The PantherGrouper can get to be about 27 inches (70 cm) when fully grown, and they eat like it's going out of style. To adequately keep them you should be thinking about a 300 plus gallon aquarium (1135 liters).

The juvenile groupers around 3 or 4 inches are collected on the reef and sold to stores, but they can quickly outgrow most tanks. The larger groupers are a food fish and sold in Asian markets.

They will eat most meaty type fish foods such as silver sides, crustaceans, squid, etc. So lots of cover (live rock) will be needed to help make them feel secure.

As they grow they will become bolder but for the most part will leave other similarly sized fish alone, including other Panther Groupers. Breeding : Fish base reports a spawning event in 1979 but the eggs died.

Will eat crustaceans and smaller fish but should leave the corals alone. The PantherGrouper is the most widely available grouper in the aquarium industry and for good reason, they are hardy and gorgeous.

They thrive best in tanks with a good filtration system to cycle waste as well as plenty of live rock hiding places. However, the PantherGrouper Fish or Polka Dot Grouper is a legitimate predator and will eat anything that will fit into its mouth.

They thrive best in tanks of at least 50 gallons with a good filtration system to cycle waste as well as plenty of live rock hiding places. Juveniles display fewer, larger black spots, against a bright white background.

These black spots become smaller and more plentiful as the fish matures and the white becomes more grayish. This unusual fish is also unique amongst the groupers in having an elongate, slender head that rises sharply at the nape of the neck, giving the species the distinctive ‘humpback’ appearance.

The long dorsal fin begins at the top of this ‘hump’ and extends almost the entire length of the body. These large and graceful fins together with its body shape and coloration serves the purpose of camouflage.

Panther Groupers are relatively slow swimmers; they prefer to cruise about the reef looking for possible meals and patrolling their territory. The PantherGrouper is very popular and periodically available; if you have patience it shouldn’t be hard to find this species for sale sooner or later at your local fish store.

The PantherGrouper lives a long time (with proper care) and is a very hardy fish. Many consider it one of the easiest marine fish to care for and adult specimens of this species are often used to help cycle new aquariums.

I am sure many eager fish keepers have been lured into buying one due to their beauty and the fact that they are mostly sold when they are small, around 5-10 cm in size. As these fish can consume large amounts of meaty foods you filtration will need to be good.

A good quality large protein skimmer along with frequent water changes will do the trick. In the wild, this species swims along the reefs hunting for prey and you should keep this in mind when decorating your aquarium.

They prefer an aquarium with suitably sized hiding places in caves and overhangs as well a lot of open space to swim in. Tank mates for the PantherGrouper include some Tangs, Wrasses, Angelfish, Trigger fish, Eels, Sharks, and Lionfish.

The PantherGrouper is a predator of smaller fish and some ornamental invertebrates, so caution should be exercised there. Never keep it with small fish like damsels or clowns as they will end up as food sooner or later.

Goldfish or other freshwater feeder fish are not a good food choice as they lack the nutrients that the PantherGrouper needs to maintain a healthy immune system. While this is not a guarantee for success, it will greatly enhance the odds of the two groupers finding a balance of territory and co-existing peacefully.

Scientific classification Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Performed Family: Serranidae Subfamily: Epinephrine Tribe: Epinephrine Genus: Completes Swanson, 1839Species: Binomial name Completes actively Synonyms Genus Species Serra nus actively Valentines, 1828 Epimetheus actively (Valentines, 1828) The humpback grouper is a medium-sized fish which grows up to 70 cm (28 in).

Its particular body shape makes this grouper quite impossible to mix up with other fishes. This stocky and strange visual effect is accented by its concave profile and its elongated snout which gives it a humpbacked appearance.

The young have a white background with round black spots and are continuously swimming head down. It is widely distributed throughout the tropical waters of the central Indolent Pacific region.

> The humpback grouper lives in clear waters from lagoons and seaward reefs with a preference for dead or silty areas. The diet of this grouper is based on small fishes and crustaceans.

Like the members of its family, the humpback grouper is reversal, solitary (except during mating periods), defends a territory, and is an ambush predator. Its feeding activity is maximal at sunrise and/or at sunset.

This species is a protogynous hermaphrodite ; in other words, all individuals are born female, with the ability to transform to males as they grow older. The humpback grouper has been give Data Deficient status by the IUCN.

It is a highly valued food fish, especially in Southeast Asia and in this region it is over exploited. It is bred in aquaculture but there is no evidence that captive breeding has reduced the fishing pressure on wild populations.

Australia has put strong conservation measures in place for this species(no take species in Queensland and possession limits in other states, e.g. Western Australia) but it is lacking protection elsewhere. ^ a b Scholar, W. N.; R. Cricket & R. van der Loan (eds.).

That's sucks but from what I know about grouper they will eat anything that can fit in its mouth watch your tank My tanks are 35 and 45 gallons My wife put the maroon clownfish in with the panther grouper the other day because she said it didn't look happy with the other cellars clowns.

My tanks are 35 and 45 gallons My wife put the maroon clownfish in with the panther grouper the other day because she said it didn't look happy with the other cellars clowns. Yes, that is impressive, it is ashamed the number of panthers being sold to the unexpected.

Please do not assume all people who are in the hobby are ignorant or that common sense is absent-minded. But nice touch lion king with the discreet verbiage used to imply that I was just another newly saltwater fish keeper.

I read it as a just a comment about the enormous size these fish grow to and the voracious appetites they have. Many LFS are not upfront with customers about this, and people loose fish because of it...and this is a prime example with the clownfish.

Not to mention they place the grouper in a tank that is soon to be way too small, when they may not have plans or means to upgrade. While you are not a newbie, apparently your wife did not understand what the grouper was capable of, or she may have reconsidered which tank the clown fish’s “happy place” was located.

Most LFS(likely almost all) will not take them back, and I have seen countless these fish euthanized when the hobbyist seems as if they have no other choice. In all decency this fish should be left in the ocean as very few have the system to adequately take care of them.
