Yes I agree with you, snails can transmit diseases, living in black water hardly snails and other micro-organisms have it too hard. I have not yet lost no Paros by parasites, rather byreacting and injuries while catching out even though I several times a week, my own food which also include native fish catch in different waters. Paros are in good care really tough and more likely to die of old age as from diseases. 🙂
