Fan Worm Coloring

[DLHDesign]

Saw this today and thought it was pretty cool. Grabbed a video for kicks:


Anyone know why this is happening?

(Video quality isn't as high as hoped; the fan is going from having a greenish tinge to white and back, alternating on each side.)

All that type of duster do it but its unknown why...but the only way to see that is if your lighting is on the 10k side. When I first started I ran my first tank with the supplied lights. After I upgraded to better lights I could no longer see it.

Good to know, but also very frustrating... :-(

The lights over this tank (a "temporary" coral QT) is an old CoralVue rig that someone gave me; I suspect it's in the 10k range, so that makes sense.

I have about 6 tiny ones in my tank. I hope they grow larger and reproduce! Love the look! Awesome video!! The green is nice!
