On here people think a 10 gallon is huge, but they still limit you a whole lot when it comes to stocking. Really just one big school of fish is best. So if you do neons do like 9, cherry barbs like 7 and so fourth.
You won't be able to do two schools besides bare minimum, and fish don't do good if you do something minimal. So it is better for you to stick with one species.
