Is a nudi a bad thing?
Excellent way of putting itLets hope its not a nudi thenIts 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.
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.
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.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!
