Known for growing over three feet in length and weighing more than 200 pounds, this fish is hardly built for sprints along the ocean floor. Thankfully, such monsters are not common in the aquarium, though Groupers will grow quickly and even the smaller varieties require space.

Groupers are predominantly floor-dwelling and prefer to dig themselves into the substrate or to hide themselves in a reef and wait for prey to pass by. They have exceptionally strong gill muscles that they can use to brace themselves into a hiding place when they feel threatened.

The Alexandria Grouper is highly territorial and not recommended for community tanks as it is known for picking fights with significantly larger fish and winning. The second is a black bodied fish with yellow spots covered in white dots.

With bodies ranging in color from brown to orange, the Blue-Spotted Grouper is covered in small, turquoise spots, like freckles. In addition, the pectoral, dorsal, anal fins and tail are a deep blue.

They are highly predatory, so keeping them in aquariums with smaller fish would not be a wise idea. Because of their large size, Groupers have a somewhat ravenous appetite and require feeding often in order to keep them from going after other fish in the tank.

Grouper Malabar grouper, Epimetheus malarious Scientific classification Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Performed Family: Serranidae Subfamily: EpinephelinaeBleeker, 1874 Tribes and genera Not all errands are called 'groupers'; the family also includes the sea basses. The common name grouper is usually given to fish in one of two large genera : Epimetheus and Mycteroperca.

In addition, the species classified in the small genera Hyperion, Completes, Dermatologist, Graciela, Scotia, and Trio are also called 'groupers'. However, some hamlets (genus Affected), the hinds (genus Cephalopods), the lyre tails (genus Various) and some other small genera (Gonioplectrus, Nippon, Paranoia) are also in this subfamily, and occasional species in other serrated genera have common names involving the word grouper “.

Nonetheless, the word grouper on its own is usually taken as meaning the subfamily Epinephrine. Groupers are Telecasts, typically having a stout body and a large mouth.

They can be quite large, and lengths over a meter and the largest is the Atlantic Goliath grouper (Epimetheus Tamara) which has been weighed at 399 kilograms (880 pounds) and a length of 2.43 m (7 ft 11 1 2 in), though in such a large group, species vary considerably. They do not have many teeth on the edges of their jaws, but they have heavy crushing tooth plates inside the pharynx.

They habitually eat fish, octopuses, and crustaceans. Reports of fatal attacks on humans by the largest species, such as the giant grouper (Epimetheus lanceolatus) are unconfirmed.

They also use their mouths to dig into sand to form their shelters under big rocks, jetting it out through their gills. The word grouper is from the Portuguese name, group, which has been speculated to come from an indigenous South American language.

In New Zealand, “groper” refers to a type of wreck fish, Poly prion oxygenate, which goes by the Mori name haiku. In the Middle East, the fish is known as hammer ', and is widely eaten, especially in the Persian Gulf region.

The species in the tribes Grammistini and Diploprionini secrete a mucus like toxin in their skin called Rammstein and when they are confined in a restricted space and subjected to stress the mucus produces a foam which is toxic to nearby fish, these fishes are often called soap fishes.

Smith, 1964 Trio Randall, Johnson & Lowe, 1989 Various Swanson, 1839 The largest males often control harems containing three to 15 females.

Groupers often pair spawn, which enables large males to competitively exclude smaller males from reproducing. As such, if a small female grouper were to change sex before it could control a harem as a male, its fitness would decrease.

If no male is available, the largest female that can increase fitness by changing sex will do so. Gonochorism, or a reproductive strategy with two distinct sexes, has evolved independently in groupers at least five times.

The evolution of gonochorism is linked to group spawning high amounts of habitat cover. Both group spawning and habitat cover increase the likelihood of a smaller male to reproduce in the presence of large males.

Fitness of male groupers in environments where competitive exclusion of smaller males is not possible is correlated with sperm production and thus testicle size. Gonochoristic groupers have larger testes than protogynous groupers (10% of body mass compared to 1% of body mass), indicating the evolution of gonochorism increased male grouper fitness in environments where large males were unable to competitively exclude small males from reproducing.

Many groupers are important food fish, and some of them are now farmed. Unlike most other fish species which are chilled or frozen, groupers are usually sold live in markets.

Groupers are commonly reported as a source of Ciguatera fish poisoning. DNA barcoding of grouper species might help in controlling Ciguatera fish poisoning since fish are easily identified, even from meal remnants, with molecular tools.

In September 2010, a Costa Rican newspaper reported a 2.3 m (7 ft 7 in) grouper in Cieneguita, Limón. The weight of the fish was 250 kg (550 lb) and it was lured using one kilogram of bait.

Wiki source has the text of the 1905 New International Encyclopedia article Grouper “. You might be wondering whether there are freshwater grouper species which actually can live and stay inside fresh water environment or not.

The claim that freshwater grouper species is exist, and they can breed this fish inside fresh water environment is not true. Even though the Bumblebee grouper can adapt inside the fresh water environment, this will only happen for several years.

Then afterwards the grouper fish need to be moved into the marine water since it is their original habitat where they should life and grow properly. Thus, you should not understand this wrongly since there is no grouper species that is fresh water type of fish.

However, most of the time, they will stay in the tidal pool or the seagrass bed as it will give them the most protection. Then for food they will eat various microorganisms inside the water for example plankton, micro algae and also some crustacean.

The reason why there is no freshwater grouper species type is because when the juvenile grow bigger into adult, then they will go and move to deeper area of the sea as their natural habitat. In this area, they will feed on various reef fishes such as wrasse, snapper, dam selfish, and parrot fish.

They would also feed on different types of sea creature for example, crustaceans, lobster, crab, or octopus. That is why; you will find grouper fish stays in the coral reef which can be found in the subtropical as well as tropical region.

That is why; they would not suddenly take miles of distance to go to the fresh water area just to find food. Another unique behavior is actually showed by several grouper fish species which like to follow ell when it forages on the reef.

Furthermore, they also develop a unique behavior, so they can avoid that predator better by changing the color of their body. Of course, the grouper fish would not hide for all of their live, as they will need to reproduce which will be done on winter at the full moon period.
