Saltwater Aquarium Groupers

Groupers are large and aggressive saltwater fish that do well in very large aquariums. Most Groupers will grow well over 12 inches in captivity and need a large tank full of swimming room and hiding places to thrive. Groupers can be kept in reef tanks, but will eat smaller fish and shrimp given the chance. For this reason you must proceed with caution if adding a Grouper to your reef tank. Groupers can be aggressive to other similar species if the aquarium is not large enough for more than one.

Miniatus Grouper
Cephalopholis miniata

Picture of Miniatus Grouper

Description: The Miniatus Grouper, also known as the Miniata Grouper, Coral or Blue-Spot Rockcod, Coral Hind, and Coral Grouper, is a common and popular fish along the coral reefs of the Indo-Pacific, and it makes a most spectacular addition to a large home aquarium. In the wild, it can attain sizes up to 18", but tank specimens rarely exceed a foot in length. Like all groupers, it will eat any fish that they can swallow whole and behave aggressively towards tank mates that intrude into its preferred hiding place. It will also eat ornamental shrimps and crabs. Although it can be shy when initially introduced to the aquarium, with time it will spend more time in the open, becoming quite bold in time. It is compatible with other aquarium fish provided they are too large to be eaten.

Tank Recommendations: Can be maintained in ‘large’ reef or fish-only aquariums with several caves and ledges. May initially be somewhat shy, but will become more social in the coming weeks. Overall, somewhat peaceful, but will protect/chase away from what it considers its territory/areas in the aquarium. Will consume smaller tankmates.

Food and diet: As to diet, these are carnivores and require a diet high in protein and amino acids (lipids/fats). Products such as marine fish and crustacean flesh, clams, and other marine meaty foods should make up the majority of their diet. Therefore a meaty diet such as enriched chopped fresh fish or shrimp flesh, and/or frozen carnivore foods should be fed. And because these are not overly active fish, their metabolism is somewhat low, so feeding once every other day should suffice nicely. May be difficult to feed in the early days in the aquarium and if so, (if small live marine fish are not available) live glass/grass shrimp and/or small crabs, e.g., fiddler crabs may be needed to sustain the fish.

Clown Grouper
Pogonoperca punctata

Picture of Clown Grouper
You Tube Video of the Clown Grouper
Description: The Clown Grouper, also known as the Spotted Soapfish, Snowflake Soapfish, or Leaflip Soapfish, is silverish-brown with white spotting over the entire body. It has black tiger stripes along its dorsal edge.. Their most distinguishing characteristics are the five black, triangular spots that are located along the dorsal side of the fish. This grouper will prey upon most smaller fish and motile invertebrates. These groupers have been known to attempt eating fish you might not think they could swallow. Clown groupers should be provided with plenty of both open swimming room and rock caves and tunnels. They have large appetites, and a meaty frozen diet is recommended.
Tank Recommendations: Can be maintained in ‘large’ reef or fish-only aquariums with several caves and ledges. May initially be somewhat shy, but will become more social in the coming weeks.

Description: A very popular grouper and saltwater aquarium fish, this is perhaps one of the easiest to care for of all available marine groupers. A fast growing fish that needs plenty of food. Large specimens are commonly used to cycle new aquariums. This grouper is rarely aggressive, definitely more passive than most groupers and will ignore its fish tankmates, unless they are small enough to swallow whole.

Tank Recommendations: Can be maintained in ‘large’ reef or fish-only aquariums with several caves and ledges. May initially be somewhat shy, but will become more social in the coming weeks.

Click to view You Tube Video Red V-Tail Grouper

Description: Red V-Tail Grouper, Cephalopholis urodelus, comes from the Indo-Pacific and from the Hawaiian Islands. It is also known as the Flag Tail Grouper and Banded Tail Sea Bass. Its red body reflects sheens of grey and green in different lighting. The "V-Tail" portion of its common name comes from the two distinct nearly-iridescent stripes on its tail fin. With the potential to grow to nearly a foot in length, the Red V-Tail Grouper should be kept only in larger aquariums. In the home aquarium, it has little interest in corals, but may likely dislodge corals as it darts after its next meal. It may eat any fish that will fit into its mouth. Crustaceans, being part of its natural diet, will likely be eaten.

Tank Recommendations: Can be maintained in ‘large’ reef or fish-only aquariums with several caves and ledges. May initially be somewhat shy, but will become more social in the coming weeks. Overall, somewhat peaceful, but will protect/chase away from what it considers its territory/areas in the aquarium. Will consume smaller tankmates.

Click to view You Tube Video Cherry Louti Grouper

Description: The Cherry Louti Grouper in the wild will reach lengths of over 24 inches therefore it requires a great deal of space to grow. We recommend an aquarium of at least 180 gallons. Its coloration begins with a cherry red at the dorsal that fades into a pale yellow underneath. Its uniquely-shaped V-swept tail is another prominent feature. Although it can be quite shy when initially introduced to the aquarium, with time it will spend more time in the open, becoming quite bold. Like all groupers, it will eat any fish that it can swallow whole and will behave aggressively towards tank mates that intrude into its preferred hiding place.

