FAQ
Is this pufferfish safe to keep with other fish in a community tank?
This species is semi-aggressive and not recommended for community tanks with small or slow-moving fish. It may pose a threat to smaller fish or invertebrates. A tank with larger, robust fish and no sensitive species is advised.
What is the expected growth rate of this pufferfish?
The Yellow Belly Dogface Pufferfish typically grows to a mature size of 13 inches. Growth rate can vary based on diet, water quality, and tank conditions, but it generally reaches full size within 2 to 3 years.
Can this pufferfish survive in a tank smaller than 75 gallons?
No, a minimum tank size of 75 gallons is required for proper health and behavior. Smaller tanks may lead to stress, stunted growth, and increased aggression.

Bought this for my 80-gallon tank. It’s active and curious, though it does nip at smaller fish. I’ve added larger fish and it’s now coexisting well. Water parameters are stable and the fish looks healthy.

The fish arrived healthy and has been active since setup. I keep it with larger tetras and a few corydoras. It’s not aggressive toward them, but I avoid keeping it with shrimp or small fry.

It’s a bit aggressive at first, especially when feeding. After a week, it settled into a routine. I now have a 75-gallon tank with a few larger fish. Would recommend for experienced aquarists.
