Larger crustaceans (Shrimp, crabs...)
Small crustaceans (Krill, mysis, artemia...)
This species eats all kinds of fish, shrimps, crabs etc. which are of suitable size.
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 revels in swimming and requires an aquarium with ample space.
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.
|Distribution||Indo-Pacific. Eastern Pacific: southwestern coast of Baja California Sur, Mexico and Gulf of California to Ecuador (Ref. 9283).|

"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.
