Be sure to do water changes as the bio-filtration might not be built up yet since you just filed the tanks. The nitrates/nitrites could spike and poison them. Using pond water might help jump start that as it probably had some beneficial bacteria in it but usually you want to age a filtration system a little before loading it with fish. Especially if you are feeding a lot.
I think Ken knows about that. He's been there done that right Ken?
