🐌 Assassin Snail (Clea helena)
🐌 Assassin Snail (Clea helena)
Freshwater Carnivorous Pest-Snail Predator • Genuinely Not an Algae Eater • Natural, Chemical-Free Snail Population Control
📋 We want to be genuinely upfront: unlike most snails, the Assassin Snail is genuinely carnivorous and does not eat algae at all. Instead, it's prized for hunting and controlling unwanted pest snails, such as bladder, pond, ramshorn, and Malaysian trumpet snails, offering a genuine chemical-free solution to snail overpopulation.
This species genuinely spends much of its time partially buried in soft sand, emerging to hunt, and is recognizable by its distinctive yellow-and-brown banded, elongated shell.
We want to be honest about shrimp compatibility too: adult shrimp are genuinely safe, but baby shrimp and freshly molted, soft-shelled shrimp can occasionally fall prey given the chance. This species will also genuinely eat fish eggs, so it's best avoided in tanks where you're raising egg-laying fish.
