半月斗鱼的外形特点
半月斗鱼(详情介绍)

  半月斗鱼(详情介绍)一半可以分为HM(half moon)和OHM(over half moon)两种,HM就是指半月斗鱼的尾巴展开的时候能够达到180度,形似半个月亮的样子,而OHM则是斗鱼的尾巴展开时能超过180度。一般OHM为HM中的极品。半月斗鱼一般成鱼体长在8-10公分。

  半月斗鱼虽然也有斗鱼好斗的习性,但是经过观察,他们大多能和小型热带观赏鱼能和平相处。半月斗鱼的主要特征是有一特别呼吸器官,称之为“辅助器”,用来呼吸空气,它能够在水面吸一口气送入辅助器里,进行气体交换。斗鱼体背栉鳞,背鳍和臀鳍均延长,鳍棘部长于鳍条部,腹鳍第一鳍条延长成丝状,它的身体为浅褐色,具10条左右蓝色或绿色横带,眼至鳃盖带有2-3条暗色斜带,鳃盖后缘具一蓝斑。它能栖息沼池、沟渠的污水中。
