(Tetraodon biocellatus)
The Figure 8 Pufferfish (Tetraodon biocellatus) is a small, eye-catching species known for its vibrant green and black markings that resemble the number “8.” Native to Southeast Asia’s brackish waters, this puffer is a favorite among aquarists for its curious personality, intelligent behavior, and truly unique appearance. It's ideal for hobbyists ready to venture into the rewarding world of brackish or species-specific tanks.
Key Features:
-
Striking Pattern: Lime-green top with distinct black “figure 8” markings and a creamy white belly make it a standout in any setup.
-
Intelligent & Interactive: Recognizes its keeper, explores its environment, and often watches from the glass—these puffers have real personality.
-
Compact Size: Grows to about 6–8 cm (2.5–3 inches), making it ideal for smaller species-only or brackish tanks.
-
Specialized Care: Best suited for aquarists with some experience due to its dietary needs and water preferences.
Tank Requirements:
-
Minimum tank size: 75 liters (20 gallons) for a single puffer
-
Temperature: 24°C–28°C (75°F–82°F)
-
pH: 7.5–8.5
-
Brackish water recommended (low salinity around 1.005–1.008 SG) for long-term health
-
Provide plenty of hiding spots, rocks, and décor to satisfy their curious nature
Tank Mates:
-
Best kept solo or with extreme caution in a species-only tank
-
Can be aggressive or nippy, especially toward slow or long-finned tankmates
-
Never house with small, passive fish or inverts like snails and shrimp (they're a snack!)
Feeding Tips:
-
Carnivorous with a strong need for hard-shelled foods to wear down constantly growing teeth
-
Feed a varied diet of snails, bloodworms, clams, krill, and shrimp
-
Avoid flakes or pellets—live or frozen foods are best
