The porcupine fish (as Diodon antennatus) is mentioned in Charles Darwin's famous account of his trip around the world, The Voyage of the Beagle. He noted how the fish can swim quite well when inflated, though the altered buoyancy requires them to do so upside down.
The long-spine porcupine fish is an omnivore that feeds on mollusks, sea urchins, hermit crabs, snails, and crabs during its active phase at night. [5] They use their beak combined with plates on the roof of their mouths to crush their prey such as mollusks and sea urchins that would otherwise be indigestible.
Attractive and relatively small, Hawkfish make excellent additions to fish only or FOWLR aquariums. With extreme caution taken, they could be kept in reef aquariums, but because of their propensity to eat small ornamental shrimps and other mobile invertebrates (usually leaving sessile invertebrates alone) they are not considered reef safe.
The Black-blotched porcupinefish is a medium-sized fish which grows up to 65 cm (26 in), but the average size most likely to be observed is 45 cm (18 in). [1] Its body is elongated with a spherical head with big round protruding eyes and a large mouth that is rarely closed.
Tangs, which by most accounts are reef safe, may in adulthood eat some crustaceans shortly after they molt. Many larger predatory fish, for instance eels and pufferfish, will adapt very well to a reef tank and will be problem-free as long as they have sizable tank-mates and no crustaceans. Some aquarists have also had success in keeping smaller ...
The experiment included raising over 5,000 fish between the years 2001–2004, and analyzing the toxicity of muscle, skin, gonads, livers, and other organs. The team concluded that the amount of tetrodotoxin in all those parts was non-toxic, and it would allow for the safe preparation of fugu-kimo (puffer liver). [63]

The spot-fin porcupinefish is a medium-sized fish which grows up to 91 cm, but the average size mostly observed is 40 cm. [2] Its body is elongated with a spherical head with big round protruding eyes, and a large mouth which is rarely closed.
