Personally I wouldn't put anything from the pond into the tank. A great way to add parasites and potential disease. If it was me I'd use either fish feed or ammonia to feed the bacteria until the tank cycles. Then just before adding the fish they would get a salt dip to rid them of any ectoparasites. That is what I did and knock on wood I have no problems with parasites or disease.
If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
