This past summer I have a huge snail infestation in 3 of my tank. And I'm worried about a 4th tank as I found 3 snail in there now. I tried 3 dozen Assassin Snail which died off before they could really do any dent into the infestation. In one of my tanks I got some Clown Loaches and it didn't seem like the snails were fading, so I picked up 3 Yoyo Loaches and within a week, I hardly see any snails crawling up the glass now. Unfortunately, they are way too small to go in the other tanks, but it seems that Yoyo Loaches are the way to go.
