涡虫,在草缸里几乎各种灯鱼都会去主动捕食,相对比较好对付。但是囊螺和扁螺就比较烦人了,长得快,繁殖快,扁螺还好,囊螺甚至还会啃食水草嫩芽,对于它们,用药或许是见效最快的方法,无奈是药三分毒,加上市面上水族用药这个乱…生物治理还是最安全的办法。
巧克力娃娃这种鱼没说的,螺类终结者,可惜有趁夜色偷袭其他鱼类鱼鳍的恶习,而且对虾威胁极大。所以我这里选择使用另一位文雅一点的杀手——大黄蜂螺,俗称杀手螺。
和大多数螺类一样,白天它基本都躲在泥土中或沉木的缝隙里安眠,当夜幕降临之后才会活跃起来

首先是不少朋友缸中都有的扁螺~
据我的观察,杀手螺的探测半径大约在10CM左右,只要猎物进入在这个范围内,它们都能很快的察觉,下图详见杀手螺捕食扁螺的全过程,杀手螺平时露出的长管其实是呼吸管,同时貌似也有嗅觉的功能,总是会朝着猎物方向,而一旦抱住猎物,仔细看图,你会发现除了呼吸管,它还有一条细长的管子,那就是它平时隐藏起来的口器,
