Same species (well, sometimes - a lot of albinos are paleatus and they can be other species) but not same look. Schooling is visual - they won't school for the same reason Neons (two glowing stripes) and Black Neons (two glowing stripes) won't - very different looking fish. Pick the one you like, the fish will be better off and it'll be a nicer visual statement anyway.

As mentioned above, they school by appearence and you would have two groups in your tank. Neither group would be very happy as they shoal together and numbers ideally should be atlest 5/6.

My 6 Albino Corydoras are always schooling on their own, while the Bronze Corydoras & the Agassizii stick together.

I must just have odd cories- my albinos and bronzes school together. I have 3 of each and they're always playing and swimming except at feeding time when it's every fish for him/herself.

I also have 2 of each in a 10 gallon tank, and they stick together most of the time.

I agree, my bronze and albinos, 3 bronze 2 albinos, also school together, and are constantly cuddling and breeding with each other. My aggassiz however are loners and dont school with either.
Also, my neons school with my glowlights and my leopard danios as well as my white clouds, its just one big motley school of fish 98% of the time.
The penguin tetras only school with each other though.

I have four trilineatus and one agassizzi and they all school together. I started out with two trilines and the agassizzi and am still waiting for more of the agassizzis to come in (they're on order).

Actually, more often than not, I'll see four cories together and one apart from the others... and the loner is NOT the agassizzi.

And now I will stop typing agassizzi cause it's just too bloody hard to type quickly.

~Meow. Thus spoke the cat.~

In each of the cases above, though, there are too few of each type to be a school. Watch a tank with large groups of two species and it's a very different story. My 12+ Aeneas will have nothing to do with the 8+ Arcuatus - but when I had two of each? Yeah, they stayed together, but it was out of the fear a schooling fish feels when he's very nearly alone.

I have 6 bronze cories and 4 albino cories and they all hang out together. Judging by the number of eggs on the glass, they get along quite well

But I am going to get more albinos so I can have a proper sized group. They're the coolest fish ever

Mmm, yes, I agree LittleMousling. On the other hand, I feel much better knowing that *I* have the agassizzi, rather than leaving him all alone at the LFS (he was by himself in a tank of some fast moving schoolers or another). And considering how long it's taking to get some friends for him, I'm glad I have him and that he likes his triline buddies. Besides, he's adorable.

Of course, getting him threw off the balance of everything. I don't have enough room for two proper schools of cories in my twenty gallon, so instead of the school of eight that I was planning on, I intend to have two mini schools of four. *shrugs* When I move out and can get a bigger tank, I'll be sure to have even more cories.

As for the issue of the albino/bronze cories, personally I'd say that it would look more "together" if you had just one color morph. My trilines look similar to my agassizzi so my tank doesn't look terribly mismatched.

I think however that Cory Addict said that Corys are not really "Schooling" Fish at all. I remember she said that in the wild corys only loosely associate and thats probably only for breeding I would think. Corys are a shoaling fish - if there are many in a small space they will shoal together. But they are NOT a schooling fish as has been said before.
I often wonder if putting so many corys in one small space together is perhaps more stressful on them than if we only put a few in a larger space which would be much more like nature.

I just looked up "school" on two online dictionaries. They both said a school was a group of fish, of the same kind, swimming together in a group.

After seeing a group of 10 or more cories swimming side-by-side around a huge display tank at ThatFishPlace's store, I'd say they ARE schooling fish.

Cories shoal in the wild-they may not stay in tightly formed groups swimming in unison, but they do shoal-staying together in numbers.
