Aquarium Care

Dog Face Puffers require a spacious marine aquarium with open swimming areas, robust filtration, and stable water quality.

They are intelligent and interactive fish and often become very responsive to their keeper. However, their size and feeding habits create a significant biological load, so strong mechanical and biological filtration is important.

Avoid housing them with very small, timid, or delicate fish.

Feeding

Dog Face Puffers require a varied carnivorous diet that also helps naturally wear down their continuously growing teeth.

Offer foods such as:

• Clams and mussels

• Shrimp

• Crab

• Squid

• Marine-based frozen foods

• Hard-shelled foods whenever appropriate

A varied diet is important for long-term health.

Reef Compatibility

Dog Face Puffers are not considered reef-safe.

They may prey on or damage:

• Shrimp

• Crabs

• Snails

• Clams

• Other mobile invertebrates

They may also disturb corals while investigating or feeding.

They are generally better suited for fish-only or carefully planned FOWLR systems.
