Green Spotted Puffer
Also known as: Dichotomyctere nigroviridis
The Green Spotted Puffer (Dichotomyctere nigroviridis) is a distinctive brackish water pufferfish known for its vibrant greenish-yellow body covered in dark spots. The Green Spotted Puffer originates from Southeast Asia, including Thailand, Malaysia, Indonesia, and the Philippines, inhabiting brackish estuaries, mangrove swamps, and coastal rivers with fluctuating salinity., reaches 15 cm in captivity, typically lives 10, and is kept at 24C (75F). Individual fish vary, so treat this as a general guide rather than a guarantee.

About the Green Spotted Puffer
The Green Spotted Puffer (Dichotomyctere nigroviridis) is a distinctive brackish water pufferfish known for its vibrant greenish-yellow body covered in dark spots. It possesses the ability to inflate its body when threatened and has a beak-like dental structure adapted for crushing hard prey. This species is highly intelligent and interactive, often recognizing its keeper and exhibiting curious behaviors. While visually appealing, it demands specific brackish conditions and careful tankmate selection due to its territorial nature.
Lifespan and health
With proper brackish water maintenance and a diet rich in hard-shelled prey, Green Spotted Puffers commonly live 8 to 12 years in captivity, with some individuals reaching up to 15 years under optimal conditions; longevity is heavily dependent on preventing dental overgrowth and maintaining stable salinity. Common health issues include ich (white spot disease), fungal infections from poor water quality, and intestinal parasites; overgrown teeth requiring veterinary trimming is a frequent problem if dietary needs are not met, and prolonged freshwater exposure causes osmotic stress, lethargy, and eventual organ failure.
Overview
The Green Spotted Puffer (Dichotomyctere nigroviridis) is a distinctive brackish water pufferfish known for its vibrant greenish-yellow body covered in dark spots. It possesses the ability to inflate its body when threatened and has a beak-like dental structure adapted for crushing hard prey. This species is highly intelligent and interactive, often recognizing its keeper and exhibiting curious behaviors. While visually appealing, it demands specific brackish conditions and careful tankmate selection due to its territorial nature.
Care and tank setup
Tank setup should include a sandy substrate to mimic natural estuarine environments, along with driftwood, rocks, and hardy plants like Java fern or Anubias that tolerate brackish conditions; provide ample hiding spots and open swimming space. Maintain specific gravity between 1.005 and 1.010 using marine salt mix, as freshwater long-term leads to health decline and reduced lifespan; perform 25% water changes weekly and monitor ammonia, nitrite, and nitrate levels closely. Feed hard-shelled foods 2-3 times per week to prevent overgrown teeth, supplementing with protein-rich frozen or live foods on other days; avoid overfeeding as puffers are prone to obesity.
