This species likes eating anemones.
This species poses a threat towards shrimps and crabs etc., which are relatively small.
This species can be fastidious and in an aquarium it can be very difficult to get them to eat sufficiently.
This species demands a high water quality.
Amongst other things it means, that water must be properly oxygenated.
It is recommended that this species be kept by experienced aquarists as it requires specialized food for its continual survival.
This species often becomes malnourished in captivity, it is therefore important to enrich their food with omega-3 and vitamins.
This species is easily susceptible to Marine Ich (Cryptocaryon irritants), when stressed by other fish, bad water quality, or when relocated.
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 species thrives best in an aquarium with overhangs and caves.
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.
This species can be very shy when first introduced into a new aquarium.
More aggressive fish can be introduced after this species has acclimatized.
When young this fish has a very impressive appearance, but develops a bland colour and loses its special shape when fully grown.
Batfishes are not well suited to coral aquaria, as they pose a threat to shrimps, anemones, corals and other invertebrates.
They grow fairly quickly, a small fish can grow to be 25 cm in height within a couple of months.
These fish will begin eating quickly, with the exception of Platax pinnatus, but will sometimes hide for a few days after being transported.
Be careful when catching the fish as their fins are easily damaged.
Batfishes should be fed with both algae based foods and different types of frozen food or seafood.
Many Spadefish cannot adjust to captivity and become much too big, but several species of the Batfish (Platax genus) can be kept in a large aquarium.
|Distribution||Western Pacific: Ryukyu Islands to Australia. Occurrence of this species in the Indian Ocean is doubtful.|

"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.
