Hey people I have this blue leafy algae growing on my live rock. Under white light it appears blue but under my blue light it flouresces orange. What is it?
Difficult to tell With hazy picture. Get a closeup with white lights only. Looks like you have some uncured live rock direct from the sea. Where did it come from to help with identification?
Take a look at this link of red macros in the Gulf if Mexico.

The genus Rhodophyta is the largest and most diverse group of tropical and temperate marine algae with more than 2,000 species worldwide. Their dominant pigment is phycoerythrin, which gives off rich shades of red, orange and blue. Red macro algae are some of the most varied and striking of all marine algae and are highly sought after as aquarium specimens. Identification can be difficult in some species, such as Gracilaria, and some have slight variations depending on the location and depth. Although this index is not a complete listing, it represents species that are commonly available or sought after by marine aquarists. As new species become available to the industry they will be added.
Thanks for your reply. The live rock is from my lfs. It certainly appears to be well matured. Heres some white light only pics. Its the best I can get with my camera.
