Tropical fish is really wide scope as compared to goldfish.Some tropical fish such as certain charachins like yellow banded moenkhausias, are rather hardy and so are gouramis like the three-spot gourami so they would require less maintenance as compared to goldfish who give out much more waste.However, then again, other tropical fish like chocolate gouramis are way more vulnerable to infection and need lots of attention, seemingly more than the goldfish who are stringer in their immune system.So it depends on what kinds of tropical fish you are comparing with though I would say most tropical fish are harder to keep due to their sensitivity to Ph and most other stuff (chlorine amount, sand dirt, etc...)
