    Care Details
    • Aquascape: Create a natural-looking environment with plenty of hiding spots using plants, rocks, and driftwood to mimic their natural habitat.
    • Substrate: Choose a soft substrate like sand or smooth gravel to prevent injury to their delicate undersides.
    • Disease Prevention: Maintain excellent water quality through regular water changes and monitor for signs of common freshwater fish diseases. Quarantine new fish before introducing them to the main tank to prevent the spread of diseases.
    • Filtration: Use a high-quality filtration system to keep the water clean and free from toxins. Consider a combination of mechanical, biological, and chemical filtration to ensure optimal water quality.
    • Lighting: Provide moderate lighting to simulate natural daylight conditions. Avoid intense lighting, as Figure 8 Puffers prefer dimly lit environments.
    • Water Flow: Maintain gentle water flow to mimic their natural habitat. Avoid strong currents that may stress the fish.
    • Hardiness: Figure 8 Puffers are relatively hardy fish when kept in suitable conditions with stable water parameters.
    • Acclimation: When introducing Figure 8 Puffers to a new tank, acclimate them slowly to prevent stress and shock. Gradually adjust the water parameters over a period of time before releasing them into the main tank.
    • Expected Lifespan: With proper care, Figure 8 Puffers can live up to 5 years or more in captivity.
    • Special Requirements: Monitor their teeth growth, as they may need hard foods or snails to wear them down naturally. Provide a varied diet to ensure they receive essential nutrients. Keep tank mates compatible with their peaceful temperament to prevent aggression and stress.
    Temperament and Behavior
    • Behavior: Figure 8 Puffers are generally peaceful and curious fish, known for their intelligent behavior and playful nature. They often explore their surroundings and interact with objects in the tank.
    • Breeding: Breeding Figure 8 Puffers in captivity is challenging and rarely done in home aquariums. Little is known about their breeding habits in the wild, and successful breeding attempts in captivity are few and far between.
    • Aggression: While Figure 8 Puffers are typically peaceful, they can become aggressive towards conspecifics (other Figure 8 Puffers) or other tank mates if they feel threatened or stressed. Avoid keeping them with aggressive or territorial fish that may intimidate or harm them.
    • Tankmates Compatibility: Choose tank mates that are compatible with the peaceful temperament of Figure 8 Puffers. Avoid aggressive or territorial fish and opt for peaceful community fish or species that inhabit different areas of the tank.
    • Activity Level: Figure 8 Puffers are moderately active fish, spending much of their time exploring their environment and searching for food. They appreciate a tank with plenty of hiding spots and areas to explore.
    • Schooling or Shoaling Behavior: Figure 8 Puffers do not exhibit schooling or shoaling behavior and are generally solitary fish. They may tolerate conspecifics in larger tanks with plenty of hiding spots, but aggression can occur, especially during mating.
    • Plant Compatibility: Figure 8 Puffers may nip at or uproot plants in the aquarium, especially if they are not provided with enough hard surfaces to wear down their teeth. Choose hardy plants like Java fern, Anubias, or floating plants that can withstand their activity.
    Diet and Nutrition
    • Dry Foods: Offer high-quality dry foods specifically formulated for puffers, such as pellets or flakes. Ensure the food is appropriately sized for the fish to consume easily.
    • Frozen Foods: Supplement their diet with frozen foods like bloodworms, brine shrimp, and daphnia. Thaw the frozen foods before feeding to prevent digestive issues.
    • Live Foods: Provide occasional live foods such as snails, small shrimp, or insect larvae to mimic their natural diet and stimulate hunting behavior. Ensure the live foods are from a reputable source to prevent introducing parasites or diseases to the tank.
    • Vegetables: While Figure 8 Puffers are primarily carnivorous, they may nibble on blanched vegetables like zucchini or cucumber as a source of fiber and nutrients. Offer vegetables sparingly as a supplemental part of their diet.
    • Algae: Figure 8 Puffers may graze on algae growing in the tank, but it should not be their primary source of nutrition. Ensure they receive a varied diet to meet their nutritional needs.
    • Feeding Schedule: Feed Figure 8 Puffers small amounts of food 2-3 times a day, adjusting the feeding schedule based on their activity level and appetite. Avoid overfeeding to prevent obesity and water quality issues.
    • Supplemental Foods: Consider supplementing their diet with calcium-rich foods like snail shells or cuttlebone to support their dental health and prevent overgrowth of their teeth. Additionally, vitamin supplements can be added to their diet occasionally to ensure they receive essential nutrients.
    • Tank size: Provide a minimum tank size of 20 gallons for a single Figure 8 Puffer, with additional space for each additional fish to accommodate their territorial behavior.
    • Tank Length and Measurements: Choose a tank with dimensions that allow for adequate swimming space and provide plenty of hiding spots and areas for exploration.
    • Water Temperature: Maintain a water temperature in the range of 75-80°F (24-27°C) to ensure the comfort and well-being of Figure 8 Puffers.
    • pH (Acidity/Alkalinity): Aim for a pH level between 7.0 and 8.0 to maintain stable water conditions and support healthy fish.
    • KH (Carbonate Hardness): Carbonate hardness helps buffer pH fluctuations in the water. Aim for a KH level between 5-15 dKH (90-270 ppm) to maintain stable water parameters.
    • GH (General Hardness): General hardness refers to the concentration of dissolved minerals in the water, particularly calcium and magnesium. Aim for a GH level between 5-15 dGH (90-270 ppm) to ensure optimal health and growth.
    • Hardiness: Figure 8 Puffers are relatively hardy fish when kept in suitable conditions with stable water parameters. However, sudden fluctuations in water parameters can stress them and lead to health issues.
    • Nitrate (NO3) levels: Monitor nitrate levels in the aquarium and keep them below 20 ppm through regular water changes and maintenance. High nitrate levels can negatively impact fish health and water quality.
