A baby water snail has appeared in my fish tank. I have no other snails/plants, so where has it come from?
My fish tank currently has 5 leopard/zebra danios, one black moor, and 3 mountain minnows. It previously has a sucker fish and another black moor but sadly they died. I also previously had 3 live plants in there. The snail has just appeared but where has it come from, and will it survive?
