罗汉鱼怎么养?需要吃什么的?

罗汉鱼的喂养方法:养殖罗汉鱼水族箱,最好尽可能地使用较大的水箱(60公分或以上),这样有利于鱼长成较大的个体,并促成较佳的头型。由于罗汉鱼生长迅速,排泄物也相对较多。因此,最好加设一套有效的过滤系统,能确保水质的洁净,这样可以大大降低鱼病的发生。加一些增氧设备(如气棒,生化棉筒等)。也可根据个人喜好,在缸底加铺底砂,模拟一个接近自然的生态环境,会使鱼更安心,并刺激鱼发情,同时达到增大头形的效果。罗汉鱼最适宜水温在26~30℃,其中以28℃为宜。在养殖过程中一定要避免温度的突变,温差不宜超过±2℃。水体最好为无色透明、没有浑浊物。罗汉适宜生活在PH为6.5~7.2的水体中,在PH为6~7.8的水中也能生活,但超过这个范围就会影响到它的生长。如果水中的酸碱度较高,可以加入磷酸、沉木、软水树脂等,把pH慢慢调低。若PH值太低,则可以加入珊瑚砂,可使PH值慢慢提高。饲料,一般可以使用生饵,小虾、赤虫等,以及不含人工色素的饵料喂食均可。投喂量要相对固定,不能忽多忽少。一般投饵量为罗汉体重的1~2%比较适宜,并根据罗汉的大小、摄食情况、以及季节变化等来决定投喂的饵料量。每次不要喂太多,使鱼在10分钟内吃完为宜。平时喂食时要注意罗汉鱼的反应,当食欲减退时要停止喂食。
