New Fox Coral not doing great. Water change?

[LeanneP]

I purchased a fox coral and bubble coral 4 days ago. Bubble is looking good but the Fox coral is still not opening very much and looks like it is struggling. I have it in low flow, close to the bubble and have been covering with screens to cut down on the halide lighting. I am going to be quite busy and away the next couple of weeks so I am wondering if it is good to do a water change today since it will be at least two weeks before I do another or will this just stress the fox coral more. I know they don't like really clean water so not sure which is better. I usually do W/C every week and a half or so. All my other corals look fine.
