Assassin Snail
宝塔螺
Clea helena is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Buccinidae, the true whelks, most of which are marine.
This species occurs throughout southeast Asia, especially in Indonesia, Malaysia, and Thailand
Like all snails in the clade Neogastropoda, it is carnivorous. It feeds on worms and gastropods, and is often known as the "assassin snail" for its habit of eating other snails.

该螺不吃水草,但会捕食其他螺和动物尸体,固有杀手螺之称。但不会攻击鱼类,所以可以作为很好的除螺工具了。如果水草上长蜗牛可以用该生物除去,而免掉用河豚除蜗牛对鱼类造成的威胁。很好用的工具螺。蜗牛不足时以藻类,饲料残渣,动物排泄物为食。不可与其他螺类混养。
