    There was a CO2 accident again with my tank last Saturday. The CO2 needle valve was turn to maximum and killing most of the tank inhabitant. From 20 espei, only 2 survive, amazingly all the Yamato and Cherry survive.

    The interesting part, it is also killing the pest snail, those tiny flat slightly transparent snail, below 2-3mm long. This snail is hard to handle, because they can hide anywhere and stick to the glass in the morning.

    So I was thinking does anyone try eradicate pest snail using CO2? Remove all the fauna and blast it with CO2 . I'm not sure if it work on any tipe of snail, it may also work for planaria.

    Ghost shrimps, puffer fish, khuli loach can all eat the snails and keep them under control.

    What about if the Co2 blast is so great that it kills all your beneficial bacteria? You have to start from ground zero again.

    It probably does , but still better than redo the whole scape again.

    wild bettas/parosphromenus also eat snails, to my surprise and delight. after adding a pair of wild bettas and a group of wild parosphromenus into one of my nanos that had a slight snail problem, i started seeing whitened empty snail shells littering the hairgrass, and no more unsightly snails on the glass

    The parosphromenus have reduced my blooming red ramshorn snails population from over 50 to just a small bunch, and lots of empty shells.

    That said i think sudden deaths of so many snails using co2 may just cause your tank to crash with so many dead snails rotting away, unless you remove most of them after they die.

    Sometime you can't just put fish to control snail because it does not mach aquascape theme you want to achieve. For example in my case, I want only school espei in my tank. The dead snail probably will be eaten by my Yamato and cherry.

    At this moment, I do not add new fauna into the tank. I'm thinking to let BB colony stabilize for couple of weeks.

    It is interesting to know that Yamato and Cherry shrimps is more resilient than espei. Is it because espei is keep moving thus need more oxygen?

    i think you can just put a mini puffer fish in first, when all the snails are eaten.
    you can give the mini puffer to someone else

    i second tcy81's opinion. by far, it is the most effective and most natural way of killing these pesky snails without drastically altering water parameters. if the population of the snails are rather low, the puffer fish might start nipping or cannibalising your other prized fish to fill its stomach!

    my preferred method of removing snails is always manual removal. of course, you should start doing so before the population explodes!
