This is a very effective snail trap!! It’s a fascinating design, that is, honestly, a bit fiddley to set up, but it is the most effective snail trap I have used. Tiny fish/fry could get inside, so take care when removing from your tank.
The only reason I give this product 4 stars is that my plecos were able to find their way into the trap even when I had it set with the smallest opening. I like the design and it is built well but be careful with smaller fish in the tank.
The snap trap works really good .
I have several tanks where I have made homemade snail traps, and always skeptical of new products, but I bought the Sera snail trap. And I've never found anything that work better than this! Follow the instructions baited it a few hours later it was completely full. And I use snails to feed my big fish. Highly highly recommend
It gets the job done on collecting all my extra snails
