Hi All I purposely introduced the Malaysian snails into two tanks after reading their benefits in keeping the gravel loose. After a few months they populated the tanks to such a degree that I realized the error of my ways but didn't want to chemically remove them due to the fish I had in the tank. I added a Leporacanthicus galaxias, one of the Vampire Pleco's to the tank and the Malaysian snails disappeared. The galaxias do dig in the gravel for hours so they may not be the best for a planted tank. I wasn't sure if the galaxias was really the snail killer, so I bought a L. heterodon for the second tank and had the same result, no more snails. It seems to be the best "natural" solution to a Malaysian snail problem and you will have a beautiful Pleco in the end.
