HELP! My Tank is infested by some slugs!

[Earthborne]

Help.... My tank is infested recently with lots of creepy slugs like creatures crawling along the glass. I desperatly use the alge-magnet to squash them when I can reach them. However, they infested 2 of my button corals. One rock of buttons failed to open at all because of all these critters crawling on it.

These slugs seems to be 2 mm to abt 8mm in sizes. I guess some kind of nudibranch?

They had butterfly wings like appenadages along the body. Baby ones whitish, adult ones greenish.

Any folks can offer advise?

Anything to eat them up?

I'm desperate.

Thanks.

Get all of them out.. They are nudibranch... And they love buttons... Got to kill them.. Remove all yr buttons from yr maintank.. and try to catch the rest.

Do it fast. They multiply real fast. Damn productive.

Yes, they like buttons, got to throw away one of my favourable.

They dun live very long, I left mine alone and after a few weeks (after eating away my button polyps)... they disappeared.
