Green snail?

[sanhas]

Hi,

I'm new to marine set-up. Recently I've seen 3 green snail(I think) inside my tank. I've removed these creatures. Anyway, I wish to know what exactly is it? Is it harmful to my tank environment? Thanks in advance

A picture tells a thousand words. show a picture for better identification.

Snails can be both good or bad...

Thanks for the valuable link. From the pictures...it looks like Sacoglossa slug and Tiger cowrie. Are they a pest and dangerpus. Once again thanks.

those two you mentioned are not reef safe. Do be careful if you are intending to keep corals.

Thanks for the advice. I wonder if its ok for me to remove them with hands? The big one seems scary for me?!
