Acro tips fluorescing after switching lighting

[Boxofpurplerocks]

Recently (~1 month ago) switched the lighting on my tank from black box leds to a six bulb sun power t5 (hung ~6 inches over an 18” deep tank) with a reef brite XHO actinic blue strip as well. Within the past week, I’ve seen one of my acros (the highest one in the tank, maybe 8” from the surface), develop yellow flourescing tips. I’ve had this acro for over a year, plus I’ve seen pictures of the other frags, so I know this is not natural coloration. Is this a reaction to the light? Anyone experience something similar before?

Sorry for the all blue pics, took this just now when only the Reef Brites were on which is when these are most noticeable.

It's pretty common to see color changes when you switch lighting. Especially better lighting like you've done.
