The dorsal profile of the head is flat to slightly convex between the eyes. It has a rounded, finely serrated properly which has a fleshy lower edge.

The maxilla extends beyond the rear of the eye. The membranes of the dorsal fin has distinct indentations between its spines.

The dorsal fin has 9 spines and 14-15 soft rays while the anal fin has 3 spines and 8-9 soft rays. The color of the body is orange- red to reddish brown with many small bright blue spots which cover the head, body and the dorsal, anal and caudal fins.

The color of the juveniles is orange to yellow with fewer widely separated faint blue spots. They attain a maximum total length of 50 centimeters (20 in).

Cephalopods minima is found in clear water where there are coastal and offshore coral reefs, it prefers exposed rather than protected areas. Like other groupers this species is predatory, over 80% of its diet consists of small fish, predominantly sea oldies (Pseudanthias squamipinnis) which are ambushed by the coral hind in a sudden rush up from the substrate.

They form harems consisting of a single male and up to 12 females. The male defends the harem's territory which is around 475 square meters (5,110 sq ft) in area, each female has a smaller territory which she defends against other females.

Coral hinds are protogynous hermaphrodite, and they change sex from female to male. The male patrols the territory and visits each female, swimming parallel to each other when they meet.

Cephalopods minima is an important species in commercial fisheries at the local level and is caught using hook and line, fish traps and spears. It is a colorful species and is popular in public Aquarian and forms a minor part of the aquarium trade.

They can reach 17” (44 cm) and groupers are known to live from 9 to 37 in the wild, possibly longer in captivity with proper care. The Cephalopods genus, commonly referred to as “Hinds,” contain smaller species of groupers which are more appropriate for home aquariums.

The second challenge would be filtration, since groupers are big eaters and produce copious amounts of waste, requiring a good quality oversized skimmer and two canister filters like Exam or Fluvial. The canister filters should be cleaned twice as often as the directions suggest in order to keep them working effectively.

A slender fish and even eels that are the same length as your Coral Hind will be consumed. As the Peacock Grouper ingests a long and narrow tank mate, the prey fish/eel coils up in its belly.

At times, they will try to eat a fish they can’t quite get down their throat, then the aquarium will have to lend a hand to extract the unfortunate tank mate. Other tank mates are safer if they are deep bodied and over 1/3 the size of the adult Coral Hind.

If attempting to keep with cleaner shrimp from the Lyman or Steno pus genus, add them first. Coral Hinds need to be the last fish added to an aggressive community tank.

Well arranged live rock work will help them to adjust and will help provide the biological filtration which needs to be aided by a strong skimmer and two efficient canister filters. They prefer to hide under ledges and in caves, but will sit at the bottom of the tank near their hideout as they become more comfortable.

They are found in southern Japan and then south to Lord Howe Island. In the wild, Coral Hinds feed mostly on Lyre tail Antics (Pseudanthias squamipinnis), but will also eat Tories (Canthigaster margarita ta), Cardinal fish (Aragon), Blue Green Chromes (Chromes irides), sweepers, tangs and Stenosis SP.

Coral Hinds in the Red Sea hunt with Gray Morays (Sidereal rise) and octopuses who are foraging for food. Similar to others in this genus, juveniles probably prefer hiding deep within dense coral thickets.

As adults, Coral Hinds are in harems that consist of one male and 2 to 12 females. These harems will cover 475 square miles which are divided into secondary territories and defended by a female.

Coral Hinds have small eyes that are mounted near the top of the head, which is typical for editorial fish. An adult will take on a mottled appearance that is a mix of bright red and orange (juvenile coloring) when hunting or interacting with other hinds.

They can reach 16” (41 cm) and groupers are known to live from 9 to 37 in the wild, possibly longer in captivity with proper care. Provide them with a tank that is at least 100 gallons and several hiding places within the live rock.

The tank should have a heavy-duty skimmer and two external canister filters that are cleaned often, due to the large amount of waste this fish produces. Feeding groupers fresh water fish will cause health issues if continued for too long.

Do not house them with other Coral Hinds, although they will be fine with other groupers as long as the tank is large enough. If an individual will not eat, offer feeder fish or ghost shrimp.

Once they are eating, quickly switch over to prepared foods such as freeze-dried or frozen krill, mys id shrimp and pellets for carnivores. Also offer a varied diet of raw crustacean and fish flesh which can be obtained from the grocery store.

Large Tanks 100 gallons and over, once water is aged and stable can be changed 20% to 30% every 6 weeks depending on bio load. Large Tanks 100 gallons and over, once water is aged and stable can be changed 10% bi-weekly to 20% monthly, depending on bio load.

In a 100 gallon tank (378 liters), arrange live rock, forming several places like overhangs and caves for the Coral Hind to hide, especially if the fish is a juvenile. They may be induced to spawn indoors if they are conditioned with more feedings, then the temperature is raised 2F, and there is a longer daylight period.

Coral Hinds, although found in harems in the wild, are best kept singly in a captive environment. In very large 500 to 1000 gallon systems, outside saltwater ponds or public aquariums, a few females can be kept with a male.

