Ok, so when I turned my light on this morning I saw a white tube coming out of one of my new tonga or fancy nassarius snails. It sucked back in as soon as I saw it. No pic:-(. But I went to a lfs today and ironically I saw what appears to be the exact same thing hanging out of an orange spotted snail. This one did not suck back in. Even after I asked the owner to disturb t he snail to see if it would. He even picked it out of the water and it just stayed hanging out. Anyone know what it is?
