Need help identifying- is this ick?

[DElle]

1. Can anyone identify what this white spot is? 

I’ve had this fish nearly 3 weeks purchased from a private breeder. I isolated it in a separate tank from my other fish, treated with salt first which made it much more pronounced. I added the salt upon seeing this fish swimming upside down and acting odd (which has since stopped). I have some ick X and was going to add that too, but I don’t know if you can have both ick X and salt together. 

2. can ick X be used simultaneously with salt?

3. Is this a female fish or a male? I’m thinking it’s a female.

I really want to save this fish!! 

thanks!!

Thank you for taking the time to reply. I didn’t think it looked like ick but wasn’t sure.
