@gerbilbox Right on.... SC = suncorals. I have a tank full of SC's and Dendro. On a side note for the snail, read here http://www.nudipixel.net/species/epitonium_billeeanum/ http://rfbolland.com/okislugs/tubastr1.html
SC = Sun Coral? It looks like Epitonium billeeanum, which only eats sun corals. I'm not a snail expert, but I happened to be browsing Calfo and Fenner's "Reef Invertebrates" and it has a picture that looks very much like your snail.
Interesting. What the heck is that?
yellow nassaris?
What type of snail is that?
