Added a frag a few weeks ago to my tank and over the last couple weeks I've noticed this white edge which has also curled up a bit. Is this cap bleeching?
I'm going with growth as well, I believe the pic makes it look like it's bleaching. If it wasn't there before, the cupping on the edges are a sign of growth.
Does that cupping eventually plane out or are they reaching for more light? I have a green monti cap and I know its growth as new polyps are on the curked edges but wasnt sure if maybe I should lift it up higher? It's about 6 inches from my sb almost directly under the center of the light. 29 biocube rebuilt with AI prime HD. Light is about 10 inches above water
