Proper care is essential to ensure your Marble Angelfish thrives in its aquarium environment. Below are some essential care guidelines to follow:

1. Water Quality & Temperature

   • Water Type: Marble Angelfish thrive in clean, soft freshwater. It's essential to maintain the right water conditions to avoid any stress or illness. Ensure your aquarium water is free of chlorine and chemicals. Use a water conditioner if using tap water.
   • Temperature: The ideal water temperature for Marble Angelfish is between 24-28°C (75-82°F). Sudden fluctuations in water temperature can cause stress, so it's crucial to maintain a stable environment.
   • Water pH: The preferred pH level for Marble Angelfish is between 6.0 and 7.5. Regular water testing is essential to ensure these parameters remain stable.

2. Tank Size & Setup

   • Tank Size: For a single pair of Marble Angelfish, a minimum tank size of 20 gallons (75 liters) is required. If you plan to keep multiple angelfish, larger tanks are necessary.
   • Tank Setup: These fish appreciate a well-planted tank with plenty of hiding spots. Plants like Java fern, Amazon sword, and Vallisneria work well in their habitat. Provide flat surfaces such as leaves or rocks where the fish can lay their eggs.
   • Filtration: Proper filtration is a must for maintaining clean water. Angelfish can be sensitive to poor water quality, so use a reliable filter that maintains water clarity while not creating too strong of a current.

3. Tank Mates & Compatibility

   • Peaceful Fish: Marble Angelfish are best kept with other peaceful fish species. Suitable companions include tetras, guppies, corydoras catfish, and other non-aggressive species.
   • Avoid Aggressive Fish: Avoid keeping angelfish with aggressive species, such as large cichlids, as they may bully or harm the angelfish.

4. Diet

   • Diet: Marble Angelfish are omnivores and enjoy a varied diet, including high-quality pellets, flakes, frozen or live food like brine shrimp, bloodworms, and daphnia. A balanced diet helps maintain their health and enhances their color vibrancy.
   • Feeding Frequency: Feed your Marble Angelfish once or twice a day. Only offer as much food as the fish can consume in 2-3 minutes to avoid water contamination.

5. Common Health Issues

   • Ich (White Spot Disease): This parasitic infection is common in angelfish and can be identified by white spots on the body. It can be treated by raising the water temperature slightly and adding salt to the aquarium.
   • Fin Rot & Fungal Infections: Poor water conditions can lead to fin rot and fungal infections. Ensure regular water changes and proper filtration to prevent these issues.
   • Skin Parasites: Marble Angelfish can be susceptible to skin parasites, especially when stressed or in poor water conditions. Treat with medications as advised by a veterinarian or aquatic specialist.

6. Breeding

   • Breeding Setup: Marble Angelfish are relatively easy to breed, but they require stable water conditions. A breeding pair will typically lay eggs on flat surfaces such as plants or rocks. Male and female fish will work together to care for the eggs until they hatch.
   • Egg Care: After fertilization, the parents protect and fan the eggs, ensuring proper oxygenation. Once the eggs hatch, fry should be fed finely crushed fish food.
