The clown triggerfish (Balistoides conspicillum), also known as the bigspotted triggerfish, is a demersal marine fish belonging to the family Balistidae, or commonly called triggerfish.
The clown triggerfish is a fish which grows up to 50 cm (19.7 inches). [2] Its body has a stocky appearance, oval shape and compressed laterally. The head is large and represents approximately one third of the body length. The mouth is small, terminal and has strong teeth. [2]
The first dorsal fin is composed of three spines, one of which is longer and stronger. It is erectile and hidden in a dorsal furrow. This set of dorsal spines composed a trigger system which is a characteristic from the family Balistidae. The second dorsal fin is similar in shape and size to the anal fin which is symmetrically opposed to it. The pelvic fin is reduced to a ventral protrusion. [2]
The background coloration is black. Half of inferior part of the body is marked with big white spots which are more or less round. The area around the first dorsal fin is crossed by yellowish sinuosities which draw like a network reminding the leopard's patterns. There is a yellowish ring around the mouth, which is surrounded by another fin white ring. A white stripe ride the snout just under the eyes level. The second dorsal fin and the anal fin are white and underlined with a yellow line at their base. The caudal peduncle has a yellowish blotch on its top part and has three horizontal sets of spiny scales. The caudal fin is yellowish in its center and has black margin. Juveniles have a black background coloration spangled with small white spots, the extremity of the snout and the base of the first dorsal fin is yellowish. [3]
The clown triggerfish is widely distributed throughout the tropical and subtropical waters of the Indian Ocean and in the western Pacific Ocean. [4] A single record was reported in the Mediterranean Sea in spanish waters in 2012, a likely aquarium release. [5] It is most commonly found along external reef slopes with clear water until 75 m depth. [6] Juveniles are usually staying below 20 m sheltered close to caves or overhangs.
Balistoides conspicillum has a varied diet based on different benthic organisms like molluscs, echinoderms and crustaceans. [7]
This triggerfish has a diurnal activity, is solitary and defends a territory. It can be very aggressive with other fish and congeners. The first long dorsal spine when is erected, it is used to impress an opponent or to avoid a predator to pull it out of its refuge.
Because of its attractive coloration, this fish is one of the most highly prized aquarium fish. [8] Like many other triggerfish, it can require a large aquarium and be aggressive towards other fish. It should not be kept with small fish. It will also prey on invertebrates in the aquarium. [9] [10] This fish can become tame enough to be hand-fed; however, one should beware of the fish's sharp teeth. [10]
Triggerfish are about 40 species of often brightly colored fish of the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the oceanic triggerfish, are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered.
The filefish (Monacanthidae) are a diverse family of tropical to subtropical tetraodontiform marine fish, which are also known as foolfish, leatherjackets or shingles. They live in the Atlantic, Pacific and Indian Oceans. Filefish are closely related to the triggerfish, pufferfish and trunkfish.

The emperor angelfish is a species of marine angelfish. It is a reef-associated fish, native to the Indian and Pacific Oceans, from the Red Sea to Hawaii and the Austral Islands.

It is found in the western Indian Ocean and, more recently, in the eastern Mediterranean Sea.
The blackbelly triggerfish is a ray-finned fish in the family Balistidae found in the Indo-Pacific. It occasionally makes its way into the aquarium trade. It is sometimes known as the blackpatch triggerfish.
Xanthichthys ringens, the Sargassum triggerfish, is a species of triggerfish from the Western Atlantic, ranging from North Carolina (USA) to Brazil.
The Lei Triggerfish is also known as the bursa triggerfish, scythe triggerfish or boomerang triggerfish, is a triggerfish from the Indo-Pacific. Its name is derived from the two markings behind its eyes that wrap around the fish similar to a Hawaiian Lei. The color of these markings changes depending on the fish's mood, in which case the colors may alter from yellow, dark brown, and black. It is a species of reef fish found in reef ecosystems in the Indo-Pacific, including Japan, Australia, and Hawaii. It occasionally makes its way into the aquarium trade.
