ID yellow stuff and Copepod?

Copepods are absolutely smaller, tiny little dots. Here's one from my Pod section:

I also see a flatworm in the 4th shot upper right corner. I can't tell if its a planara or not though. Marc, what do you think?
 
If they are clear or whitish, they are benign and nothing to worry about. If they are rust colored, you'll want to siphon them out. Here's more about them.
