So a while ago I was on break at work and had to go get a smaller siphon for water changes and I saw that they had a nassarius snail. My tank had just finished cycling so anyway I got him and the guy gave him to me for free by he didn't know if it was dead or alive turns out he was and I'm not sure if it's a nassarius snailor not. He spends most of the time on the glass and not in the rocks or sand bed I aso tried feeding him squid my last one loved it but this one seems to not and his shell's oddly shaped. I see his little siphon behind the glass but never saw it outside his shell... anyone have any thoughts on anything? This one is just kinda stumping me
