I'm starting to stock a 29g tall and I want to start with some Danios (mainly because my son has fallen in love with the geneticly altered 'GloFish' Danio).

Because I know these are schooling fish and are happier and healthier in a schoal I want to get several. Do I need to get all the same type for a schoal? I was hoping for a couple of Glo's, a couple of longfin Zebra's, maybe a couple of longfin Golden. Would these school together or do I need to get more of each type to lower stress to the fish?

As a child I remember my mother had two Zebra's that chased each other all over the tank. I thought it was because they were happy and playful but now I realize it was perhaps stress and agression. I really don't want unhappy fishies

Probably better off with a few of each imo.

 

[Cariessa]

Can you define 'a few'? Would three of each be enough or are we talking five or six?

The glos are geneticly altered zebras.
They will school with the regular zebras.
In the wild many species of danio school together.

I know that Danios will shool together. I've heard to keep sets of at least three. I usually go with pairs. If you get a chance, look for leopard danios. They are a variation of the zebra, but instead they are spotted with a yellow body. I think that I still have two that are about a year and a half old. I find them more hardy than the zebras in my opinion.
