I am wanting to put neon tetras in my 55 gallon tank. I had one in there for a long time by itself then i bought 3 for 99 cents a piece at my lfs. within a week they all four died! It did not hurt any of my other fish thank goodness. I went to another lfs to check into buting some more. I ask them how many they reccomended i get at a time to keep them all healthy. They said the more the better and i should start out with no less than six at once. What do you guys think about that? It would cost me about 15$ to get that many at once. Would it be worth it? Or can i start out with three and get some more a coulple of weeks later. I need some advice on this one please help.
