I have my 20 gallon tank with 3 white clouds and 3 zebra danios.(i know its not enough for a proper school but i was told they would school together by the lfs). anyway 2 have died so i now have 2 of each.

Now one of the danios is bullying the rest of the fish. is this just cause a lack of numbers of the fish? and what should i do. It seems as though the bully is herding them to one side of the tank. and if they move she chases them back over.
 
when they aren't in a big enough school, they tend to be more aggressive so you are right. what i would do is to get at least 6 of each species and they will most likely calm down.
 
Alright thank you

also is there anyway to know how old a fish is that you get from the lfs? or just have to guess based on size?
