Is this bleaching?

[Protodad]

New to SPS. I believe these are montipora or psammocora. They were reasonably bright when put in but immediately started to show patches of white. I run 4 a360s on a 120g so I have them placed near the bottom of the tank currently. Is this too much/too little light or something else entirely? I’ve never tried sps outside of a small digitada frag 6 months ago I lost when I had copper leech into the tank.

Day they were put in

3 days later

They look to be dieing, but they also look like they had fish bites on the first day. I had a blenny that nibbled on sps and left similar half moon bite marks.

I just pulled a damsel out that was picking at my acan frag. It’s probably that.

May be High alk and/or low calcium

Medium flow and moderate light, Assure Phosphate not elevated and look under frag plug and assure no bugs or pests.
This is mine which started as a frag like yours:

Now that I think about it, the diamond goby sits right near where they are acclimating. I know he moves stuff around and I’ve found them knocked out of their holder.