Polleni Grouper
Cepholopholis polleni

Click to view You Tube Video Polleni Grouper

Description: The Pollenei Grouper is a stunning and large grouper. Pollenei Groupers have a mostly yellow body with strong purple horizontal lines on their body. As the Pollenei Grouper matures, it starts to become darker in color. Pollenei Groupers reach a maximum adult size of around 17 inches and need to be kept in tanks that are at least 220 gallons. Pollenei Groupers are aggressive fish and shouldn't be kept with passive smaller fish. Pollenei Groupers might also take a liking to your inverts. For these reasons if you want to add a Pollenei Grouper to your reef tank, you must proceed with caution. Pollenei Groupers will thrive in larger fish only systems where they will add a huge dash of color to your tank. It is recommended that the Pollenei Grouper be kept with other large semi-aggressive to aggressive fish as well. Since the Pollenei Grouper is such a large fish, it is best to provide them with a lot of free swimming room.

Tank Recommendations: Can be maintained in ‘large’ reef or fish-only aquariums with several caves and ledges. May initially be somewhat shy, but will become more social in the coming weeks.

Blue Spotted Grouper
Cephalopholis argus

Picture of Blue Spotted Grouper
You Tube Video of the Blue Spotted Grouper
Description: The Blue Spot Grouper is a common favorite among aquarists with FOWLR (Fish Only With Live Rock) aquariums. Often willing to accept not only a captive diet, but to learn to eat from the hand of the aquarist is endearing. Blue spotted Groupers are found living near coral reefs throughout the Indo-pacific where they hunt for small fish or invertebrates to consume. This species is often referred to by a number of names within the marine aquarium hobby, including: Blue Dot Grouper, Argus Grouper, Peacock Hind or Peacock Grouper. The Blue Spot Groupers body is a mottled brown and tan color with six verticle white bands running from just behind the pectoral fins to the tailfin. The white bands can appear anywhere from very prominent to almost completely faded depending on the aquarium environment and the fishes current disposition. The fins are a dark blue color, with a lighter blue outline and the entire body is covered by bright blue dots.

Tank Recommendations: While this fish is considered easy to keep, it does require excellent water conditions in addition to a large aquarium to be properly housed. Bluespotted Groupers appreciate a lot of live rock with plenty of large caves and rock crevices for them to rest on and swim about. Since Bluespotted Groupers eat large meaty items, they create a lot of waste products, therefore it is important to have a very strong biological filter setup to handled the load this and other large predator species put on a filter system. This species should only be kept with other large semi-aggressive to aggressive fish species, as they will eat any fish they can fit in their mouth.

Food and diet: As to diet, these are carnivores and require a diet high in protein and amino acids (lipids/fats). Products such as marine fish and crustacean flesh, clams, and other marine meaty foods should make up the majority of their diet.

Blue line Grouper
Cephalopholis formosa

Picture of Blue line Grouper

Description: The Blue Line Grouper, also known as the Boenacki Grouper or Blue-lined Hind, is light red with multiple vertical blue lines. The fins are highlighted with dark blue. Blue Line Grouper or as they are also commnly known as the Boenacki Grouper, or Blue-lined Hind, or Blue Line Sea Bass are an Indo-Pacific grouper that dwells in and around coral reefs and rocky areas. This species is best suited for FO (fish only) or FOWLR (fish only with live rock) aquariums with other large aggressive or semi-aggressive fish species.

Tank Recommendations: Blue Line Groupers require large aquariums with excellent filtration to accomodate their size and feeding habits. As Blue Line Groupers eat large meals they end up producing a lot of waste products, which means they need excellent filtration (especially biological and mechanical) in order to keep the water quality high. While this species is not harmful to corals, it is best suited for fish-only aquariums as it will eat any fish that it can fit in its mouth and will eat most any type of crustacean. Blue Line Groupers live near the fringes of coral reefs in the wild, they should be provided an aquarium environment that contains both live rock formations and open swimming areas. They do best with other large predatory species (triggerfish, eels, sharks, etc.) or with adult semi-aggressive species (large angelfish, tangs, etc.).

Food and diet: As to diet, these are carnivores and require a diet high in protein and amino acids (lipids/fats). Products such as marine fish and crustacean flesh, clams, and other marine meaty foods should make up the majority of their diet. Therefore a meaty diet such as enriched chopped fresh fish or shrimp flesh, and/or frozen carnivore foods should be fed.

Description: The Marine Betta, Calloplesiops altevelis, also known as the Comet, is found in rocky ocean area up to around 45 meters. Both hardy and disease resistent. It is a predator by nature, it swims and hovers in a "head down" position, with its false "eye spot" near the tail resembling the head of a moray eel. When first introduced into the aquarium it will act shy, and will spend time in hideaway's in the aquarium rock. With time it will spend more time in the open, becoming quite bold. The Marine Betta is not a common site in a reef type of aquarium, but it is been proven safe with live corals and anemones. All groupers including the Marine Betta will eat any smaller fish and all ornamental shrimps and crabs. It is compatible with all aquarium fish provided they are too large to be eaten.

Tank Recommendations: Can be maintained in ‘large’ reef or fish-only aquariums with several caves and ledges. May initially be somewhat shy, but will become more social in the coming weeks.
