Im new to saltwater, Is this Ich?

the pet store is pet lovers in abbotsford, the thrashing is not around rocks or anywhere it could be anywhere in the tank, right now i cannot get pictures up. I really hope the fish survives as it is my first larger fish so I would be sad if i lost it. I have not heard anything good about the fish that pet lovers sells, only negative things, so i would not be surprised if the fish does die. I will try to get pictures up asap.

One thing is tho the fish is still eating which makes me happy. All other fish in the aquarium seem very happy as well and eating very well.

And yes that is exactly the stuff. I do not get why you would not dump the stuff right on the fish seems like it would cause way more stress than good.
