Black Moor fish with white spots?! HELP!?

I bought a Black Moor fish about a week and a half ago. They told me it was okay to put him in a bowl. So I bought a fish bowl, and some of those colorful rocks to put in the bottom. I cleaned his tank yesterday but when I filled it back up with tap water and put some of that AquaSafe stuff in it, the water was still foggy. I thought maybe it was a film coming from the rocks. But about three days ago I noticed that my fish has white spots on his body, and there seems to be more now. Today I noticed a giant white spot above his eye, but its gone now. I looked online and it said that he probaby had “Ich”? I dont know what to do to fix this. My mom had a fish and she used to use distilled water and that seemed to help the fogginess. I just need to know what to do, about the foggy water AND MORE IMPORTANTLY, the white spots. I’d be absolutey devastated if I lost this fish. Help please? Thanks so much.
Also, my fish keeps coming up for air every five seconds, like he’s sucking the air. And there are bubbles lining the top of the water. What is that?
