What is a Dogface Pufferfish?
The dogface pufferfish, or Arothron nigropunctatus, is a large saltwater fish. It has a round body and a face that looks like a dog’s. This makes it very popular among fish keepers. It has black spots on its body, which is why it is also called the blackspotted puffer.
These fish live in warm ocean waters. They are strong and hardy but need special care when kept in an aquarium.
Tank Size and Setup
Dogface puffers can grow quite large. They can reach up to 18 inches (45 cm) or more. This means they need a big tank. A tank of at least 100 gallons is best. Bigger tanks are even better for these active fish.
Here is a simple table to show tank size needs:
| Fish Size | Recommended Tank Size |
|---|---|
| Up to 12 inches | 100 gallons |
| 12 to 18 inches | 125 gallons or more |
The tank should have good water flow and hiding spots. Use rocks, caves, and plants that can live in saltwater. The dogface puffer likes to explore and hide sometimes.
Water Conditions
Water quality is very important for dogface puffers. These fish do not like dirty or unstable water. Keep the water clean and stable for their health.
- Temperature: 74 to 80°F (23 to 27°C)
- Salinity: 1.020 to 1.025 specific gravity
- pH Level: 8.1 to 8.4
- Ammonia/Nitrite: 0 ppm (zero)
- Nitrate: Keep below 20 ppm
Regular water testing is needed. Change about 10-20% of the water every week. This helps keep the water clean and safe.
Feeding Your Dogface Pufferfish
Dogface puffers have strong teeth that keep growing. They need hard foods to wear down their teeth. Without this, their teeth can grow too long and cause problems.
Here are good foods for dogface puffers:
- Hard-shelled snails
- Crabs
- Clams
- Frozen shrimp and squid
- Other meaty frozen foods
Live food is very important for tooth care. It helps the puffer chew and grind its teeth naturally.
Feed your puffer 1-2 times a day. Smaller meals are better than one big meal. This keeps the fish healthy and active.

Do not keep dogface puffers with aggressive or very small fish. Watch how the fish interact and separate if needed.
