by Rahim Mohamed 06 Jun 2024

Symphysodon aequifasciatus, commonly known as the Discus fish, is a stunning and sought-after fish species. Known for its vibrant colors and striking patterns, this fish is highly regarded by aquarium enthusiasts and collectors alike and is considered the King of the aquarium for freshwater fish.


Symphysodon aequifasciatus boasts a remarkable combination of colors and markings. The dominant coloration ranges from deep reds and oranges to vibrant blues and greens, creating a captivating display of colors that make it a standout species in any aquarium.

Size and Shape

Like all discus fish, they have a laterally compressed body with a round shape. They can grow to a size of around 6 to 8 inches (15 to 20 centimeters) in diameter, making them medium-sized fish suitable for larger aquarium setups.

Behavior and Care

Discus fish are known for their peaceful temperament, making them an excellent choice for community aquariums. However, it is important to note that discus fish require specific care to thrive.

Water Parameters

Maintaining optimal water conditions is crucial for the health and well-being of the Symphysodon aequifasciatus. They prefer slightly acidic to neutral water with a pH range of 6.0 to 7.0. This is mainly for wild-caught specimens, as most farm-raised specimens are more adaptable to a wide range of water parameters. The water temperature should be maintained between 82 to 86 degrees Fahrenheit (28 to 30 degrees Celsius). Additionally, regular water changes and a high-quality filtration system are essential to keep the water pristine and free from pollutants.


A varied and nutritious diet is vital for the Symphysodon aequifasciatus. They are omnivorous and will readily accept high-quality flake or pellet food, supplemented with frozen or live foods such as bloodworms, brine shrimp, and daphnia on occasion. Providing a balanced diet rich in protein will promote their vibrant coloration and overall health.

Aquarium Setup

To create an optimal environment for the Symphysodon aequifasciatus, it is recommended to provide a spacious aquarium with plenty of swimming space. The tank should be heavily planted with a mix of live and artificial plants to mimic their natural habitat and provide hiding spots. Soft substrate like sand or fine gravel is preferable to prevent any potential injuries to their delicate fins.


When selecting tankmates for the Symphysodon aequifasciatus, it is important to choose peaceful species that share similar water requirements. Suitable companions include peaceful tetras, rasboras, dwarf cichlids, and other non-aggressive fish that won't compete for food or harass the discus.


The Symphysodon aequifasciatus is a visually captivating fish with its vibrant colors and distinctive patterns. With the right care and attention to water parameters, diet, and tank setup, this beautiful discus can thrive and become the centerpiece of any aquarium.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
