Common Name: Freshwater Golden Avocado Puffer
Scientific Name: Auriglobus modestus
Other Names: Golden Puffer, Avocado Puffer
The Freshwater Golden Avocado Puffer is a small, vibrant freshwater pufferfish known for its attractive golden-yellow coloration and compact size. This species is popular among aquarists for its striking appearance and engaging personality. Despite its small size, the Golden Avocado Puffer is an active and curious fish that requires specific care to thrive.
Habitat and Distribution: The Freshwater Golden Avocado Puffer is native to the freshwater rivers and streams of Southeast Asia, particularly in countries like Thailand, Cambodia, and Vietnam. These fish inhabit slow-moving waters with abundant vegetation and hiding spots, providing them with plenty of foraging opportunities and shelter. The water in their natural habitat is typically warm, soft to moderately hard, and slightly acidic to neutral.
Size and Lifespan: In both the wild and captivity, Freshwater Golden Avocado Puffers typically grow to about 2-3 inches (5-7.5 cm) in length. Their lifespan can range from 5 to 8 years, depending on the care and conditions provided in the aquarium. Ensuring a proper diet, clean water, and adequate space are crucial for their longevity and well-being.
Diet and Behavior: Freshwater Golden Avocado Puffers are carnivorous and have a varied diet that includes small invertebrates, crustaceans, and other meaty foods in the wild. In an aquarium, their diet should consist of live or frozen foods such as bloodworms, brine shrimp, snails, and other small crustaceans. Providing hard-shelled foods like snails is essential to help wear down their constantly growing teeth. These puffers are known for their active and curious behavior, often exploring their surroundings and interacting with their environment. However, they can be territorial and may nip at tank mates, making them best suited for species-only setups or with carefully chosen tank mates.
Breeding and Reproduction: Breeding Freshwater Golden Avocado Puffers in captivity is rare and challenging due to their specific environmental needs and behaviors. Little is documented about their breeding habits in the wild, and successful reproduction typically involves creating conditions that closely mimic their natural habitat. A separate breeding tank with optimal water conditions, plenty of hiding spots, and careful monitoring of aggression is necessary for any breeding attempts.
Aquarium Care and Tank Requirements: To keep Freshwater Golden Avocado Puffers, a tank of at least 20 gallons is recommended for a single fish, with larger tanks required for multiple individuals. The tank should include plenty of hiding spots created with rocks, driftwood, and dense plants to mimic their natural habitat and reduce stress. A soft, sandy substrate is ideal to protect their delicate underbellies. Efficient filtration and regular water changes are essential to maintain water quality, as these fish are sensitive to poor conditions. Gentle to moderate water flow is suitable to replicate their natural environment.
Ideal Tank Mates: Due to their territorial nature and potential for nipping, Freshwater Golden Avocado Puffers are best kept alone or in a species-only setup. If tank mates are desired, they should be carefully chosen and monitored. Suitable tank mates might include fast-moving, non-territorial fish that can avoid the puffer, but even this carries risk. Generally, it is safest to keep these puffers in a species-only setup to prevent potential conflicts and stress.
Difficulty Level: Intermediate. While they are hardy and adaptable, their specific dietary needs, potential for aggressive behavior, and requirement for clean, well-maintained water require attentive care and a well-thought-out aquarium setup.

Additional Information:
- The Freshwater Golden Avocado Puffer’s vibrant coloration and active behavior make it a captivating addition to a specialized aquarium, providing both visual interest and a unique pet-keeping experience.
- These fish have strong, ever-growing teeth that require regular wearing down, so providing hard-shelled prey like snails is essential for their dental health.
- In their natural habitats, Freshwater Golden Avocado Puffers play a role in controlling populations of small invertebrates, contributing to the ecological balance.
- Fun fact: Despite their small size, Golden Avocado Puffers can inflate their bodies by gulping water or air when threatened, making them appear larger and deterring potential predators. This defense mechanism is a fascinating behavior to observe but should not be triggered unnecessarily in captivity, as it can be stressful for the fish.
