Care
The Bluestriped Butterflyfish is endemic to Hawaiian waters, where it is most commonly observed at rocky and coral reefs to depths of 28m (92ft). Juvenile fish frequent protected, shallow reef flats during the summer months, with adults swimming in deeper areas, either as solitary fish or in small aggregations of 3-15 individuals. This is an omnivorous species, feeding mostly on benthic invertebrates, especially polychaete worms, plus stony coral polyps and various algae. This somewhat shy species is regarded as moderately hardy, but is best suited to experienced aquarists. A good-sized, mature system is requisite, along with ample live rock for the fish to browse upon/hide amongst and a large open swimming space along the front of the aquarium. Medium sized specimens tend to acclimatise better to aquarium life, adapting much more quickly to various prepared foods, so try to choose a healthy, alert specimen around 7.5cm (3") in length. Smaller sized fish may be very reluctant to feed, and larger specimens can sometimes be rather finicky, requiring faultless water conditions. An aquarium that has some areas of lush filamentous algae growth will also aid your new fish in settling into its new surroundings; however, as with other butterflyfish species, these fish demand excellent water quality - thoroughly filtered and well oxygenated, with areas of brisk current. Some aquarists have successfully kept the Bluestriped Butterflyfish alongside some of the more noxious soft corals, but this is something of a risk, and they should be observed carefully. Stony corals and many other sessile invertebrates will be constantly nipped at, so unfortunately must be avoided. Keep only one Bluestriped Butterflyfish per tank (unless a mated pair is acquired) and not with any other butterflyfish as they will squabble over territories. Whilst they can be rather shy when first introduced, providing them with ample retreats amongst the live rock should ensure they quickly gain confidence and venture out into the open. Tankmates should be of similar size and temperament; it is imperative that boisterous companions are avoided if this fish is to settle in and feed. The colouration and markings of the Bluestriped Butterflyfish are fairly distinctive, with well-settled individuals displaying a vibrant yellow background colour and thin blue stripes running diagonally over the body from the snout. Unusually, there is no 'mask' over the eye, a trait common in most (but not all) butterflyfish. There is a small black spot on the top of the head area, and a larger black blotch just in front of the caudal peduncle, the latter of which is thought to aid in confusing predators. May also be seen on sale as Bluelined Butterflyfish or Hawaiian Bluestriped Butterflyfish.
