This video helps to demonstrate the enormity of the Peacock Hinds, as you watch a Emperor Angelfish swim by in the background! The Peacock Hind grows to 17" and comes in various colors from greenish tan, to tan, brown and even burgundy. They all have a wide, bright blue margin on all of their fins. They are covered from nose to tailfin in bright blue spots that are edged in black, except the area of the chest in front of the pectoral fins, which is spotless.
This is an excellent example of how tiny juvenile Peacock Hinds, or Blue Spot Groupers can be! This little guy will eventually grow to 17" and will require a tank that is at least 180 gallons, better yet, 250 gallons. Any fish that can fit in it's mouth will be lunch, and a fish or eel that is as long as they are will also be eaten. Add as the last member of an aggressive community reef or fish only tank and provide places for them to hide. Form larger hideouts as they grow.
This is a great video of a young Coral Hind. While juveniles, they can eat up to 30% of their body weight. They like to stay close to the bottom of the tank, near their hideout. These fish grow to 16," although sometimes smaller in captivity. Only keep one per tank since they are very territorial.
This video shows two adult Coral hinds in the wild, swimming near their favorite food, the Lyretail Anthias! This male and female show the size difference, since males are larger. They can have a darker red at the back part of the body with blue accents on the back fins. These fish grow to 16" or 41 cm and are best kept singly in a 100 to 180 gallon tank. Groupers will sometimes elicit the help of octopus or Gray Moray eels to flush out a morsel hiding within the rocks or corals of the reef.
Often purchased as an adorable 2" baby, the Panther Grouper can grow 2" per month, so putting them in a 180 gallon tank is best. They swim around nose down with their big pectoral fins constantly wiggling and moving, which is one of their endearing qualities. They learn who their owner is and will perform for food! This little guy will grow to 27" in the wild, but closer to 20" in captivity and will only become a threat to any fish or crustacean that can fit into their mouth! Add them as the last member of the tank as juveniles.
Video of an adult Panther Grouper wild catch and release near Australia
The gentlemen in the video refers to the Panther Grouper as a Barramundi Cod, and acknowledges they are a protected fish and will be letting it go. The great thing about this video is that it gives the aquarist a real VISUAL of how big these fish will get. The size of the mouth is also an indication of proper tank mates! Housing them in a 250 gallon tank is widely suggested, though older literature says 180 gallons. These groupers seem to swim more than others, which would explain the need for a large tank. They are smart fish and get to know their owners!
This juvenile Whitespotted Grouper has the same lightning flash hunting reaction as the adults! Looking at the pattern we can determine that this is a juvenile fish since adults have white irregular rows of lines and large white blotches. This grouper will grow to 11.8" (30 cm) and will require a 75 to 90 gallon tank that does not have any tank mates that can fit into it's mouth! Groupers come to know their owners and are great long term pets!
This is an excellent video of an adult Whitespotted Grouper with it's adult coloring. You can see the white splotching on the body, white lines, and dark margins on the back of the dorsal, anal and tailfin. To get an idea of the full size of this fish, you can see adult Blue-Headed Wrasses nearby who are dwarfed in comparison to this 12" grouper. Most websites recommend a 150 gallon tank. This grouper is very aggressive and will defend it's hideout quite adamantly!
Video showing various stages of Marine Betta baby growth!
This video is from the company that has tank bred Marine Bettas! The fry at 16 days develop a big white spot on the sides of their bodies. This white spot is gone by 7 months old. These very peaceful fish only grow to about 7" and are compatible with most fish except the very small Green Clown Goby sized fish, aggressive or large fast moving fish that will keep them from coming out. A male and female will do well in a 75 gallon, but 2 males need a 6' tank!
If you enjoy a large aquarium with fewer but larger fish, often with distinctive personalities, Groupers may be just the fish for you! They are mostly solitary fish, prefering their own company, and they are predators!
Groupers are generally quite large fish when mature, but many of the juvenile forms are favorite aquarium specimens. Most groupers are hardy though there are a few that are more difficult to keep. Visit each fish for its particular needs.
They are a predatory fish and should therefore be feed meaty foods, such as live brine shrimp, squid, clams, and an occasional live goldfish. Feeding of freshwater feeders, such as goldfish, exclusively should be avoided since freshwater species lack certain nutrients required by the saltwater varieties.
