Nah, you won't get it. They attach to fish, the little 'cysts' fall off down into the gravel and hatch. Within 3 days they've attached to fish in different places or other fish in the tank. Won't hurt you a bit though. If you've got more than one tank don't use nets or decorations from the ich tank to the other tank without sterilizing. In your case you've got tough fish, I'd run to PetsMart and get some RidIch+ (remember the plus sign lol) and use that according to directions. I normally use salt and heat to treat it with scaleless fish but there's no real need for you to do that.
