Combine their aggression with their carnivorous diet and you have a fish that is difficult to keep with others. The Blue Line Grouper can be seen spending a lot of its time behind rocks and corals.
This keeps them safe from other predators while also giving them an easy ambush spot to catch other fish. Even large tangs may become skittish when the Blue Line Grouper is sitting around the corner.
The Blue Line Grouper is a thick, strong fish who can easily kick around decorations or unstable live rocks. Behavior & Aggression The Blue Line Grouper is over a foot long and quite thick.
If you do plan on keeping the Blue Line Grouper with multiple large, aggressive fish you will need a larger tank of 200+ gallons. While swimming in place they will look for food, keep an eye on their tank mates as well as watch any nearby humans.
When designing your thank you will want the width to be no less than two feet, giving the fish ample space to turn around. These fish, while often calm towards other species, will not stand for another of their kind in a small environment.
This, while interesting to see, makes a huge mess and can splash water several feet from the tank. This means foods with the bones and organs still inside, not prepared for human consumption.
The Blue Line Grouper hunts by sight, meaning he cannot eat what he cannot see. If your fish rarely notices food in their tank try feeding with a skewer.
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. Jordan, 1923 Tribe Epinephrine Sleeker, 1874 Aethaloperca Fowler, 1904 Affected Bloch & Schneider, 1801 Anyperodon Gunther, 1859 Cephalopods Bloch & Schneider, 1801 Chromites Swanson, 1839 Dermatologist Gill, 1861 Epimetheus Bloch, 1793 Gonioplectrus Gill, 1862 Graciela Randall, 1964 Hyporthodus Gill, 1861 Mycteroperca Gill, 1862 Paranoia Guillemot, 1868 Plectropomus Pen, 1817 Scotia J.L.B.
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.
In November 2013, a 310 kg (680 lb) grouper had been caught and sold to a hotel in Dong yuan, China. ^ a b c d e Richard van der Loan; William N. Scholar & Ronald Cricket (2014).

Wiki source has the text of the 1905 New International Encyclopedia article Grouper “. In the wild, it can attain sizes up to 18", but tank specimens rarely exceed a foot in length.
In the wild this reef predator commonly attacks schools of reef-dwelling fish. In the aquarium, freeze-dried krill soaked in Season, feeder goldfish, or squid are acceptable.
Fernando Rodriguez Carolina, PR The Miniature Grouper is very pretty fish and also a very aggressive one. Zachary HTA Spokane, WA Excellent fish, very beautiful.
He does not bother tangs, triggers, emperor angel or remaining small fish (damsels, antics and hawkish), but he has a burn-on for the Spanish and Cuban Dogfish. 6 months in, and he has grown to a healthy 9 inches and is the most beautiful fish in the tank.
Groupers are a large family of saltwater fish characterized by their stout bodies and over-sized mouths. Although a hardy, colorful and highly fascinating species of fish, groupers should only be kept by dedicated aquariums with ample space to raise them.
Although most aquarium varieties only grow to around 12 inches in length, they still require extremely large accommodations. Groupers are a large family of saltwater fish characterized by their stout bodies and over-sized mouths.
Most aquarium kept species of grouper are incredibly colorful and have complex patterns and markings on their bodies. They come in shades of red, yellow, orange, blue, green, purple, brown, white and black.
They also prefer aquariums with large open swimming spaces as well as plenty of hiding places. However, they are able to exist quite peacefully with larger species of fish and other groupers provided that they are housed in sufficiently large aquariums.
This is also important if you’re introducing a new fish to an aquarium with a grouper in it as it can respond aggressively towards new tank mates. Groupers are carnivores and should be fed on a varied diet of live and frozen foods like shrimp, bait fish, scallops and squid.
Swimming Region(s): Mid-Range Suitable Tank Mates: Other Non-Aggressive Species of Similar Size; Other Surgeon fish, Tangs, Unicorn fish Difficulty Of Care : Daily The size of these fish, coupled with the patterns and colors of some grouper species make then wonderful show specimens for a large marine tank.
Groupers exhibit an extreme range of sizes, from mere inches to many feet long and weighing hundreds of founds. In many species, individuals all mature as females, and only the most dominant fish in a group will become a reproductive male.
Groupers can make great aquarium inhabitants, provided their husbandry needs such as diet, water quality and tank space are met. However, groupers do not pose a direct threat to corals, so they may be kept in a reef tank with only large fish as companions.
While smaller species such as the Pollen Grouper (Cephalopods pollen) are suited to tanks as small as BLANK GALLONS, larger species such as the Panther Grouper (Chromileptis actively) may be better suited to a larger tank. As a result, analysts have developed many diagnostic groupers to group ICD10 codes into meaningful categories for analysis.
Several are available within Insight; the MARA risk scores, the Chronic Condition Hierarchical Groups (CCS), several available episodic groupers, and our Evidence Based Measures quality metrics. Some of the most common use cases for groupers are chronic condition cost and prevalence analysis, chronic condition management, estimating patient and population risk, disease pathways and cost of treatment, performance management and quality measures, and care management case finding.
These questions can easily be answered by Insight’s Chronic Conditions Hierarchical Groups (CCS). CCS’ embedded hierarchy will filter out other complex conditions, and give you the ability to measure a clinically similar group of members.
For estimating overall population risk, risk-scoring for a physician panel, or any sub-population of patients, MARA is the best grouper to use. Disease pathways and cost of treatment helps to measure the efficiency of care for a specific condition.
Episodic Groupers are the best option when answering questions such as: What is a standard pathway for cancer treatment? CCS is used here to zero in on patients with specific, chronic conditions, such as diabetes or CAD.
Adding MARA brings patients to the surface who are most likely to be impactable in better clinical outcomes, lower costs or both. This is a very powerful way to prioritize your scarce and valuable care manager time.
In conclusion, the suite of groupers available in the Insight Ecosystem are each designed to serve a specific primary purpose and complement each other for patient or population level analysis. For each project or initiative you should choose the grouper within your toolkit that is the best match for the desired application.

Groupers are ambush predators and will spend much of their time hiding and watching for easy prey. Caution should be considered when adding this animal to a community tank as it will eat any fish or crustacean that may fit in its mouth.
These foods include krill, raw table shrimp, squid, clam and mussel. It is also a good idea to occasionally supplement with some type of herbivore diet.
