Bristlenose catfish have hidden cheek spines in the sides of their heads which they can flex to expose or hide them at will. They are used in threat & display behaviour, much like a betta flaring its gills.

Some bristlenose catfish even carry a mild venom on these spines.

Our Starlight ancistrus has cheek spines half an inch long!

Here's the extended cheek spines from a hopliancistrus.
The spines on other species may vary in size, quantity & colour.

Mine's just goofy, he does that all the time. He also does that when he is not in a breeding mood and one of the female approaches to him.

Cories never bother him though - he completely ignores them...
