翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Dither fish ： ウィキペディア英語版 Dither fish The term dither fish refers to an arbitrary group of aquarium fish used by cichlid keeping aquarists to reduce innate timidity in some species of cichlids.〔Barlow, GW (1968) Dither--a way to reduce undesirable fright behavior in ethological studies. Z. Tierpsychol 25:315-318.〕 Dither fish typically swim around the top of a tank and this behavior encourages more timid fish to relax and venture out more by reassuring them no predators are around. The technique relies on the ability of cichlids in an aquarium to use the behaviour of other fish species as a measure of environmental security.〔Loiselle, PV (1979) On dither fish. ''Freshwater and Marine Aquarium Magazine'' November:30-34, 76-79 (also (online )).〕 Good dither fish are typically schooling species, such as some ''Danio'' species, barbs and some tetra species. ==References== 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「Dither fish」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
