Quarantine tank and medications for new fish

[TrueNorth]

Hello everyone
I am getting back into the hobby after a break.
My plan is to order some fish from different sources and putting them through quarantine first before they go together in one tank.

My question is what kind of meds do you guys put into the quarantine tank to tread them for all kinds, as a precaution. (Internal and external diseases)
Since Canada has banned many aquaristic medications, what do you use and where can I get it?

Thank you for your help

Hi,

They are striped hypancistrus.
Nobody knows better than the catcher what they are really for.
The question is not whether it really is Hypancistrus sp. "L236", but whether you trust the current owner.

Cheers
