The first time I dropped the ISTA Snail Trap into my aquarium, I was surprised by how lightweight and compact it felt in my hand. It’s about 2 inches across and less than two inches tall, so it fits neatly into tight corners without taking up much space.
What really caught my attention was the bait chamber. It’s cleverly designed to attract snails with minimal fuss — no chemicals needed.
I simply added some of the provided bait, placed the trap near a known snail hotspot, and watched a few curious snails crawl right in.
Using the trap is super straightforward. The air hole design helps it sink naturally to the bottom, and the fishing line makes pulling it out a breeze.
