I’ve had this JF grafted rainbow monti growing out nicely on the bottom. I slowly lost the rainbows in the polyps and mostly turning green. I know I’m due to update a few T-5 lights, could lighting be an issue? I don’t have parameters but the rest of the tank and colors on my sps are vibrant and look the way they should. This is the only coral changing color.

Happened to me as well when it started getting big. This is mine, you can see it here.

Not sure why it happens but I’m curious too so following along

Only new growth will have the different colored polyps.

Nothing is wrong

But the green polyps use to have yellow centers too? @WWC does this look like your coloney?

With all of the "rainbow" encrusting montis, only the leading edge will have the rainbow of colors... the older parts will usually have monochromatic polyps and a different color monochromatic and base.

Thank you, that’s too bad but still a super bright piece.

That's why frags look so colorful, growth in every direction.
