Just because you have been something for longer, doesn't mean that you have been doing it right for longer.
I know lots of car drivers who have been driving for years and who still drive like they got their licenses out of a wheaties box.
As to answer your question labloverl, common species danios (glofish are modified zebra danios so fall under this banner as well), are much too active for a 10 gallon tank. Generally the recommendation is a 3ft tank as they really require a fair amount of room to swim.
Mollies also grow too big for a 10 gallon tank. However, you could fit in a small school of neons.
There are a lot of fish species outside of the standard neons, guppies, mollies, platys, corydoras, plecos etc. If you are prepared to do your research and set-up your aquarium correctly, there are a lot of nano friendly options that make for a very nice display.
I can make some suggestions, but generally these fish have pretty specific care requirements so I don't want to go suggesting them if you are happier sticking with something like neons.
