''Laetacara'' is a small genus of cichlids native to soft, acidic freshwater habitats in South America. The genus is also collectively known as the smiling acaras.〔 The range of the genus extends from the upper Orinoco River in Venezuela to the Paraná River in Paraguay.〔Linke H, Staeck L (1994) ''American cichlids I: Dwarf Cichlids. A handbook for their identification, care and breeding.'' Tetra Press. Germany. ISBN 1-56465-168-1〕 Like all cichlids, ''Laetacara'' species have well-developed brood care. All members of the genus are monogamous, open spawning cichlids.〔 Most species are popular in the fishkeeping hobby and are frequently kept in aquariums.〔 ''Laetacara'' species are relatively small cichlids, growing from 5-10 centimetres (2-4 in) in length and are part of the group known to aquarists as dwarf cichlids.〔 ==Species== There are currently six recognized species in this genus: * ''Laetacara araguaiae'' Ottoni & W. J. E. M. Costa, 2009 * ''Laetacara curviceps'' (C. G. E. Ahl, 1923) (Flag acara) * ''Laetacara dorsigera'' (Heckel, 1840) (Redbreast acara) * ''Laetacara flavilabris'' (Cope, 1870) * ''Laetacara fulvipinnis'' Staeck & I. Schindler, 2007 * ''Laetacara thayeri'' (Steindachner, 1875) 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「Laetacara」の詳細全文を読む スポンサード リンク
