Green-Spotted Puffer Starter Care Guide
A practical introduction to green-spotted puffer care, including health risks, water quality, tank setup, food and behaviour.

About the Green-Spotted Puffer
Green-spotted puffers are bright green, black-spotted pufferfish that become much larger and more demanding than their juvenile store size suggests. They need increasing salinity as they mature and adults are commonly kept in high-end brackish or marine conditions.
They are intelligent, active predators with strong teeth. Puffing is a stress response and should never be deliberately caused.
Health risks to know about
Important concerns include overgrown teeth, ammonia or nitrite poisoning, salinity shock, parasites, poor nutrition, aggression injuries and swallowing air if lifted from water.
Teeth blocking the mouth, a pinched belly, rapid breathing, repeated scratching, wounds or abnormal swimming needs prompt aquatic-veterinary care.
Tank, water and equipment
Use a large, mature, fully cycled aquarium with marine salt mix, a calibrated refractometer, powerful filtration, a secure lid, open swimming room and complex sight breaks.
Plan the adult salinity before purchase and raise it only through measured, gradual changes. Pre-mix and aerate replacement water before it enters the tank.
Food and feeding
Offer varied hard-shelled aquatic foods and suitable meaty foods so normal chewing helps wear continuously growing teeth.
Avoid feeder fish, overfeeding and large leftovers that can quickly damage water quality.
Behaviour, tank mates and enrichment
Active patrols, hunting and interaction with safe objects are normal. Aggression usually makes community housing unreliable.
Plan a species-focused adult tank. Smaller fish and invertebrates are likely to be bitten or eaten.
When to contact an aquatic veterinarian
Get help for gasping, collapse, severe wounds, major swelling, inability to stay upright, rapid unexplained deaths or a problem that continues after water parameters are corrected.
Test ammonia, nitrite, nitrate, pH, temperature and salinity whenever behaviour changes. Water quality is part of the medical history, so record results before contacting an aquatic veterinarian.
