Small crustaceans (Krill, mysis, artemia...)
Larger crustaceans (Shrimp, crabs...)
This species grows very quickly if fed well.
Hard to give this species the correct nutrition and is therefore hard to keep alive.
This species can be a threat towards small fish, shrimps, small bivalves, worms, snails and the like.
This species searches through the sand for food, which can make the water cloudy and shakes up detritus.
In an aquarium their natural food source in the sand is quickly exhausted.
This species needs a very large aquarium when fully grown.
Exactly how big the aquarium should be is hard to say, but the size of this species is such, that it cannot normally be kept in a home aquarium.
This species must be fed with an appropriately varied diet.
This species eats a great deal and demands an aquarium that can tolerate such a heavy load.
There is a greater chance of success with this species if one can supply a living feed to allow it to adapt to the tank.
This fish requires feeding several times a day, especially when newly added.
When the fish can find its natural food in the aquarium it requires less frequent feeding.
This species needs good hiding places, for example, between live rocks.
This species revels in swimming and requires an aquarium with ample space.
This species is very shy and docile, so one should be careful when keeping it with more aggressive fish.
Fish within in the Grunt family do not often appear in private aquaria, but can be kept in a very large tank under proper conditions. They are predatory fish and mostly live off benthic crustaceans, worms and fish.
There can be a big difference in appearance when the fish is young and fully grown.
This family can divided into two groups: Plectorhinchinae (Sweetlips) and Haemulinae (Grunts).
Aquarists normally find Sweetlips to be the best looking, but they can be difficult to feed and it can be problematic giving them food containing enough nutrition. Grunts are more hardy and quicker to start feeding in aquaria.
It can be a good idea to have live food, Mysis or small live freshwater shrimp, in case these fish don't begin to feed.
One should not acquire these fish with the intention of selling them on when they get bigger. This is, not only because they grow quickly if fed correctly, but also because they are difficult to sell on to domestic buyers.
Sweetlips include the genera of Diagramma and Plectorhinchus.
Grunts include the genera of Anisotremus and Haemulon.

"Minimum volume" indicates the size of the tank needed to house this species under optimal conditions.
This is based on a medium size animal, which you want to keep for several years.
It might be possible to keep smaller specimens for a limited period in a smaller tank. A larger tank might be needed for fully-grown specimens.
"Hardiness" indicates how resistant this species is to disease and how well i tolerates bad conditions in general.
Some species doesn't handle transportation very well, but that doesn't mean that the species isn't hardy under the right conditions.
In this case, a "normal" aquarium is a reef aquarium with mixed corals or a fish only aquarium with an approximately salinity of 1.026 (sg) and a temperature close to 26°C.
Species requiring more than a 4000-liter tank are considered not suitable for home aquarium.
Special aquariums may cover tanks with low salinity, sub-tropical temperature, deep sand bed, sea grass etc.
Always reef safe: No sources indicate that this species will harm corals or other invertebrates.
Often reef safe: Only a few aquarists has reported problems keeping this species with corals and other invertebrates.
Reef safe with caution: This species may be a threat to some types of invertebrates.
Reef safe with luck: Most specimens will harm corals and/or other invertebrates, but you might be lucky.
Not reef safe: This species is a threat to most corals and/or other invertebrates.
