Larger crustaceans (Shrimp, crabs...)
This spicies might be a threat to smaller fishes.
This species poses a threat towards shrimps and crabs etc., which are relatively small.
This species has a vulnerable skin, take extra care when catching or transporting, so the skin doesn´t get damaged.
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 ought to be kept in a group of at least three.
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 revels in swimming and requires an aquarium with ample space.
This species can be bred in captivity, one can therefore consider asking your local fish store for a captive bred specimen.
These fish are known for their extremely shiny and reflective skin.
Jacks/Pompanos are a large fish between 10-40 inch (25-100 cm) long, but some will grow up to 6.5 foot (2 meters).
They are predatory fish, which chase prey in open water and/or look for food on the bottom; crustaceans for example.
Some of the species are suitable for aquaria, but do require a lot of space.

"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.
