Why are Fish antibiotics getting scace?

[putnam6]

Hey mate,
Do you have a large aquarium?
If you don't, I am sure you are aware you can get the same immune boosting if you really need it, from daily quercetin with zinc. 
And the best immune booster is daily exercise, even just a walk for an hour a day and some sunshine.
Just normal natural stuff...
Best to you :)

Yes, we do...occasionally our fish get a bad toothache 

I do take zinc actually, 30mgs most days unless I forget, along with the oregano/black seed oil, garlic, honey, vitamin C, magnesium, etc, for an immunity boost, pretty much since COVID.
