What is this beast

[FishypantsMitch]

I have had this “snail” that my old LFS sold me they said it’s a nassarius snail but he is way bigger than all of my other nassarius snails he has also started to attack my other inverts at night like smaller snails and hermits if someone could identify this snail for me it would be a big help thanks

I do not know many snails, but maybe an olive snail. I think they are predatory and I would get it out. Especially if you are seeing it go after other cuc.

Turn off the blue light and take a pic with only whites on.

 

[ScottR]

All I can see is blue and an outline. So my guess would be cone snail. But agree that whiter pic is needed

+1 or use a flashlight, def not nassarius snail. Look like this?:

Yes need a clear picture.

That is a Lettered Olive Shell. They are predators, but depending on what you have in your tank, they are pretty cool to watch. Throw a piece of dead shrimp in the tank and it will come running (if it had legs!)

Okay I’ll wait until he pops back out and snag another pic thanks for all the help

 

[K7BMG]

Time to scoop him out then.
Take pic outside of tank.
Put him back in.

Just did a quick search on YT and yup that is definitely it do you think I should remove him I have a 13.5 nano reef
1 clown
1 yellow watchmen
About 5 nassarius snail
10 red hemits and a few other snails

It is not a cone snail. And a good thing it is not, they can be dangerous.

Lettered Olive shell, Oliva sayana .

 

[ScottR]

If truly a cone snail, they can kill humans. So be careful.

 

[K7BMG]

Just take him back.

 

[FishypantsMitch]

Just take him back.

I don’t think I can take him back. What should I do. And also how should I remove him even if he is a olive snail.

Can you take a net and scoop out of the sand?
