One of the problems with any treatment that relies on getting the drug into
the affected fish via food is the variability firstly of the concentration
of the drug in the food and then the food into the fish. Sick fish don't
eat as well and may not eat enough to be effective. Also the other side of
the coin - the voracious appetite of the (as yet) unaffected fish may give
him a toxic dose :-(
By using a water soluble drug like Ivermectin I assume the osmoregulation
mechanisms equilibrate the concentrations quickly and effectively for all
inhabitants of the tank and if the concentration is appropriate the
parasite dies and all we have to worry about is the individual
susceptibility of each species to toxicity.
