Pinecone Fish (Monocentrus japonicus).  Also called the Pineapple Fish and Knight-fish.  Covered with spines, and has a brilliant yellow body. It has what appears to be a glowing smile due to the bioluminescent bacteria which inhabit the light organs found on the sides of the mouth. These symbiotic bacteria are responsible for its glow which is usually green, but occasionally red in older Pinecone Fish.  http://www.liveaquaria.com/product/prod_display.cfm?c=15+46+368&pcatid=368

Black-backed Butterflyfish (Chaetodon melannotus).   This fish grows up to 18 cm (c.7 in) long, and may live for up to 20 years. When observed at night or when frightened, this species changes color; the dorsal portion of the body turns black except for two white patches.  They are generally found between 4 and 20 m deep, usually solitary, in pairs during the breeding season. Juveniles are more commonly found inshore, in pairs or traveling in small groups.  It feeds primarily on the polyps of soft and hard corals. http://en.wikipedia.org/wiki/Blackback_butterflyfish
