Slugs

Are they harmful to reefs ?

Depends on the slug. Some are, some aren't. Is it a hitchhiker slug your concerned about?

They are hitchhikers. I got a yellow, and two grey slugs. I'm watching them,and so far they are just cruising around on the LR. I saw another one. However, this one looks kind of like a porky pine(sp).
