank of 180 gallons or larger.
Why so big?
- Swimming Space: These are active swimmers that need room to roam and glide.
- Territory: A large tank reduces territorial aggression, allowing them to establish their own space without constantly harassing tank mates.
- Waste Dilution: As large fish, they produce a significant amount of waste. A larger water volume helps keep water parameters stable and clean.
Aquascape and Environment
Your aquascape should serve two purposes: providing security and allowing for open swimming. A generous amount of live rock is essential. Create plenty of caves, overhangs, and crevices where the angelfish can retreat to feel secure, especially when it’s young.
However, don’t overcrowd the tank. Be sure to leave large, open channels and areas in the middle and front of the aquarium for swimming. A mix of secure hiding spots and open water is the key to a confident and happy fish.
Water Parameters: The Keys to Health
Like most marine fish from reefs, the six barred angelfish requires stable, pristine water conditions. Drastic swings in water quality are a primary source of stress and disease. Here are the target parameters to aim for, which represent some of the most critical six barred angelfish best practices:
- Temperature: 74-82°F (23-28°C)
- Specific Gravity: 1.020-1.025
- pH: 8.1-8.4
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Nitrate: <20 ppm (as low as possible)
A high-quality protein skimmer is not optional; it’s a necessity to handle the biological load this fish will produce. Regular water changes (10-20% weekly or bi-weekly) are also crucial for maintaining low nitrate levels and replenishing trace elements.
Feeding Your Angelfish: A Varied Diet for Vibrant Health
Figuring out how to six barred angelfish should be fed is a common question, and the answer is variety! In the wild, their diet consists heavily of sponges and tunicates. Replicating this is vital for their long-term health and is one of the most important six barred angelfish tips we can offer.
Crafting the Perfect Aquarium Diet
A simple diet of flake food will not suffice. A healthy six barred angelfish requires a diverse menu that caters to its omnivorous, grazing nature.
- High-Quality Angelfish Formula: Start with a quality prepared food specifically formulated for marine angelfish. Look for brands that include sponge matter in their ingredients. This should be the staple of their diet.
- Meaty Foods: Supplement their diet with frozen foods like mysis shrimp, brine shrimp, and chopped krill or squid. These provide essential proteins and fats.
- Vegetable Matter: Offer dried seaweed (nori) on a feeding clip several times a week. You can also feed spirulina-enriched foods and other marine algae preparations.
Feeding small amounts two to three times per day is better than one large feeding. This mimics their natural grazing behavior and helps keep water quality high.
Temperament and Tank Mates: Creating a Peaceful Community
The six barred angelfish has a commanding presence, and its temperament matches its size. As adults, they are typically bold and can be quite territorial, especially towards other angelfish or fish with a similar body shape and color.
Choosing Compatible Tank Mates
Selecting the right neighbors is crucial for a harmonious tank. Here are some general guidelines:
- Good Choices: Larger, semi-aggressive fish are often the best fit. Think Tangs (like a Naso or Yellow Tang), large Wrasses (like a Coris or Harlequin Tusk), and some Triggerfish (like a Pink Tail or Niger). Always introduce the angelfish last or near last to reduce its territorial claims.
- Poor Choices: Avoid small, timid fish like firefish, gobies, and small clownfish, as they will likely be bullied. Keeping them with other large angelfish (from the Pomacanthus or Holacanthus genus) is only recommended for experts with exceptionally large systems (300+ gallons).
A Note on Reef Safety: “Reef Safe With Caution”
This is a critical point and one of the most common problems with six barred angelfish. They are not considered reef safe. While some individuals may leave corals alone, most will eventually nip at or consume fleshy Large Polyp Stony (LPS) corals, Small Polyp Stony (SPS) corals, and clam mantles. They may also pick at zoanthids and other soft corals.
If your dream is a pristine SPS-dominated reef tank, this is probably not the fish for you. However, they can often be kept successfully in a Fish-Only-With-Live-Rock (FOWLR) setup or with more noxious soft corals like leather corals or some mushrooms that they tend to ignore.
Common Problems with Six Barred Angelfish (And How to Solve Them)
Even with the best care, you might run into a few bumps in the road. Here’s how to navigate some common challenges.
Problem 1: Refusal to Eat
Newly introduced angelfish are often stressed and may refuse to eat for several days. This is common. Be patient and entice them with tempting foods. Soaking frozen mysis shrimp in a garlic supplement can often trigger a feeding response. Ensuring pristine water quality and providing plenty of hiding places will help them settle in faster.
Problem 2: Marine Ich and Other Parasites
Stress from shipping and acclimation can lower their immune system, making them susceptible to common parasites like Marine Ich (Cryptocaryon irritans) and Velvet (Amyloodinium ocellatum). The absolute best defense is a quarantine tank. Quarantining all new arrivals for 4-6 weeks allows you to observe them for disease and treat them in a separate system without contaminating your display tank.
Problem 3: Aggression
If your angelfish becomes a bully, first check your tank size. Aggression is often a symptom of being cramped. You can also try rearranging the rockwork to break up established territories. This “resets” the tank and can curb territorial behavior.
The Aquifarm Approach: Sustainable Six Barred Angelfish Best Practices
Being a responsible aquarist means thinking about the health of our oceans, too. Promoting a sustainable six barred angelfish hobby is a core part of our philosophy here at Aquifarm.
Choosing a Healthy, Ethically Sourced Fish
When you’re at your local fish store, look for a fish that is active, alert, and has clear eyes. Its body should be free of any spots, blemishes, or torn fins. Ask the store about their suppliers. Supporting retailers who partner with certified collectors ensures your fish was collected with minimal impact on the reef ecosystem. This is a cornerstone of an eco-friendly six barred angelfish experience.
The Importance of Quarantine
We mentioned it before, but it’s worth repeating. A quarantine tank is not just good for your fish; it’s a sustainable practice. Preventing a disease outbreak in your main tank means you avoid using harsh medications that can harm invertebrates and beneficial bacteria, and you prevent the tragic loss of livestock.
Long-Term Commitment
Remember, this is a large fish with a long lifespan. By purchasing a six barred angelfish, you are making a commitment to provide it with a proper home for a decade or more. This dedication is the ultimate form of responsible fishkeeping.
Frequently Asked Questions About the Six Barred Angelfish
How big do Six Barred Angelfish get?
In a home aquarium, you can expect them to reach an adult size of 10 to 12 inches (about 25-30 cm). They need a tank of at least 180 gallons to accommodate their size and active nature.
Are Six Barred Angelfish reef safe?
No, they are considered “reef safe with caution” at best. Most individuals will nip at and consume various types of corals (LPS, SPS) and clams. They are best suited for FOWLR (Fish-Only-With-Live-Rock) aquariums.
Can I keep more than one Six Barred Angelfish?
This is not recommended unless you have a massive aquarium (300+ gallons) and can acquire a mated pair. They are highly aggressive towards other angelfish, especially their own kind.
Are Six Barred Angelfish good for beginners?
We would classify them as a fish for a “dedicated beginner” or an intermediate hobbyist. While their care is straightforward, their requirements for a very large tank, a specific diet, and careful tank mate selection make them a more demanding choice than typical starter fish.
