Orangespine unicornfish, like most unicornfish, tend to look a little grumpy. If they actually get grumpy, they have sharp orange spines at the base of the tail fin that they can use to express their displeasure. This doesn’t mean they’re a dangerous fish, just one not to provoke, which is a good attitude to have to any creature.

He is handsome enough to command respect even without the spines!

Their color can get very intense at certain times, but at any time they’re very striking.
