Ok sorry for the confusion; I'll try again.
I live in Europe and I have no easy access to USA medicines to treat my fish. In Europe treatments for fish are very mild and they do not really have strong components. It's more natural extracts.
I don't have a quarantine tank, so all I can do is dose in my main display tank where I have fish, inverts, corals and anemone.
I was thinking to make a one-time purchase directly from USA even if it's really expensive with shipping cost, to get the "must have in-house medicines". I was asking if you could provide me a list of medicines I must have at home to treat and cover the most basic issues with fish such as bacterial infections, parasites, ich, gill flukes, velvet keeping in mind I can only dose in my DT.
For example:
Ruby Rally PRO, PraziPro, Coppersafe Fritz, Hydroplex, Ich-x etc...
