Possible Ich

[Jpower]

So basically picked up 2 Snowflake Clownfish in Calgary! I am super excited to have my first fish, unfortunatly I think they have Ich. Basically put them in my JBJ quarantine cube filled with water out of my Display Tank. One of the clowfish has a small pin sized hole in the top fin and then what looks like 1 grain of salt on its back fin. Unsure if this is ich or not but better safe then sorry.

Was planning on getting a med with copper and a test kit. Is this the easiest way to go?
