Here are actual pics of the growth I am
Looking to identify. Natural sunlight off the sonde. shows it nicely. It is not drowsy due to the sun. Only hits tank for a half hour in mid simmmer. But sure looks nice back to the id. Need some help. See attached.
is it firmly attached to the rock (GHA)? Or does is blow off in sheets (cyano)?
Weird color combos are often some tiny organism growing attached as epiphytes to GHA.
(those are my first thoughts.)
