Would perform water change ,day before adding the fish ,so that water change day does not fall during time fish are acclimating to new surrounding's/water chemistry.
I don't think a dozen Serpae/ Pristella would be too much of a load with the cory's if regular maint routine is observed.At the very least,,eight would be my aim.
Plant's would be a plus.

Yeah, the tank is fairly well planted - you can see the photos in the Aquariums tab. I do 50% WC weekly. Before the water change today, I checked the nitrate values and I was sitting somewhere between 0 and the first measurable level, 10 ppm, so I estimate about 5 ppm.

Also, regarding whether I want more or less colour...

Some colour and contrast is of course welcome, since the peppered Cories aren't exactly the most colourful of fish (in terms of appearance. Doesn't speak for their character ;) ). However, I put "peaceful" in the thread title here because that's precisely what I'd prefer. If the Serpae tetras are not going to go after the Cory cats at all, I do admit that they look pretty awesome in their blood-red colouring and I was rather taken by them the last time I was at the LFS. I was just concerned since the Cories do come out of the substrate-area and do some venturing into the upper areas of the water column.

But yeah, a peaceful, good-natured tank is actually more important to me than putting on a big visual spectacle.

Serpae's should pose no risk at all to the cory's, Will confine their attention's amongst themselves.
Can be nippy with each other but once pecking order is established, and number's are not too few,then they settle down.
Newcomer's will be tested, but they too will fall into the order and less friction will be observed as they grow accustomed to new tank and tankmates.

Yes ,I agree Byron .
After viewing OP's tank,, I would consider plant mass is enough to introduce them all at once.
Problem for me,, is often what some folks describe as heavily planted,or well planted, is their opinion and without a photo,,I alway's try to err on the side of caution.
Takes a fair amount of plant's in my view ,to consume the ammonia from a group of fish introduced all at one go, but it can be done with enough plant's that are thriving and not dying.(would still monitor the water).

Great, I'll plan a visit to the LFS.

On a side note, I was at a big chain store to just pick up some filter material - in Germany many big Home Depot type places also have a large pet section with a large selection of fish. Anyway, they had some Serpae's in stock and they looked awful, really faded colour and the fins didn't look in great shape. In comparison, the little local shop that I've been going to had a tank that as I mentioned with Serpaes that had a beautiful deep red colour that took my breath away. Needless to say, I know where I will go when buying more fish...

So, I added 12 Serpae tetras yesterday. They are a very beautiful fish, but I'm already concerned about their aggressivity. The whole day yesterday, they didn't seem to bother the cories at all, but this morning I saw not only males (I presume) sparring among themselves, I saw one of the little guys try to take a nibble at one of the cories. The cory was quick enough to get away, and who's to say he'll manage to not get nipped next time? So my feelings are mixed at the moment. Will floating plants make a difference to their behaviour? I've ordered some water sprite already in the hopes that it might calm their nerves and be more peaceful.

Floating cover makes most fishes feel more easy,but also blocks light to plant's below if close attention and periodic removal is not performed.
I pull gob's of pennywort from the surface to prevent it from blocking light/growth to plant's below.
Still think the cory's will be fine after some time, assuming they can utilize the wood you
have for resting area's out of the way of boistorous Serpae's.
Most fish(not all), don't like picking/poking at fish that can poke back, such as catfish with their spiny dorsal,pectoral fins.
Fish have only been in the tank since yesterday,,would not worry yet about thing's while fishes are acclimating and developing pecking order.
Keep the water clean, and maybe test for ammonia for a couple day's to ensure that biological filter is keeping up with recent addition of fishes.

Agree. Wouldn't worry too much, your tetra are exploring their environment, and the cories are part of their environment. There's enough tetras that they'll amuse each other later on and probably forget the cories are there completely- especially if they get poked by some spines.