Also, arrange the live rock to provide barriers where their vision of each other is blocked from their normal hangout. Keep Coral Hinds with fish of similar size if they are not as deep bodied, such as tangs and trigger fish who should be at least 13” long and fish who are deep bodied like butterfly fish and angelfish who are at least 7” long.

The only time the Coral Hind becomes a threat, is if it is full-grown and these other fish are not, and they fit in their mouth! Figure out what kind of water quality you can maintain and only buy corals that are not picky.

This starts at dusk, with a peak in spawning happening at the new or full moon. Males will spawn with each of the four or five females in the same night, with both releasing their gametes into the water column.

Typically, groupers are extremely hardy, but do tend to come in with multiple parasites. A culture was done on wild-caught groupers and there were 11 to 16 different species of parasites found on their bodies, including nematodes and cryptocaryon.

The most easily cured parasite is Crypt (salt water ICH), but they are all treatable if caught in a timely manner. ONEMA is often contracted when the aquarium doesn’t lower their salinity to the proper level of 1.009.

The ONEMA parasite thrives in mid-level brackish water salinity, which is a specific gravity of around 1.013 to 1.020. Quick Cure and other 37% Formalin products will work perfectly well in both salinity ranges, but the lower 1.009 will help with the oxygen level.

Anything you add to your tank from another system that has not been properly cleaned or quarantined, including live rock, corals, equipment and fish can introduce diseases. 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 MiniatusGrouper 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.

Its typical coloration is a red -orange with lighter broad bands running horizontally starting just behind the gill plate. The brilliant blue spots covering its body are a very notable feature.

With the potential to grow to over a foot in length, the MiniatusGrouper should be kept only in larger aquariums. It welcomes a diet of smaller live fish upon which it can prey with a sudden, unexpected burst of speed and frozen krill or other meaty prepared foods.

In the wild, MiniatusGrouper can attain sizes up to 18", but tank specimens rarely exceed a foot in length. A Beautiful and fairly easy to keep fish, just give MiniatusGrouper enough space and carefully consider tank mates.

In the wild, this reef predator commonly attacks schools of reef-dwelling fish. Since groupers are generally larger fish, it is recommended waste removal efforts be increased within the aquarium system.

Feeding and Diet: It is recommended to keep one MiniatusGrouper per aquarium, as they are prone to fight with one another. It will eat any fish it can swallow whole (including cleaner wrasses) and will behave aggressively towards tank mates that intrude on its preferred hiding places.

General Size Specifications: In the aquarium Miniature Group typically does not exceed 7-10 inches. The MiniatusGrouper tends to be easily excited and caution should be exercised in quick movements around the tank for it is a reported jumper, therefore, the aquarium should be covered as good as possible at all times.

Habitat: The MiniatusGrouper range from the Red Sea to the mid-Pacific living in coral reefs looking for smaller fish upon which to dine. MiniatusGrouper, better known as Rock Cod or Coral Grouper is a type of saltwater fish that belongs to the Serranidae family (which includes the bass antics).

Even when mixed together among its own species, the male fish can show high level of aggression which will readily defend intrusion into its territory. The fish is a popular choice especially for those people who prefer having solitary setup rather than a community environment comprising different types of species which often complicates things due to compatibility issues.

The groupers are the type of fish which rarely move around but when they do, you will be surprised upon seeing their quick reflexes which are trademarks of its predatory instinct. Before we proceed further, it is good that we should first understand the general behavior and other specific care details. The Recommended Aquarium Setup First, the fish loves to hide among reefs’ openings and for that matter, you should ensure that arrangement of the corals and live rocks will permit your pets to do so.

Although not necessarily a must, this requirement actually mimics the natural setup in the wild and it helps newly acquired fish to acclimatize to the artificial home aquarium environment. Thus, it would be a good idea to provide some kind of natural buffering effect in the tank or if you have the extra cash to spend, you can actually consider installing a pH adjuster with a probe or sensor to take the current reading.

They love market fish, which you can either slice it or chopped into smaller pieces or you can just feed to them in chucks depending on the size of the mouth opening, which of course larger adults will need less attention. However, be forewarned that any introduction of live foods even shrimps have to undergo proper quarantine procedure or else you will risk introducing unnecessary disease into the aquarium.

Strategy on Disease Prevention As mentioned earlier, coral groupers are hardy fish which will rarely show any sign of complications unless they are severely mistreated and forced to live in poor water quality. They are relatively disease resistant and if for any reason that you notice signs of fungus infestation especially presence of white spots and fluffy growth on their gills and body, you can opt to use any conventional chemical treatment to counter the infection.

Watch out also for parasites such as isopod, bristle worms or other marine worms which can inadvertently introduced to the tank when putting in new batch of corals and if you notice this pest around, make an all out effort to remove them. Breeding and Reproduction Successful artificial propagation to produce the fish in bulk has been reported but somehow in smaller aquarium environment, it can prove to be more difficult.

Constant supply of brine shrimps will ensure that the small fish achieve a healthy growth rate and usually under proper care, you can see them attain reasonable size of at least an inch in less than a month. The MiniatusGrouper should be kept in a tank with plenty of live rock structure that will provide them multiple hiding places.

With such a large appetite, be sure to equip a powerful protein skimmer in addition to strong biological and mechanical filtration.
