    The blue Zoanthids and Ricordea don't luminesce when the lights drop to actinic only. At least the ones in my tank don't. It appears that blue corals don't have zooxanthellae. Anyone have information about this?

    Actinics really bring out all colors other then blue, I'm guessing its because the blue light is well, blue.

    Blue corals most definitely do have zooxanthellae; otherwise, they would not be photosynthetic and couldn't survive in a low-nutrient environment.

    Generally, only lighter colors "fluoresce" under actinic lighting; darker colors tend to stay dark.

    Not sure abut all these , today I bought a colony of eagle eyes, at the store where under all led's (blue) , and I could see the blue in the center of the zoas , at home under led's combo 12/k and 453 blue is gone. So I need a only blue light to pop the blue of the corals.

    Fluorescence is due to fluorescent proteins. This has nothing to do with zooxanthellae. Different corals have different fluorescent proteins. Some don't have any. The purpose of fluorescent proteins are not completely known, however, they appear to be involved in protection again free radicals and possibly protection from high energy light.

    I stumbled upon this thread from a while back that has all the resources for anyone wanting more information on this!



    Dingo gives a great overview of the articles listed as well.
