Puffers

Puffers are scaleless fish that can tolerate some variation in their environment. They sometimes have spines or burrs on their skin, but are most remarkable for their ability to double or triple in size by taking in air or water rapidly. Not recommended for reef aquariums.

Diet

A well-balanced puffer diet consists of:

• Chopped squid, clams, shrimp and krill.
• Carnivorous frozen food.
• Vary diet to ensure proper nutritional balance.

Feeding

Things to remember when feeding your puffer:

• Feed 1 to 2 times a day, no more than fish will eat in 1 to 2 minutes.
• Thaw frozen food before feeding.

Housing

• Keep in an appropriately sized aquarium; provide rock and décor for hiding places and plenty of room for movement.
• Avoid unnecessarily scaring or teasing your puffer to get it to puff up as it is extremely stressful on the puffer.
• Stable water quality and parameters are critical to the health of aquatic life. If you are unsure of your water quality, Petco provides free water testing.

Normal Behavior

• Have fused teeth in beak-like jaws.
• Inflate when they feel threatened; can be aggressive.
• They may eat smaller fish and invertebrates.
• Inhabit the middle levels of the aquarium.

Habitat Maintenance

• Daily: check filter, water temperature, specific gravity and other equipment.
• Weekly: check water quality at least once a week.
• Monthly: change 10 to 25% of the total volume of water every 2 to 4 weeks, or as needed.
• Introduce new inhabitants to the aquarium gradually.

Compatibility

• Check Petco's Marine Compatibility Care Sheet for more information regarding your specific species.
