Sexing[edit | edit source]

No visible differences between male and female fish. In the wild, a single male are usually found with a group of females.


Tank compatibility[edit | edit source]

Peaceful towards other tank mates. HOWEVER, not only can this fish be easily startled and injure itself trying to hide. It is also highly toxic. Its skin contains ostracitoxin. If it gets stressed out or sick, it will release a toxin into the water that will kill everything around it. It is perfectly capable of wiping out your entire tank. When introducing this fish, do not let ANY bag water into the tank, and during water changes if the fish needs to be taken out, put it in a container alone.


Diet[edit | edit source]

Will take most meaty foods or vegetables.


Feeding regime[edit | edit source]

Twice a day.


Environment specifics[edit | edit source]

Needs a large tank with plenty of hiding places. Not particularly reef safe as it will eat inverts. Excellent water quality is necessary to keep this fish happy and healthy. They don't appreciate strong currents.


Behaviour[edit | edit source]

Slow swimming very curious fish. Will examine anything new in the tank very closely.


Identification[edit | edit source]

Distinctive yellow cube shape with two long "horns" extending from it's forehead. As this fish matures, these "horns" will get shorter.
