Black String/Worm Like things in QT

[Falco]

Hi all,

I currently have a pair of clowns in a 20g long QT that have been in for about 2 1/2 weeks now. They look great, are eating well and everything seems to be ok. The only thing I have noticed are these black string like "worms" all over the QT, which I don't think are actually alive because the ones in the low flow areas are not "moving". Any ideas?

Looks like algae growth to me.
