Tetraodon nigroviridis

Common name: Green Pufferfish

Origin: Found in brackish and freshwater environments across Southeast Asia, including parts of Thailand, Cambodia, and Vietnam, typically in rivers, lakes, and coastal areas.

Optimal living conditions:

• Temperature: 24 - 28°C
• pH: 7.0 - 8.0 (slightly alkaline, brackish)
• Aquarium size: 100 liters+ (for a single fish or small group)

Adult fish size: 12 - 15 cm

Diet: Carnivorous. Tetraodon nigroviridis enjoys a diet of live and frozen foods, including snails, crustaceans, and small fish. Their teeth grow continuously, so it is essential to provide foods like snails to help naturally wear them down. A varied diet with a good balance of protein sources is recommended.

Tankmates: Tetraodon nigroviridis can be quite territorial and aggressive, especially towards smaller fish. It is not recommended to house them with peaceful or smaller species. They are best kept alone or with other large, robust fish that can handle their sometimes aggressive nature. Puffers are typically solitary fish, and keeping multiple in a small space may lead to territorial disputes.

Note: This species is known for its vibrant green coloration and its ability to inflate itself as a defense mechanism when threatened. Like other pufferfish, Tetraodon nigroviridis requires a specialized diet to manage its dental health, as its teeth grow throughout its life. It also thrives in a brackish water setup, and it is essential to replicate its natural environment with a suitable salinity level in the aquarium. Tetraodon nigroviridis is a challenging species for novice aquarium keepers and should only be considered by experienced aquarists who are equipped to meet its dietary and environmental needs.

Note: This chart provides only the basics. Conduct thorough research before bringing this species into your tank to ensure you can meet all of its needs for a long and healthy life.
