Brown Whitespotted Puffer
The Brown Whitespotted Puffer (Arothron meleagris), also known as the Guinea Fowl Puffer, Speckled Puffer, Speckled Balloon Fish, Golden Puffer, and Fugu, is commonly black or brown with numerous small white spots (Brown Whitespotted Puffer), but a bright yellow variety (golden puffer) is occasionally seen, and a mixture of the two morphologies with bright yellow spots and black patches also occurs.
Pufferfish have the ability to inflate by swallowing air or water. This is a protective defense puffers have that prevents them from being eaten by other fish. When it inflates itself, a predator finds it difficult to swallow or to get its mouth around the pufferfish. When inflated, this Puffer's body has a soft prickly texture, which is harmless to the touch. It is from the Indo-Pacific, and Eastern Pacific Oceans. It is occasionally collected for the aquarium trade.
The Brown Whitespotted Puffer can grow to 14" in length. It eats a wide variety of marine life, but it feeds mainly on tips of branching corals and to a lesser extent on sponges, mollusks, bryozoans, tunicates, algae, crabs, shrimps, and detritus. In captivity, it may not be quick to adjust to tank fed fares, because of its coral diet preference. However, once adjusted it may accept freshly chopped or frozen foods, such as shrimp, crab, squid and fish, and possibly herbivore diets. Of course, it is not suitable for reef tanks because it will eat the invertebrates.

Green Whitespotted Puffer
The Green Whitespotted Puffer (Arothron hispidus) will adjust well to aquarium life and eat in captivity. It has a slow going, friendly, and personable demeanor, but of course, the downside to this fish is the toxin it can exude. It is suggested for a fish-only community aquarium with fish that have the same or similar traits.
The Green Whitespotted Puffer is an omnivore, eating a wide variety of marine life, such as fleshy, calcareous, or coralline algae, mollusks, tunicates, sponges, corals, zoanthids, crabs, shrimps, tube worms, and echinoderms, as well as detritus.

This amusing fish makes a great pet. The Spiny Porcupinefish (Diodon holocanthus) will quickly learn to take hand-fed foods. As cute as it is, unfortunately, it is not considered to be reef safe as it has an appetite for snails, crustaceans and small fish. It can grow up to 20 inches in length.
