How Are Discus as Pets?

Discus fish are elegant and captivating pets that can add a touch of beauty and sophistication to your aquarium.

Discus Habitat and Tank Setup

Appropriate Discus TankSize and Type

A minimum tank size of 55 gallons is recommended for Discus, with larger tanks being even better for a group of fish. A taller tank is preferable, as Discus are vertically-oriented swimmers. It’s essential to provide ample swimming space and hiding spots for these fish to feel comfortable and secure.

Discus Water Temperature and Quality

Discus fish require warm water, with temperatures between 82-86°F (28-30°C). A heater is necessary to maintain a stable temperature. Additionally, the water should be soft and slightly acidic, with a pH between 6.0 and 7.0. Regular water changes and monitoring of water parameters are essential to ensure optimal water conditions.

Filtration and Aeration Requirements

A high-quality filter is essential for maintaining a clean and healthy environment for Discus. A canister filter is recommended due to its efficiency and ability to handle large volumes of water. Proper aeration is also crucial, as Discus fish need well-oxygenated water. An air pump with an air stone can provide adequate aeration.

Lighting Requirements

Discus fish do not have specific lighting requirements, but a standard aquarium light with a timer set to mimic a natural day/night cycle will help create a comfortable environment. Avoid placing the tank in direct sunlight, as it can cause temperature fluctuations and promote algae growth.

Plants for Discus

Live plants can help improve water quality and provide hiding spots for Discus. Some suitable plant species include Amazon sword, Java fern, and Anubias. Be sure to choose plants that can tolerate the warm water temperatures required by Discus fish.

Substrate, Hideouts, and Decorations

A soft, sandy substrate is ideal for Discus, as it will not harm their delicate fins. Provide hiding spots using driftwood, rocks, or ceramic decorations. However, make sure to leave plenty of swimming space for these active fish.

Aquarium Cleaning and Maintenance

Regular water changes, filter maintenance, and cleaning of decorations are vital for maintaining a healthy environment for Discus. Aim to change 25-30% of the water weekly and clean the filter media regularly to remove debris and maintain efficiency.

Discus Food and Diet

What Do Discus Eat?

Discus are omnivorous and require a varied diet to stay healthy. High-quality pellets or flakes specifically formulated for Discus should form the basis of their diet. Supplement with frozen or live foods such as brine shrimp, bloodworms, and daphnia to provide additional nutrients and variety.

Feeding Frequency and Schedule

Feed your Discus 2-3 times per day, providing only enough food that they can consume within a few minutes. Be careful not to overfeed, as this can lead to poor water quality and health issues for your fish.

Discus Treats

Occasionally offering treats such as blanched spinach, peas, or cucumber can provide additional nutrients and enrichment for your Discus. Be sure to remove any uneaten treats after a few hours to prevent water quality issues.
