I tried to post last night, but my phone was being dumb and the app kept crashing on me in the middle of my post.
I am glad that you chose not to go the way of neon tetras- especially since you don't like to see things dead. Neons are pretty, but they are very sensitive!
Have you cycled your 10 gallon already?
Have you thought about trying out gupies? You can do only males or do a trio of one male to two females, but that will result in lots of babies. They are livebearers like molies are. They also come in a variety of colors and are hardy fish. I would suggest that you take a trip to your lfs
and look at the different fish to get an idea of what strikes your fancy. Everyone is different. Just don't come home with any until you've been able to research otherwise you will get upset when you find they are too sensitive or require a bigger tank.
