Diamond Tetra School
 
Quick Question...

What should be the common ration of males to females in a Diamond Tetra School and why?

I guess it doen't matter unless you are trying to breed them, 2 males for a girl so all the eggs are fertilized.
Just my option :-D

It doesn't seem to matter too much, this in my experience is not a tetra where the males relentlessly drive females, so something around an equal mix of male/female is fine.

I'm not necessarily trying to breed them. I am merely trying to keep the peace in the community tank. I didn't want to get nothing but flashy males and have them fighting each other all the time and causing unnecessary stress...

Generally, for species such as this, a mix of male/female is always best. Male characins will often exhibit behaviours and colouring when females are present, and observing natural behaviours is one of the great joys of keeping fish. The exact ratio as I said previously doesn't seem to matter much, but I would try to get it fairly close for the best from the fish.

I agree, I have 10 and they spawn quite regularly. I believe I have 6 males and 4 females, and the males do flare at each other while attempting to drive the females into the plants. They mostly don't get violent though, mostly just shows, but I have seen a male look a bit rough on the fins from time to time. It would be better I think if it was 5/5 or possible 4/6 with there being more females than males. They'll form a pecking order of sorts, I have one male that very much acts like the king of the tank.

Still though, my fish appear to be happy, and I have one little fry that managed to make it against the odds and is about 1/2" in size now.

Seing the males flare at each other though is quite fun to watch, as that is when you'll see the males with their fins fully extended and looking their best. Then see them get shot down by the females when they are not ready to spawn.

No bullying by Diamond Tetras
 
I haven't had the experience with these that Geomancer describes, but I had 8 of them for quite some time, and in my experience at least they didn't bully each other. I love them - so sparkly - and I don't tolerate any bullying in my tanks (makes me nervous), so these were a good fit for me.

I tend to agree with Geomancer.
I personaly tend to go for more females, as this stops the males fighting to mate.
Once the fish are established in the tank they do find a pecking order and settle down relatively quickly and any fighting to achieve a pecking order soon stops.
Male Diamond Tetra's do flare at each other, but this does not stress them undully, it is all part of the mating rituals that these fascinating fish show.
Enjoy your diamonds

Thanks to everyone for all the great tips! I can't wait to get my new 55 Gallon next week. I think waiting through the cycle period will be the longest time ever.
