Advice on a dottyback

Hi I need some advice on my tank and a new addition im looking to add. I have a 4x2x2 reef tank with about 40kg of live rock. I have a sale fin tang, blue tang, 2x clown fish, a pair of coral banded shrimp and a few peppermint's would adding a strawberry dottyback be a good option or would he be to aggressive?? Would he be compatible with the shrimps?
