Early this morning I found several small snails eating the Pak Choy seedlings in one of the growbeds. The snails are tiny cone shaped, not like the common garden snail. I removed about six of them from the seedlings but when I tried to pick up some of the snails on the surface of the clay balls, they just dropped into the grow bed.
Can anyone suggest a method of removing the snails without using something that might poison the fish or plants?
I think these snails may have come into the system via water hyacinth. I don't think they have climbed up the grow beds as they are too high.
I know a few tricks to stop the common garden snail or slugs in a soil garden, like using ashes around the plants etc. I am sure that there will be too many of these pests to just pick them off the leaves every morning as they are so tiny I assume they are part of a litter, so probably hundreds of them in the growbed.
