Looks how to spot one
Round-bodied puffer with prickly skin that can inflate
A rounded body with a blunt, dog-like face and small prickles over the skin. The colour varies a lot, from grey or light brown to bluish or bright yellow, with dark patches around the eyes and mouth and scattered dark spots.21
Personality what they are like
Calm, gentle and known for interacting with the people who care for it. Wild adults are territorial and often solitary.32
Daily activity how busy a day looks
A relaxed swimmer that needs plenty of open space in a large tank.3
Grooming and care the hands-on bits
Rated moderate care. Not reef-safe. Strong filtration and protein skimming help, and regular partial water changes keep water clean.3
Home where they are happiest
A tank of at least 125 US gallons (about 475 L). Saltwater at about 24 to 26 °C (76 to 78 °F), pH 8.1 to 8.4, specific gravity 1.024 to 1.026. Wild fish live on coastal and outer reef crests and slopes rich in invertebrates, down to about 60 m.31
Food basics what goes in the bowl
Feed hard-shelled foods such as clams and mussels plus frozen meaty marine foods. Juveniles eat daily, adults a few times a week. Wild fish eat coral tips, crustaceans, molluscs, sponges, tunicates and algae.31
Company who they like around
Usually solitary or in pairs in the wild. Keep one per aquarium.12
The story where it all began
Marcus Elieser Bloch and Johann Gottlob Schneider described the species in 1801. It is a familiar fish in public aquariums and in the marine aquarium hobby.21

Owner questions the things everyone asks
How often should I feed my Dogface Puffer?
Juveniles should be fed daily, while adults do well a few times a week. Furry Diary's starting plan suggests small amounts once or twice a day, but always check the food label and ask your vet for the exact amount.31 Furry Diary plan
What does a Dogface Puffer eat, and what should it never eat?
It thrives on hard-shelled foods like clams and mussels, plus frozen meaty marine foods. Avoid feeding anything that isn't part of a marine puffer diet; consult your vet for a safe list.31
How much space does a Dogface Puffer need?
A minimum of 125 US gallons (about 475 litres) is needed, with plenty of open swimming space. This allows your gentle puffer to swim comfortably.31
What temperature, light or water does a Dogface Puffer need?
Keep saltwater at 24 to 26°C (76 to 78°F), pH 8.1 to 8.4, and specific gravity 1.024 to 1.026. Furry Diary's plan suggests daily temperature checks and weekly salinity checks. Lighting needs are not specified, but standard marine lighting is fine.31 Furry Diary plan
How often should I clean a Dogface Puffer's home?
Perform a partial water change of about 10 to 20% every two weeks, and clean the glass weekly. Regular water testing and strong filtration are also important.3 Furry Diary plan
Can a Dogface Puffer live with others?
It is best kept alone, as it is usually solitary and can be territorial. A single puffer per tank is recommended.21
How long does a Dogface Puffer live?
With proper care, a Dogface Puffer can live between 10 and 15 years.3
Can I handle a Dogface Puffer?
It is best not to handle your Dogface Puffer, as it has prickly skin and can inflate when stressed. Enjoy watching its interactive personality from outside the tank.21
