鱼类繁殖各个不同形式中, 最拟人化的我想应该是斗鱼吧, 不管是泡巢或口孵的方式, 因为其中包含了 ”公鱼拥抱母鱼” 的动作, 这是一般体外授精的鱼类所没有的. 当母鱼有意愿想配对时, 母鱼会对公鱼所做的泡巢露出兴味的模样, 在公鱼忙碌的浮上水面吸气做泡巢的同时, 母鱼也会进出泡巢的下方, 像是评查公鱼泡巢的工作进度一样, 也像是在满心期待它们爱的小窝完成的样子, 而公鱼在母鱼游近时也会展开全身美丽的鳍向母鱼夸示, 母鱼离去它又开始忙碌的工作.
当一切准备工作就绪, 公母鱼就会浮着头在水面开始绕圈圈, 经过几次的尝试, 公鱼弯着腰呈U字形的抱住母鱼, 并将母鱼反转腹部向上, 二者同时射精并排卵, 当公鱼看到一颗颗晶莹的卵粒向下掉时, 就会急忙的放下母鱼, 去将卵一一衔入口中, 并将这些未来的小生命细心的塞入泡巢中, 此时母鱼也从欢愉的晃惚中清醒过来, 短暂的展鳍夸示后又绕着圈圈反复交配的动作. 通常这样的时间会持续三到六个钟头, 等完成后公鱼就会将母鱼赶走, 独自一人照顾它们的宝贝蛋.
温度如果在二十八度上下, 小斗鱼在48小时左右就会孵化了, 刚出生的小斗鱼还不会游泳, 每只都头上尾下的黏在泡巢上, 即使掉在缸底一有风吹草动也会奋力的往上游, 等小斗鱼打横我们就要来帮它们准备食物了, 孵丰年虾苗应该是最方便的, 笔者都是用这个方法, 当然也有许多同好, 有许多不同的创意, 像淡水水蚤就是不错的方式, 许多浮游生物也都是很好的小鱼饵料. 只要注意适口性及对水质的影响就不容易出错了.
第一次带小斗鱼是用所谓淡水虾苗的粉末饲料, 虽然弄得很麻烦, 不过那次也带大了一百五十只左右的小斗鱼, 只要细心其实都没问题. 不过大家会碰到最多人建议的绿水, 反而养活小鱼的机率不高, 可能只有五到十五个百分比, 大概二三十只吧, 这是因为小斗鱼是肉食性的, 绿藻对它们没有帮助, 绿水中吃绿藻的浮游生物才是小斗鱼的最爱, 不过量都太少了, 对这些刚出世的大胃王是绝对不够的.
如果喂食正常,小斗鱼出世一个月左右就会有零点八公分左右了,如果您繁殖的是双尾斗鱼,大约七到十天大小斗鱼就可以看出来是双尾的,鱼的尾巴可以看出来是ㄚ字形的,非常可爱。正常的喂鱼及换水就如同一般养鱼的要领一样,三个月大时,公鱼的性征就会一一显现出来,甚至开始吐泡巢,公鱼鳍变长的顺序是臀鳍、背鳍,最后才是尾鳍;如果臀鳍往下拉长并往后拖出尖尖的形状,就可以捞出分开饲养。
鱼没有怀孕期,繁殖的时候就排卵了,在体外受精,一天一夜后鱼卵开始孵出小鱼苗
根据气温1-14日不等。尽量维护水质,繁殖后捞出母鱼防止其食子,小鱼孵化后,将公鱼捞出。水质非常重要,一但水质败坏,可能导致不出鱼。水质,气温,动态情况。都会导致不出鱼。
