Neons are... Well... Tricky. Keeping them healthy is a trick. For me they only last about 6month to a year. That's with regular water changes as well. With my cousin who I have my neons too. They are still alive and thriving. That's with one water change a year sadly. The odds are getting worse of having a good batch as most come from big box stores or irresponsible breeders out in Asia somewhere. Your best bet would to go with nice big tank and ALOT of plants.
