A wide array of people-safe antibiotics packaged for your garden pond or aquarium. Prices are decent for what you are getting, and no prescriptions are required.

Azithromycin, however, is on the way out as far as availability, and definitely worth having if pneumonia and other respiratory infections are a concern. They still have the 30-count bottle in stock, which is 5 courses. You can even find the expiration date listed for each product as of their last delivery of product.
