Tank Size and Setup

  • Tank Size: A minimum tank size of 55 gallons (208 liters) is recommended for a small group of Yellow Marlboro Discus.
  • Substrate: A fine-grained substrate, such as sand or small gravel, is ideal for these fish as they like to sift through it for food.

Water Parameters

  • Temperature: Maintain the water temperature between 82°F and 86°F (28°C and 30°C).

Filtration and Maintenance

Nutrition and Diet for Yellow Marlboro Discus

Providing a balanced and nutritious diet is crucial for the health and vitality of your Yellow Marlboro Discus. These fish are omnivorous and require a varied diet to meet their nutritional needs.

Types of Food

  • Live Foods: Offer live foods, such as brine shrimp, daphnia, and bloodworms, as a treat. Live foods provide essential nutrients and stimulate the fish’s natural hunting instincts.
  • Frozen Foods: Frozen foods, such as frozen brine shrimp, mysis shrimp, and krill, are a convenient and nutritious alternative to live foods.
  • Commercial Foods: High-quality commercial foods specifically formulated for discus are also a good option. Look for foods that are rich in proteins, vitamins, and minerals.

Feeding Schedule

  • Frequency: Feed your Yellow Marlboro Discus several small meals throughout the day, rather than one large meal. This helps prevent overfeeding and keeps the water quality stable.
  • Quantity: Offer enough food so that the fish can consume it within a few minutes. Avoid overfeeding, as this can lead to water quality issues and health problems.

Breeding Yellow Marlboro Discus

Breeding Yellow Marlboro Discus can be a rewarding experience for experienced aquarists. However, it requires careful planning, preparation, and attention to detail to ensure successful breeding.

Selecting Breeding Pairs

  • Compatibility: Choose breeding pairs that are compatible in terms of size, temperament, and coloration.
  • Age: Select breeding pairs that are sexually mature, typically around 12-18 months old.
  • Health: Ensure that the breeding pairs are healthy and free from any diseases or parasites.

Breeding Tank Setup

  • Tank Size: Use a separate breeding tank that is at least 40 gallons (151 liters) in size.
  • Substrate: Provide a fine-grained substrate, such as sand or small gravel, to allow the eggs to adhere.

Breeding Process

  • Conditioning: Condition the breeding pairs by providing a high-quality diet and maintaining optimal water conditions.
