Howdie has anyone got any idea what this.It cam out with the lights off(only blue lights on) and gapped quite fast when the light on my cell came on to take a photo.

Goodisor - rather remove it.... I am not 100% sure, but something VERY VERY similar killed a carpet anemone of mine...... It actually ATE about a third of the nemmie, then the nemmie died......

Looks like some type of Nudibranch, however a better pick would be needed to make a positive ID

Im sorry but these are just as bad at least you can see the shape.He has been eating all the brown algae covering that particular piece of biorock.
Jacques,I went immediately to take him out but he has dissappeared again,I will have to keep my eye open for him

Is a nudi a bad thing?
Its like asking whether a man with a gun is a bad thing?... Depends is he protecting you or trying to kill you?

Some are good but not all, and the bad ones do much more harm than the good ones do good.

I don't think it's a nudi... I think it's a snail... but better pics are needed.

I have a couple of these guys (or they look like yours) in my tank.
So far so good. (I've spotted them for over a year now).
It might be that they are not the same as yours.
But as soon as you shine a torch on them, or switch the TV room's light on they're gone...
And boy - they can move!
They are always "gracing" on my LR. So I recon mine is good.
Good luck!

I think from looking at him for a while now he definitely matches the Scutus or elephant slug description.That last pic from the link I posted is identical.

Yep... told you... it's a snail. Even though it's on the "Slug" forum, the Scutus sp. are actually snails. ;-)

Btw, I LOVE these guys... I've even bought them.

Thanks Sihaya.I feel like I can breath again.

Shot guys for the very prompt replies.I will try and get some better pics if I can.I just dont have anything that takes a decent photo in the dark.

Yip Raven,you are right they can move quick when they want to.As soon as my camera light switches on to take the photo he starts to move rapidly behind a rock or something.

Actually... with the better pics, I don't think those are Scutus. Looks like an all black Stomatellid. Cool!
