Life of Baloonfish

Life of Sea | Baloonfish (Diodon holocanthus) | It is known as Long-spine porcupine fish. The Baloonfish is in circumtropical distribution. It is found in the tropical regions of the great seas and oceans. It can be found in the Atlantic Ocean, in the western Indian Ocean and the Pacific. They are reef fish with a depth range of 200-100 m. They are found on the muddy sea floor, or in lagoons and seaward reefs and around the world.

The body of the Baloonfish is covered with long, sharp spines that extend when the fish is inflated by taking in water. All members of the family Diodontidae able to account for inflation, and can also change color when threatened. Baloonfish are nocturnal predators, usually hiding in crevices in the reef during the day. The teeth are fused forming a strong, beak-like mouth for the consumption of snails, sea urchins, and hermit crabs. These fish are relatively poor swimmers. The young people are consumed by pelagic predators such as tuna and dolphins. Adults fall prey to sharks.

Baloonfish are known for their large eyes, spines and their ability to swell like a balloon when attacked. This rather droll reached between 20-35 cm to a maximum of 50 cm. They have a total of 13-15 dorsal and anal soft rays. Young people have spots on their belly (bottom) sides, adults have dark spots and blotches on their back (upper) side. They have 14 to 16 spines between their dorsal fins and snouts. A big brown bar is found above and below each eye, and a broad transverse brown bar on their occipital region (back of the head).

Baloonfish have a pelagic life stage. Spawning occurs after males slowly push women to the surface. The eggs are buoyant, hatch after about four days. The larvae are well developed with a functional mouth, eyes, and a swim bladder. They are mostly yellow with scattered red spots, and covered with a thin shell until about 10 days old, after which the shell is lost and the spines begin to form. Approximately three weeks after hatching, the fins and fin rays are present and the teeth are formed. As young people develop their olive to brown with dark spots on the ventral side that serve as camouflage for young people floating in Sargassum weed. The spotting is maintained until the boy moved to shore and adults.

Baloonfish is used in Chinese medicine, and is captured on the surface with a hand net. It is toxic if not properly prepared. In the cavity, Baloonfish is aggressive against members of his own species and other species. It should be fed meaty meals (fish, squid, shrimp, mussels or krill). If no algae in the aquarium, green stuff should be added. Ideally the fish should be fed no less than three times a day. The Baloonfish is mostly at night and the day to hide until they are fully acclimatized. It's a funny pet and fish can also owned by the bite - a painful experience. You should not provoke inflation, because it can air, which is very difficult to be removed and taken deadly. Netting is also not recommended as it can blow into the net, making removal very difficult.
