''Cryptoheros septemfasciatus'' (sometimes called the Seven-stripe Cichlid or Cutter's Cichlid) is a fish species in the cichlid family. It is found on the Atlantic slope of Costa Rica, between the San Juan River drainage and the Banano River.〔(【引用サイトリンク】title=Cryptoheros septemfasciatus )〕 Several currently recognized cichlid species within the genus ''Cryptoheros'' were formerly considered varieties of ''Cryptoheros septumfasciatus'', including ''Cryptoheros myrnae'', the Topaz Cichlid, and ''Cryptoheros cutteri'' (which also sometimes uses the common name "Cutter's Cichlid"). Prior to being placed in the genus ''Cryptoheros'', it had been considered a member of the genus ''Archocentrus''. Within ''Cryptoheros,'' ''Cryptoheros septemfasciatus'' is placed in the subgenus ''Bussingius'', along with the T-bar Cichlid and several other species.〔〔(【引用サイトリンク】title=Convict and Jack Dempsey placed in new genera ) 〕 However, a 2008 study led by Oldrich Rican has suggested that all the species in ''Cryptoheros'', including ''C. septemfasciatus'', should be moved into the genus ''Hypsophrys''. ==Natural history== ''Cryptoheros septumfasciatus'' grows to between . Males are typically larger than females.〔 Both sexes generally have six vertical bars along each side.〔 Females have a black spot or ocellus on the dorsal fin, which is generally surrounded by metallic coloration.〔 It lives in rivers on the Atlantic slope of Costa Rica. It can be found in rivers of all velocities, including slow moving and fast moving rivers.〔 The bottom of the rivers it lives in are generally covered by rocks and leaf litter. In its natural habitat, the pH is generally between 6.6 and 7.6 and the water temperature is between 21 and 27 degrees Celsius (70 to 81 degrees Fahrenheit).〔 Its ability to protrude its jaw 3.5% standard length limits its diet to about 1% evasive prey. ''Cryptoheros septumfasciatus'' is an egg layer and a cave spawner. In breeds in crevices in the rocks at the bottom of the river. Spawnings typically result in 200 to 250 fry.〔 The conservation status of ''Cryptoheros septumfasciatus'' has not been evaluated by the International Union for Conservation of Nature (IUCN).〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cryptoheros septemfasciatus」の詳細全文を読む スポンサード リンク
