As much as I said not to add more, I do still agree with this. Neons don't do well in a small tank unless its a species only and enough of the neons are together. In a group of less than 10, they tend to die off one at a time, and usually for no apparent reason. With their schooling instincts, they stress more if there aren't enough. Stress weakens the immune system. Weaker fish without proper conditions (their large group) don't have much of a chance.
However, I won't say its impossible to raise neons in small groups, because I've done it. I had 1 neon that lived with my guppies and mollys for 5 yrs. He was the only neon. The average life span of a healthy neon is about 4 yrs. Time, attention to needs and details, and patience can go a long way.
