1、准备一个45＊45＊45厘米的繁殖缸，水位到40厘米（野生的神仙用60*35*50厘米水位到55厘米，因为野生的比家养的体形大一些。），用困过7天的水就行，但水温一定要与养缸一样。
2、在放入亲鱼前加入50克食盐。用一片毛玻璃或磨沙玻璃，与缸壁成19～30度角。
3、光照：自然光即可！最好是把繁殖缸放到北面，避免阳光照射。
4、水温：繁殖水温以26度最好（红眼钻石、墨神仙与金顶玻璃神仙为28度，放鱼后再调水温）。
1.才产完一般不会吃，但是不排除有吃卵的。最常用的是提板法，就是放一个产卵器进去，或桶状或板状，鱼会把卵产到上面，然后找一个小缸，最好是不超过30厘米，装原缸水一半，爆好的新水一半，水里打一支庆大霉素杀菌两分钟后，把产完的卵板放到小缸里，用一个气头加氧和增加水的流动，卵和小鱼是不怕水流动的，然后就是温度了。温度高出来的快，但是体质差一点。25度左右最好。出来后还是粘在板上的，不用管，再过3天左右就会起飞，也就是会游泳了，这时候就要喂食了，我们一般用无节丰年虾幼体来喂养，也就是俗称的虾卵，孵化好了就可以喂了，还可以用洄水，也就是草履虫和轮虫。吃上几天就可以吃小些的鱼虫了。
2.燕鱼是一对对的,要取一对成熟的亲鱼,单独放在一缸里,放一小块玻璃板在角度里,直至小鱼孵化成功以后!
亲鱼会用自己的体液喂小鱼苗一段时间,等小鱼再不吃亲鱼体表的体液以后,将亲鱼捞出!
3.可以成活的鱼卵是淡黄色,半透明状的.
鱼卵变白说明鱼卵已死,或者本身就是废卵,也就是说,雌鱼产的卵并没有通过雄鱼受精,所以只是废卵.
如果是受精卵,那么你对燕鱼的繁殖方式有些误解.
只要把一对亲鱼与其它鱼先隔离就可以了,产卵后,双亲鱼会精心照料受精卵的,并经常清除产卵板上的杂物或变白色呈棉花状的废卵.受精卵约经2-3天后即可孵出仔鱼,刚孵出的仔鱼不游动,双亲鱼继续用胸鳍扇动仔鱼,如果仔鱼掉落板下时,亲鱼就用嘴含起再吐到板上.在此过程中勿惊动亲鱼,否则它们有可能吞食卵子和仔鱼,所以饲养它们的水族箱应放在较安静的地方.当仔鱼可以自由活动时,再与亲鱼隔离,喂经过过滤的鱼虫等.经10多日后幼鱼就具有与亲鱼一样的外貌了.
如果你实在不放心,也可以把鱼卵板单独放入孵化缸,但一定要安装一只自动充气机进行人工孵化.保证水温28度以上.
方法找到了3种，现在就看你如何去面对了。
