Considered a pest algae in the reef aquarium hobby, and almost impossible to eradicate, I still cannot get over the marvel of its beauty. How can something so beautiful be so unwanted at the same time? Hope you enjoy these.

All were taken with the 40x objective except the first two.

The algae as we see it. This was taken at about 1:2.

10x view of one leaf. The red dots I presume are the chloroplasts fluorescing red under UV excitation due to mainly Chlorophyl a. Chloroplasts are green to the eye due to it absorbing UV, blue and red light but reflecting green.

Cloroplasts with other algae (possibly a diatom) attached to it, and some unknown yellow fluorescing organism.

Chloroplasts and some membrane fluorescing cyan-green.

Chloroplasts in red and other tissue auto fluorescing in green.

A collection of small algae (possibly diatoms) attached to the Bryopsis.

Another diatom attached to the Bryopsis stem.
 
We are spoilt getting to see these, thanks again
