Panda Puffer (Masked Pufferfish) – LiveAquaria
The Panda Puffer, also known as the Masked Pufferfish, has black patches around both eyes. It lacks pelvic fins, but has learned to use the pectoral fins to move about the aquarium. It has the ability, when threatened or alarmed, to inflate its body to almost twice its normal size. While “puffed up,” its spines are held straight out from the body to discourage others from trying to eat it. Parts of the flesh are poisonous if digested. Its teeth are actually a fused beak-like structure.
A 180 gallon or larger, fish-only aquarium with a good protein skimmer is suitable. It will eat invertebrates found in a reef tank. It does become alarmed when in a net and will expand its body for protection, therefore, use a container to transfer it.
The Panda Puffer needs a varied diet of meaty foods such as mysid shrimp, copepods, and small crustaceans.

The Panda Puffer is a fascinating addition to my 200-gallon reef tank. It’s active and curious, and the way it inflates when startled is quite impressive. I feed it mysid shrimp and copepods daily. It’s a bit of a challenge to handle, but once acclimated, it’s a rewarding pet.

I’ve had the Panda Puffer for six months now. It’s not the easiest fish to keep, but the unique behavior and appearance make it worth it. I make sure to transfer it using a container to avoid stress. Feeding it a varied diet keeps it healthy and active.

This fish is a true showstopper. The black eye patches and inflation behavior are mesmerizing. I’ve learned to handle it carefully, and it’s adapted well to the tank. I recommend only for experienced aquarists with large tanks.
