A word of warning on being able to quickly order and receive fish and bird antibiotics. I tried to order a resupply during the pandemic 3 years ago, and everywhere I tried was out of stock. (Fish antibiotics.) I'm pretty sure that was because preppers were stocking up for themselves. This time around, the same thing could happen because people will be buying fish and bird antibiotics since most livestock antibiotics will no longer be able without a vet prescription. I ordered and received a resupply last week just to make sure I have them on hand.
