Just saw this guy on the glass. What is it and is it good, bad, or ugly??? Thanks.

Looks like a flat worm, not sure of the species.

+1 for flatworm. Many (most?) are harmless but can quickly reproduce to plague proportions. If you can catch the issue early enough, a simple siphon made from a length of silicon airline tubing attached to a piece of rigid airline tubing will allow you to stay on top of them.

Happy Hunting!

Predatory Polyclad flatworm. Rhabdocoela sp. I'd just siphon them out as billdogg said. I've heard the white ones can have a taste for coral.

Clear ones or white ones are okay imo.
Red ones are not.

Thanks. I just scraped it off the glass and used a net to remove it. It will be interesting to see if/when I see any others.
