Is my Zoa bleaching?

[Ocean’s Piece]

This is what it looked like when I got it a week and a half ago

This is what it looks like today

Some of the polyps are looking not as vibrant and don’t have all their color. I have noticed that there have been quite a few more polyps that have been growing but I found it strange when I saw some existing polyps not looking as vibrant. Could it be bleaching? Could it be the algae I couldn’t remove that is still on top of some polyps? Could it be the dip that I did? What do you think?

Could it also be due to the fact that I have a little bit of temperature fluctuations every now and then going anywhere from 78-80? Could me not feeding them be an issue? I know they rely mostly on light so I haven’t fed anything and the only food source they get it stuff in the water column. Could it be my lights? They’re the Biocube stock lights. They may be too strong. What do y’all think it could be?

Zoas are pretty hardy, not lights or temp.
Any critters that might take a nibble?

Only fish I have in there is a royal gramma. I haven’t seen him do much to them. Only thing he does is look at that rock and sometimes nips on the rock nearby but I think those may be copepods or some small microorganisms he’s nipping at.

No crabs?

No crabs?

Trochus and Astrea Snails only. I don’t know if it’s because the fish store has different lights and it’s responding differently to my lights or something else. All my other corals vibrancy look fine though.
