6 Koi Angel Fish Myths You Shouldn't Believe

Koi Angel Fish are admired for their striking colours and elegant fins, making them a favourite among aquarium enthusiasts. However, like many popular fish, myths surround these beauties, leading to misconceptions that can affect how people care for them. If you’re interested in keeping Koi Angels or already have a few in your tank, you may have come across some surprising claims. But are they true? Let’s dive into six common myths about Koi Angel Fish and uncover the facts to help you provide the best care for these stunning fish.

Myth 1: Koi Angel Fish Are Just Like Other Angelfish

While Koi Angels are part of the angelfish family, they stand out with their distinct orange, white, and black colouring, reminiscent of koi carp. This unique appearance often leads to the assumption that they share identical behaviours and needs with other angelfish. However, Koi Angels can be more territorial and aggressive, particularly in crowded tanks.

If you’re considering adding Koi Angels to your aquarium, it’s essential to provide them with ample space to maintain a peaceful environment. For a range of high-quality fish, including Koi Angels, check out our collection and visit your local stockist for tank essentials tailored to their unique needs.

Myth 2: Koi Angel Fish Are Easy to Care For

Koi Angels are hardy, but that doesn’t make them low-maintenance. They require clean water with a slightly acidic to neutral pH and thrive in stable temperatures between 24-28°C. Maintaining consistent water quality is vital to their health, so they’re not as “easy” as some might think.

To keep your Koi Angels healthy, you’ll need to regularly monitor water conditions and carefully choose compatible tank mates. Purchase your fish through our trusted stockists, who can also provide all the supplies you need for creating an ideal aquarium environment.

Myth 3: Koi Angel Fish Only Thrive in Freshwater

It’s a common misconception that Koi Angels can only survive in strictly freshwater conditions. While they are freshwater fish, they can adapt to slightly brackish water with gradual adjustments. This doesn’t mean they should live in highly saline tanks, but they can tolerate minor fluctuations in water conditions.

This adaptability makes them suitable for areas with harder or slightly salty water. Visit your local stockist to find the right water treatments to maintain an ideal environment for your Koi Angels.

Myth 4: Koi Angel Fish Can Be Kept with Any Tank Mates

The idea that Koi Angels get along with any fish can lead to unfortunate conflicts. Koi Angels are semi-aggressive and may not mix well with smaller fish or species with long fins, like guppies. They thrive best with tank mates of a similar size and temperament, such as medium-sized cichlids or larger tetras.

If you’re planning a community tank, choose compatible fish to avoid stress or aggression. Our stockists can help you select the best combinations to create a harmonious aquarium.

Myth 5: Koi Angel Fish Don’t Breed in Captivity

This myth is far from true! Koi Angels can and do breed in home aquariums. With the right conditions—such as a peaceful environment and a large enough tank—Koi Angels will pair up and lay eggs on flat surfaces. However, their eggs and fry are delicate, requiring careful attention to thrive.

If breeding Koi Angels is your goal, consider setting up a separate breeding tank or optimising your current tank. Visit your local stockist for the necessary supplies to support a successful breeding setup.

Myth 6: Koi Angel Fish Can Survive in Small Tanks

Some believe Koi Angels can thrive in small tanks due to their relatively smaller size. However, these fish require ample swimming space and hiding spots to feel secure. Tanks that are too small can lead to stress, which increases the risk of illness or aggression. A tank of at least 115 litres (30 gallons) is recommended, with larger tanks ideal for groups.

Check with your local stockist to ensure you’re purchasing a tank that meets the needs of Koi Angels and other fish.

Bottom Line

Debunking these myths can make a world of difference in providing the right care for your Koi Angel Fish. These vibrant and unique fish deserve a well-maintained environment, free from common misconceptions. Whether you’re new to fishkeeping or a seasoned aquarist, understanding their needs will ensure a fulfilling and enjoyable experience.
