Medications and vitamins can be added to a specially prepared mix or what
seems easiest is to let it soak into or paint onto the "bite size pieces"
and then refrozen until feeding time. The later method seems best as it is
much easier to regulate the concentration of the vitamins or medication
keeping to the manufacturers directions avoiding under or overdosing.
Good Luck, Enjoy and Happy Fishkeeping!!!...........
