You DID ask how to stop your fish from smelling bad, so the tanks do smell, too.
There should be no smell, if kept clean. Some reptiles will poop/pee, when threatened, which smells, which is its natural defense, and not related to proper husbandry.
You would serve yourself much better if you stopped debating this, and started making sure your animals stop smelling, and they'll be healthier, too. Good luck.
If you think an iguana smells, it's only because that animal has not been properly cared for, either.
