I dealt with it for my puffer. In az though. My puffer had the same thing. Your fish will survive until it comes. Mine did for the three plus weeks it took me to figure out levamisole was the answer. Key is dose it for 24hours once a week for 4 weeks. It only works on young and old worms. Not on eggs or larvae. Thats y you dose for 4 weeks, to hit it at all cycles in case it laid eggs.
