Figure Eight Puffer

Name: Figure Eight Puffer
Scientific Name: Tetraodon biocellatus
Maximum Length: About 2–3 inches (as adults)
Favorite Things: Brackish to freshwater aquariums with lots of rockwork or driftwood, moderate flow, and stable water. A high-intelligence fish known for interacting with keepers and investigating their environment. Enjoys a varied diet of snails (for beak wear), frozen mussels, and quality wafers/pellets.
Best Buddies: These fish are semi-aggressive and tend to nip fins or harass slow tankmates; best kept in species-only setups or with robust fish of similar temperament. Not recommended with delicate shrimp or small tetras.
