Sorry, but an uncycled 5 gal is not a good option for a coral. You will be struggling to keep water conditions decent. I suggest you do a 1/2 gal to 1 gal water change daily. Maybe you can use some fake coral.
I'm hoping you'll start to see improvement within 2 days.
What remains is figuring out who is to blame for the aggression.
