I'll agred with Vicky here. IF the little guy is eating and
drinking, pooping, active and growing like a healthy little dragon should be, then there is no need to give him Reptaid. But two things I want to mention here. First is that he came from the store whose reptutation with reptiles is not the best. And it is likely that he came with parasites. So keep that in mind and watch him for changes or any decline. Second is that Reptaid is NOT medecine. Not even close. It is only herbs. So lets not keep talking about it like we are giving our reptiles medecine when we give them reptaid.
There are a lot of people who treat their animals when they get them, as part of their quarantine proceedure. You never bring a new animal into the area of the rest of your colony until you are sure that you are not introducing some contamination or disease. In the past a conscientious breeder who obtained a new reptile would take it to the vet, get a fecal check done as part of an overall checkup and then treat the animal if needed for whatever might be ailing it. Well, we are breeders and for over a year now when we get a new adult wildcaught animal or a rescue animal, we automatically put them on Reptaid. All of them. No exceptions. That is for adult animals. All wild caught animals bring things with them from the wild. So we treat them all.
But you don't need to treat a baby if there is nothing apparantly wrong with it. Parasites are not passed to the eggs so even if the parents had a bad case of parasites, the eggs should be clean. The baby gets a fresh start at life and should be healthy if feed and housed correctly.
So the long and short of this is, if a baby is healthy, it should not need Reptaid.
If you get an adult animal, Reptaid is a good part of the quarantine process.
