Starry Puffer (LiveAquaria)
The Starry Puffer, also known as the Stellate Puffer, has an orange body with dark spots. It grows to be one of the largest puffers in the world. In the home aquarium, it rarely grows over 2 feet in length, but in the wild, it can reach 4 feet. 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 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 300 gallon or larger, fish-only aquarium with a good protein skimmer is suitable. It will eat invertebrates found in a reef tank. It becomes alarmed when netted, therefore, use a container to transfer it safely.

The Starry Puffer is a striking fish with vibrant orange coloring and dark spots. It’s active and interesting to watch, especially when it inflates. I have a 400-gallon tank and it’s adapted well. I use a container when handling it to avoid stressing it.

This fish is large and needs a spacious tank. I noticed it eats small invertebrates from the reef setup. It’s not for beginners due to its size and sensitivity to handling.

The Starry Puffer is visually impressive and adds a unique presence to the tank. It inflates when startled, which is both fascinating and a bit dramatic. I’ve kept it for over a year and it’s healthy and active.
