is it a slug?

[Joe V.]

When I turned my lights on tonight, I noticed there were many slug-like
critters on the glass. I tried taking a picture, but it didn't come out well
....

They were <1mm in length, transparent with a black dot-like thing inside
their bodies. The body was bullet shaped, but the tail had two appendiges
that kidna formed a crescent (like an ear-wig, but not so big when compared
to the body).

They moved pretty fast, and didn't seem to like the light all that much.

I have Nassarius snails, Turbo snails and what I think are baby cerith
snails (cone-shaped shells, a little pinkish) that came with some of the
live rock.

Any ideas?

Thanks!

You didn't mention the color, but that sounds like one type of flatworm. Unless
they are rust color, typically they aren't a problem at all.

These were transparent ... kinda whitish in the middle.

You had issues with flatworms, right? Are they of any good to the tank? I'm
wondering if I should start picking them off right now ... ?

You had an problem with flatworms in the new tank, right?

Whitish flatworms are benign. The only bad ones by reputation are Red Planaria,
as they create a mat and smother the DSB and possibly some corals. They can get
out of proportion quickly in some systems, and if they die all at once (called
'crashing') the ammonia level spikes very high, causing the domino effect of
death of most if not all livestock (according to reports on RC).

I've had the whitish ones in my refugium, took a few pictures and enjoyed their
motility, but they are nothing to worry about.

Go to this page and down to the flatworm section. It has a very good
picture of the two prong flat worms that I think you are describing.

Your description rang a bell with me as I just saw these little guys
in my refugium the other night. How odd.
