deland,
你还要不要金鱼了，我有一只，想送人，然后养discus,犹豫中。听说discus很难养，另外我只有20
gallon,据说discus必须至少养3只。

鱼缸里的设备大同小异，不外乎就是循环、增氧、调温和调光四种，说白了就是水泵、气泵、加热器和荧光灯，水族行和金鱼店都有卖的，价钱也不贵，根据鱼缸大小、鱼的种类和个人喜好去选择，用过几次就有数了，没有什么固定的说道．
稍微发绿的水是好水，绿色的是单胞藻类，但太绿了就不好了，单胞藻类过量，死亡的单胞藻尸体会败坏水质，耗氧和引发疾病等，解决的办法很简单，把光线调暗一下就可以了，如果发现的较晚水已呈深绿色，那就得换水了．
鱼缸的壁也是稍有一点绿苔好，换水时，如果鱼缸里没有传染病菌，或者鱼缸的壁不是太脏，尽量不要刷它，用清水反复多冲几次即可，如果担心美观，可采用稍微有点颜色的玻璃缸，或者在鱼缸背面贴上较深色（比方说绿色或兰色）的背景纸，光线尽量不要直接照到正面的玻璃上，通过背景纸上反射到缸底，一般看起来水就很清了．
残饵和粪便不要通过换水来解决，要用管往外吸，吸底前要把循环水和充气泵关一会，静一下让脏物沉到底，最好每天都吸底，吸出的脏水不要倒回去，要倒掉，添加新水，添加的新水要事先困两天，爆爆气，新水与旧水的温度要尽量保持一致，不得已的情况下才彻底换一次水，如果换一半能解决问题，就不要全换．
如果循环水带过滤器，残饵和粪便基本上通过循环水滤在滤膜和砂子上，一星期清洗一次滤膜或砂子就可以了，会省不少事．

Seems that more and more people talking about fish now. Understand that the fish field in Montreal is very backward comparing to Toronto. But if people can help each other, at least it can developed.
简简单单 If you are looking for high end good quality flowerhorn, you can PM me your plan. I might be interested. Actually price in Toronto is not expensive. 200~300 for a pretty nice color one. Over 700, you can get a decent quality one. I don't think you can find good quality flower horn in Montreal even in aqua tropical.

别为孩子养鱼了，养鱼很贵，也很费时间。只有自己真正喜欢才划的来

I think it's better to go and buy from Toronto, at least you see what you will buy. If more people is interested, then we can buy more in one time from the dealers (compare one by one if possible) in Toronto to get better price.
For how to keep fish good, different people will have different comments. General speaking, I personally don't want to set up too much regulations here, which will stop the potential beginners to try.
In my opinion, keeping fish is not difficult as long as you know how to maintain the water parameters for different fishes.
Above is only my 2 cents.

养鱼比养其他宠物好啊，安全，干净，卫生，加拿大这旮旯，冬季本来就干燥，又是木结构的房子，老外身上毛长不在乎，亚洲人还真是有点受不了，早晨起来嗓子真冒烟，屋里放缸观赏鱼，即美化了环境，陶冶了情趣，还有调节空气的作用．
老外见了要晕了哈export_pic.jpg (0 Bytes, 下载次数: 562)

看来各位和我想的不一样,我想在自家池塘里养鱼
Post by deland
讨论的挺热闹，关于水泥池如何防渗，本人略知一二，供参考：
1，素灰防渗，顾名思义，我们通常给水池内部罩面时，用的都是砂灰，砂灰就是砂子和石灰混合，就是我们通常说的水泥，素灰就是不兑砂子的纯石灰，砂灰强度高，但防渗不好，素灰防渗好，但强度不高，具体方法是，先用3:1的粗砂水泥找平，中间抹一层的素灰，最外面用一层2:1的细砂水泥做防护，这是三层防渗，如果精益求精，可做五层防渗，靠近素灰的里层和外层都是1:1的精砂水泥，最里层和最外层的不变，最好的六层防渗，也就是在防护层内，1:1的精砂水泥和2:1的细砂水泥之间，再加一层素灰，最多六层，再多就没有意义了，注意每层都要干透以后，经过水泡养生再抹下一层，做到每一层既要界限分明，又不起两层皮，挺费事的，一般的泥水匠做不了这活，得请个高手，而且工钱要多很多，通常每加一层，都要出一份同面积的钱．
2，贴玻璃钢，水池内部水泥罩面找平以后，买一种叫做酚醛树脂的东西和玻璃丝布，先刷一层树脂，贴一层玻璃丝布，一般只要一层就够用的了，但要注意不要有遗漏，如果水泥池很简陋，可以多贴几层，有加固的作用，酚醛树脂和玻璃丝布都不贵，只是做起来费事，但既然折腾上了，多几层少几层都差不多，不如索性多贴几层，为了美观，贴好后可刷一层带颜色的树脂，就是以前的树脂，兑点你喜欢的颜料就可以了，注意一定要干透并且味散尽后再泡水，而且一次性泡一星期以上，如果一次没处理好，以后总是泛油，这个池子就废了．
如果有条件做素灰防渗外加一层瓷砖，是最牛的，只是加了瓷砖会引起一些新的问题，说来话长就不罗嗦了．

有没有特别好养永远也不会死的鱼？

养鱼主要是养心情.

2、海象，海象也生活在亚马逊河流域.此鱼嘴部没有龙须外观和其它的龙鱼根本不相似,但却属同科兄弟。海象体长可达5米,重约半吨,真可谓巨龙也!海象无法养在水族箱里,只能饲养在大水池中,国内很少人饲养.但在日本,却曾经受到爱鱼者的追捧.不过,在喂它的时候可得小心啊,小心不注意时少了只手!
