The red Bulu Point Petrochromis is said by some to be surprisingly lacking in the aggression characteristic of other cichlids. Females are a bit duller, with a brownish top and mask and a pale orangish belly and cheeks. Adult males are hot orange or red in overall color, often with a dark mask across the face. That is quite understandable, as it is an unusually colorful fish. However, it is quickly becoming a sensation among African cichlid enthusiasts. Little is known of the biology of this native of Lake Tanganyika, Africa. Petrochromis “Red Bulu Point” ( Petrochromis sp.) Known as somewhat fickle (at least for a catfish), it is usually kept only by experienced aquarists in well-established aquaria. Sharp, black stripes run mostly lengthwise across the body vertical stripes run just behind its eyes and along its shoulder through the pectoral fins. Though it is shy and is not always easily viewed in the fish aquarium, it can be an extraordinary sight to behold. They are considerably more expensive than their common “pleco” cousin, with even smallish individuals easily selling for around $250 each. Originating in the Xingu River of Brazil, captive-bred specimens of this highly prized fish have become available. This species was first described only in the 1990’s. Individuals sell for around $225 each however, experts have advised that this highly social species be kept in groups of around four or more individuals per tank.

Therefore, it is imperative that any aquarist that stumbles upon this very uncommon animal ensures that it is captive-raised before making any purchase. This odd loach comes from clear, well-oxygenated parts of the Yangtze River system, where it is under serious threat due to the construction of dams on the river. It sports a bright golden background color and dark, erratic blotches. And, it has a somewhat flattened head with little, beady eyes. Firstly, it can easily exceed a couple of feet in length. Imperial flower loach ( Leptobotia elongata) It should be noted that the term rare is here used to indicate rarity in the trade, not necessarily in the wild one should always avoid wild specimens of threatened or endangered species. Rarity may be defined by very narrow (albeit totally absolute) criteria for example, while most koi retail for $10 to $20, exceptionally well-bred individuals often sell for tens of thousands of dollars at auction. The following is a mere sampling of some notable, rare freshwater aquarium fishes.

Of course, demand for some rare species is restricted to a mere handful of specialists, and accordingly commands only a slightly higher price (certain killifishes, rasboras, etc.). In point of fact, some of these freshwater rarities are among the most difficult and costly to obtain in the entire ornamental fish trade. While it seems that there are countless “holy grail” saltwater species, the freshwater side of the hobby has its own share of unusual, much sought after fishes. An increasing demand for rare fish has coincided with this trend. Despite the occasional economic downturn, fishkeeping (and indeed the aquarium industry) has steadily grown over the last half-century.
