Larger crustaceans (Shrimp, crabs...)
Small crustaceans (Krill, mysis, artemia...)
This species poses a threat towards shrimps and crabs etc., which are relatively small.
Boxfish(Ostraciidae) have a unique square shape and a particular way of swimming.
They have a rather special personality, which one quickly comes to love.
Boxfish live typically off a mixture of algae, coral polyps, zooplankton, and in some cases crustaceans.
They are not normally reef safe and when small will require gentle water circulation.
Boxfish can secrete a poison when stressed or if they die, which can in the worst case, kill the contents of a whole aquarium.
Never use the water the fish was transported in.

"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.
