I have had an idea swirling in my mind for a couple of days now, i bought an antifungal and an antibiotic to counter ich, popeye, etc. (fortunately my betta is healthy and in no need of them)
So i was thinking if it would be recommendable to place a couple of drops after a water change, sort of like a vaccination, or would it be counterproductive to the health of the fish to do it, and only use the products in case of the fish being ill?
What are your thoughts/experience on the matter?
Thanks for your help and insight
