• Coloration: Their coloration can vary, but they typically have a greenish-brown base with a striking figure-eight-shaped pattern on their backs. Some individuals may also have spots or stripes.

Caring for Your Figure 8 Puffer

Providing proper care for your Figure 8 Puffer is essential for their well-being and longevity. Here are some key aspects to consider:

Habitat Requirements

• Tank Size: A minimum tank size of 20 gallons is recommended for a single Figure 8 Puffer. However, a larger tank is always better, as it provides more swimming space and reduces the risk of aggression.
• Water Parameters: They prefer brackish water conditions, with a specific gravity of around 1.005 to 1.010. The pH should be between 7.5 and 8.5, and the temperature should be maintained between 78°F and 82°F.
• Filtration and Water Changes: A powerful filtration system is crucial to maintain water quality. Regular water changes of around 10-15% every week are also necessary to remove waste and replenish essential minerals.
• Substrate: A soft, sandy substrate is ideal for Figure 8 Puffers, as they like to burrow and sift through the sand.
• Decorations: Provide plenty of hiding places, such as rocks, caves, and driftwood, to help reduce stress and provide a sense of security.

Diet and Nutrition

• Food Type: Figure 8 Puffers are carnivorous and require a varied diet consisting of live or frozen foods, such as brine shrimp, mysis shrimp, and chopped seafood. Occasional treats of freeze-dried or pellet foods can also be offered.
• Feeding Schedule: Feed your Figure 8 Puffer small amounts several times a day, rather than one large meal. This helps prevent overeating and digestive issues.
• Variety: Offering a variety of foods is essential to ensure your puffer is getting all the nutrients it needs.

Tank Mates

Due to their aggressive nature, Figure 8 Puffers are best kept in a species-only tank. However, if you want to introduce tank mates, choose peaceful and non-aggressive species that are significantly smaller in size to avoid any potential conflicts.

Common Health Issues

Figure 8 Puffers are generally hardy fish, but they can be susceptible to certain health issues, including:

• Ich: A common parasitic infection that causes white spots on the body and fins.
• Fin Rot: A bacterial infection that causes the fins to become ragged and deteriorate.

Regular monitoring of your puffer’s health and prompt treatment of any signs of illness are essential for their well-being.
