For those who put these away in your preps, here are some emails I have recently received from my “fish” site. The first one said there would be a shortage of fish antibiotics as they would be unable to get new items from their supplier.
Then got an email saying Midland Vet has stopped manufacturing fish antibiotics. Midland I think is the one who makes the Aqua brand.
In the news (Dec 14th), the FDA is going after 9 suppliers of fish antibiotics who must stop manufacturing or face legal action.
So the way I see and understand this, there will be no more manufactured for fish, birds etc that can be sold OTC. You may want to stock up a bit if you need these for your sick fish.
