The longhorn cowfish is a member of the boxfish family, instantly recognizable by the two horn-like projections above its eyes and its boxy, armored body. It moves through the tank with a slow, almost comical swimming style that has made it a favorite among marine aquarists. However, when heavily stressed, it can release a skin toxin called pahutoxin, which may harm or kill tankmates, so care must be taken when choosing companions. It grows to a maximum of about 46 cm, giving it a notable presence in the aquarium as it matures. Considered a fish for experienced keepers, it calls for careful attention to water quality and tankmate selection. Its distinctive look and unusual behavior make it a marine fish that rewards those willing to learn its needs.

关于角箱鲀
A boxfish relative known for its horn-like head spikes and boxy body. Grows up to 46 cm and can release toxin under stress — best suited to experienced keepers.
迎接角箱鲀前需要了解的7件事
1Choose Tankmates Carefully
Under heavy stress, this fish can release a skin toxin called pahutoxin that may harm or kill tankmates. Choose calm, non-aggressive tankmates and avoid situations that could cause excessive stress.
2Grows Up to 46 cm
This species can reach up to about 46 cm in length as an adult. Plan ahead for a tank with enough swimming space to accommodate its eventual size.
3Best for Experienced Keepers
Due to its sensitivity to water quality changes and the risk of toxin release, this species is considered suitable for experienced aquarists. It's best to gain marine fishkeeping experience before bringing one home.
4Distinctive Swimming Style
Because of its rigid, boxy body, it doesn't swim smoothly like most fish but instead hovers with a distinctive, almost bobbing motion. This charming movement is part of what makes it so popular.
5Notable Horn-Like Projections
The two horn-like projections on its head are its most defining trait and the source of its common name. These horns can become more prominent as the fish matures.
6Maintain Stable Water Quality
This fish is thought to be sensitive to sudden changes in water parameters. Regular water testing and careful, gradual water changes are essential to keeping it healthy.
7Prepare the Tank Before Arrival
Before bringing one home, set up your tank with its eventual size and tankmates in mind. A layout that minimizes stress is an important part of the preparation process.
