The Fourspot Butterflyfish is not a good aquarium fish because it is shy and is reluctant to eat. It has a distinctive appearance characterized by the two white spots on the upper sides. It inhabits Oceania, Hawaiian Islands, and various other Pacific Islands. It is not particularly common in most of these locations except certain parts of the Hawaiian Islands. It is frequently seen in pairs and is picky in its choice of habitat. Rarely seen below 10 meters, it is usually found in much shallower waters. It prefers areas that are exposed to moderate or slight surge action. It does not make a good aquarium fish because it is rather shy and is reluctant to feed.
Nicely shot short video of a Golden Butterflyfish swimming amongst rocks and tankmates in its aquarium. The video has quite a few clear and closeup shots of this very pretty fish.
Nice underwater video showing a large group of Klein's butterflyfish enjoying what's left of a sea urchin, likely initially killed by triggerfish. Butterflyfish aren't above scavenging food and sea urchins are normally protected by their long spines, so a full triggerfish provides the best opportunity for the butterflyfish to dig in!
