Coral beauty angelfish

[TS1075]

Can anyone help?
I recently set up and bought fish for my saltwater fish tank. I originally received all the equipment from a friend and set it up about 2 weeks ago. I waited about 1 week and then bought the fish. I used Natures ocean Nutir Seawater. I bought caribsea live sand and a bag of dry caribsea rock. The only fish in there are 3 yellow tailed blue damsels and a Coral beauty. A few days ago I noticed some white coloration on the coral beauties face. I noticed it has worsened over the past few days. Can anyone help me and tell me what I can do to fix this.
Did I get fish too early?
Did I set up the tank wrong?
Could it be related to water conditions?
Any help or advice would be much appreciated considering i am new to the saltwater part of the hobby.

They all eat fine. I have noticed the coral beauty tends to only swim in the back and on the bottom

For some reason I can't see the video, only the preview in what appears to be some marks as if it were some type of injury but I can't say for sure, do you have tests for basic levels such as ammonia, nitrite and nitrates?

Unfortunately I don’t have a saltwater test kit but I do have a freshwater one. Will that work to test it? I will also try to repost the video

Yellow tailed damsels are classed a more aggressive fish, you got 3. Looks like he got fin damage too. Would not surprise me if he's getting bullied.
You haven't mentioned tank size either. How much rock for hiding spots?

Someone who knows a lot about fish diseases will answer I’d you type as I did above. He looks very stressed (your Coral beauty). A lot of the time fish will look like this if they were not acclimated properly. Also, there might be some white spots on him that could be something else.

You need to get a test as soon as possible, I can recommend the Salifert brand. Your tank looks too clean, and probably the water quality is not the best, you added live sand and good quality water but what is biological filtration in the sump? do you have a sump?? How is the tank configured?
As for the coral beauty angel, I think it could be HLLE in my opinion, but those white dots could very well be cryptocarion, in any case whenever I have the opportunity to talk to beginners in the hobby I recommend not adding angels until after 6 months when the tank is a little mature, your tank is too young to house any.

As stated, I think you rushed things a bit. Tank doesn't appear to be cycled and you have some potentially aggressive fish with what looks like very little hiding spaces. I would see if you could pull the angel out and trade back into a LFS?
