It does look like ich, however, you called it "bubbles"... Indeed, bubbles can stick to the fish, as can sand grains. Fish also get random white spots (mucus). However, in looking at these fish, I can see some spots on the fins (that rules out mucus). The spots are fairly numerous, on multiple species, so that rules out sand.
You'll need to watch this carefully. If it is ich, the spots will come and go, change in number, but there will be a general trend of the numbers going up over the next few days. Since we are coming up on the holidays, I would strongly urge you to set up a treatment tank now, just in case. To treat this properly, you will need to have the fish in a tank by themselves and treat with either copper or hyposalinity. In some cases, if you have just a few invertebrates, it is easier to just remove them and do hypo right in your display.
