Not just the boat, but the entire armada(fleet of boats)
One, there is no reason to treat this animal for parasites. It does not exhibit any symtoms of a parasite overload.
Two, before you treat something, it should be determined it needs treatment.
Three, if a Vet sees the animals and recomends a partcular treatment. You offered a bunch, all for different types of parasites and infections, which one should they use????????
Four, Do not give medical advice your not qualified to give. I am positive the vets you work for, will tell you the same.
As a keeper with lots of experience with both captive and wild caught monitors. I have seen far more damage for the treatments of parasites, then from the parasites themselves.
To make that clear, I have nothing against qualified personal treating monitors for parasites. But I have a lot against the casual keeper/shopkeeper/importer, doing this treatment.
Its my bet, the damage is from poor treatment(if a little is good, more is better) and or, the muliple treatments. That is, wildcaught monitors are oftened treated many times before the consumer gets them. They may be treated by the exporter, then the importer, then the jobber, then a shop, the by the keeper. Sir, those animals are toast.
The problem is, private folks do not provide a medical record. Vets do. Vets keep these records because they are important for any further treatment of an individual. In many cases, the above double or triple the treatments.
So yes, I do not think you should be offering treatments(you indeed offered the dosages) If you HAD A BRAIN, you would know better. Well you have a brain, use it. Its simply not a wise practice to treat animals for things they do not need.
Cheers and more cheers
