Raubturmdeckelschnecke - Clea helena
Reference S089 · Zündorfer Aquaristik NZ
Animals and plants differ in their demands on water parameters, tank size and tank mates. Please check the details in the tabs below before you buy. If you are unsure, just get in touch before ordering — we are happy to advise.
The shell of the assassin snail is conical to slender tower shaped, 18 to 28 mm high and 7 to 13 mm across when adult. The base colour is yellow to olive brown, either plain or with up to three brown spiral bands.
Shell shape, ornament and pattern vary strongly within the species; the six to eight whorls usually carry axial ribs. Clea helena feeds on other snails and is therefore used deliberately against snail outbreaks.
