The schooling fish I have are corys and white cloud tetras. I have 4 of each. Both only swim in schools of 3 almost all of the time there is almost always an outcast. Is there any reason for this?
is 4 a bad number?

I suppose if you are Japanese where death and 4 are the same or similar (dont' remember which) then it is a bad number. But I can't explain why your fish are doing that/.
even number of fish is always bad luck for me one or the other always dies. Thats why i always keep odd numbers, i need to get another bamboo shrimp =p
IME schooling fish will sometimes break into smaller groups and then join back into one large school again. I've noticed it several times in my own tanks, but it doesn't happen a lot. Except for a couple of rare exceptions, all my schools have 7 or more fish of the same specie.
Four fish is, IMO, not a school. You really need to have at least six for a school and more than that is better. IME that's why one of your fish ends up alone. When my schools break up there are never any fish left alone. They always break up in groups of three or more and there are never any pairs, always three is the smallest group.
Once in a while a fish finds himself alone, but you can see by his attitude that it's a mistake. He looks for his buddies ASAP and joins up with them.
