New acan dying

[gh_reefer]

Hi, I got a new acan last night and was healty when I pick it up from the store. I got acclimated it and got it into the tank as well as my blasto and Duncan they are doing great so far as well as my Clownfish they are all eating great! But my scan got half bleached as you can see in the pictures. Please help me I put them in direct blue light I think that is when I went wrong. But it was late and onky had the light on for 2 hours then turned them off and went to bed. If I what the problem is. All tank parameters are good. I put it in some shade to let it recoop and am direct feeding. Please tell me if the light was the problem.

Looks like your shrimp is/was pecking/eating it.

Peppermint Shrimps love Acans. Unfortunately, yours has a taste for corals. They can quickly destroy a coral overnight. You might want to remove the shrimp.
