I have decided to stock my 49g tall with zebra danios (top) because of their hardiness and appropriateness for a beginner. Ihave watched them at the LFS and love the schooling darting motion they create. I would like to have serpae tetras for the mid level again for hardiness and I find them very attractive. For the bottom I will have corys and a couple otocinclus.

I have heard the tetras may be a bit aggressive until a shoal has been established. Since I should add only 3 fish per week as I stock the tank, how and when would be the best way to introduce the tetras into this tank?

Thanks in advance for your guidance and expertise.

Becareful with them though, several members have had trouble with them nipping.
I have short finned serpae. From what I understand, the long finned (red minor) have a worse reputation for nipping.
