Bioluminescence, just like glow worms and fireflies.
These fish produce certain chemicals in their bodies that react, emitting energy in the form of light. Depending on the chemicals involved, the colour of the emitted light varies. It is called bioluminescence because the reactions are biochemical in nature; most use enzymes, for example.
Chemiluminescence is the correct process name, wikipedia it.
