BOESEMANI RAINBOWFISH – 石美人

A large shoal of Boeseman’s Rainbowfish makes for an outstanding display in a large planted aquarium. With their unusual half-and-half natural colouring of blue and yellow/orange, they really are a sight to behold when observed moving through plant cover. Boeseman’s Rainbowfish are best maintained in groups of 6 or more of their own kind, and the more you can keep together, the merrier. The tank itself should be at least 4ft long with heavy planting along the back and sides with an open swimming area in the centre. Their natural habitat comprises areas of very dense vegetation, and although they will adapt to most conditions, slightly alkaline water is preferable. Clean well-filtered water should be provided at all times, and tight fitting coverslides must be used as these fish are accomplished jumpers. As with many other Rainbowfish species, the juveniles can look comparatively drab to the absolutely stunning adult fish, and so are all too often overlooked in the shops. However, once settled into the security of the planted aquarium, these young specimens will soon begin to colour up, revealing their true adult beauty. Boeseman’s Rainbowfish are a peaceful species and will not bother smaller tankmates, as their mouth/throat is too narrow to be able to swallow them. Ensure that potential tankmates are happy at the slightly higher temperatures that this particular Rainbowfish enjoys. Sadly, the Boeseman’s Rainbowfish is listed as Endangered on the IUCN Red List of threatened species. This is due to fluctuations in water levels/conditions in the natural habitat and over-fishing. The vast majority of the specimens offered for sale in the shops these days are captive bred. May also be seen on sale as Boesemani Rainbowfish.
