• Temperament: Semi-aggressive, territorial; best kept alone or in carefully managed species-only groups

Diet & Nutrition

• Omnivorous: Yes — but highly carnivorous by preference. Feed live or frozen foods like bloodworms, brine shrimp, daphnia, and snails (which help wear down their ever-growing teeth). They typically do not accept dry foods like flakes or pellets.

Appearance

• Tiny, round body with large, curious eyes
• Bright greenish-yellow coloration with dark mottled or spotted patterns
• Males often have deeper coloration and wrinkles behind the eyes (used during courtship)

Distinctive Features

• One of the few truly freshwater puffers
• Rotating, independent eyes similar to chameleons
• Capable of "hovering" in the water like a hummingbird
• Sharp beak-like teeth that require regular wear through snail consumption
• Known for their engaging and intelligent behavior, often recognize their owners
