Have a biocube 29 and I also added a 21x1watt led fixture to the stock lighting. My colt sits directly underneath this fixture at the top of my tank. I started to notice the polyps looking like they are in the pics. I can only figure that it might be getting "burned" by the light. What do you think?

I know my colt was happiest in my sandbed. I'd save the top for something that needs the light.

What are we looking at? The polyps that are more swollen than usual or that little area that's shriveled up?
How long has this fixture been over the tank?
How did you acclimate the tank to the new light?

The tips that look like a white clump. Like I took a lighter to the tip like a nylon rope. Acclimated by being on 2hrs the first day and increasing 2hrs every other day until they matched the stock lights. It started looking like this about a week after the new lights, although the colt was in my tank only 2 days before I added the light.

that just happens some times. That's not from a lighting change.
