Please help me identify this guy before I move him into my display tank. He came with a full tank purchase. I don't want anything that will eat my corals or other tank inhabitants or harm me!

Now I'm thinking possibly Nassarius olivaceous.

It shouldn't be harmful. It does look a lot like N. olivaceus, although the lip profile is a little odd. Maybe subadult.

Thank you! I'm sorry it's not the best pic, I've read a lot about the venomous cone snails lately and was scared to stick my hand in there to get him. I can try to take a better pic tomorrow.

You seem to be the go-to for snail info so do you know if Nassarius and conchs require a sand bed to survive if there is detritus and algae within reach for them along with supplemental feeding? I'm currently running an 85 gallon bare bottom and sort of dreading adding sand because I don't want to be constantly knocking it off of corals or readjusting powerheads. But I also don't want them to starve to death. I guess I have 2 nassariuses and 1 fighting conch (I think. Has the switchblade foot if that matters).

Also, best snail to live in quarantine/frag tank? Not running filters, just some live rock, heater, power head and water changes. 10 gallon for now.

It's definitely a harmless Nassarius, although I'm not 100% certain which species. Neither conchs nor Nassarius absolutely require a sandbed, although most nassarius species do burrow in the sand. Several conch species actually live in coral rubble areas with no sand, but the smaller species normally seen in the aquarium trade usually prefer muddy sand areas (Conomurex luhuanus, the "Tiger Conch" of aquarium suppliers), or clean sand with some vegetation (Florida Fighting Conch, Humpback Conch, and others).

Thanks for the confirmation and info!! I guess I'll just watch them and see how they do. Anything I should look for if they are unhappy or declining in health? There are some areas up under the rocks that get a bit sandy and are collection spots but it's not a lot.
