-- [ From: Gene Bauman * EMC.Ver #2.5.02 ] -- Not to beat the snail subject to death, I have a quick question and then will shut up. I just got some mail-order pond snails "Black Japanese Trapdoor Snails - Viviparis malleatus" and one has two small almost circular holes in the shell. What is this a symptom of? The treatment/cure? Thanks, Gene
