|Latin name||Cirrhitus rivulatus - Valenciennes, 1846|
|Local name||Giant hawkfish|
|Family||Cirrhitidae - Cirrhitus|
|Max length||60 cm (23,6")|
|Minimum volume||600 l (158 gal)|
|Suitable for aquarium||Suitable with care|
|Reef safe||Reef safe with caution|
|Aggressiveness||Might be aggressive towards other species|
Larger crustaceans (Shrimp, crabs...)
Small crustaceans (Krill, mysis, artemia...)
This spicies might be a threat to smaller fishes.
This species poses a threat towards shrimps and crabs etc., which are relatively small.
These fish flourish better without other members of the same species in the aquarium.
This species needs good hiding places, for example, between live rocks.
This species is nocturnal and therefore the most active when the light is dimmed or turned off.
Hawkfish stay still and wait for food most of the time, they are therefore suitable for smaller aquaria.
One must be aware that Hawkfishes can be very aggressive.
Very aggressive genera
The very aggressive species will sometimes attack many different types of fish, even the ones that are larger than themselves.
Semi aggressive genera
The semi aggressive species are most threatening towards fish whose behaviour mimcks their own, and fish which are introduced after they have settled in.
Less aggressive genera
The less aggressive species are rarely threatening towards fish that which do not resemble them.
Larger Hawkfishes might eat small fish, shrimps etc. in the aquarium. Species of the Cyprinocirrhites and Neocirrhites genera are least likely to eat shrimps etc.
Hawkfish do not place many demands on their surroundings or water quality, as they are fairly hardy.
It is possible to keep several Hawkfish together, but sometimes they will suddenly begin to fight after some time in the aquarium.
This may be due to them changing gender so one can end up with two males.
|Distribution||Eastern Central Pacific: Gulf of California to northern Colombia and the Galapagos Islands.|

"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.
