They're active, yes...but they don't need to have "new" areas to explore all the time. Fish psychology isn't complex enough to cause boredom with monotony.
Think of it this way - when you go for a walk would it matter to your body if it around a room, or on a long flat paved trail so long as you walked the same speed for the same amount of time? Only in your mind would it matter as you'd be bored with the room.
As long as the cory has enough room to move, they probably don't give the slightest bit whether or not the scenery repeats itself as they swim the perimeter of the tank. They just need to be able to swim, forage, and have places to rest away from the other fish and out of the light.
A 10g with a betta gives them more than ample accommodations if you ask me. Naturally I'm not a cory so I can't answer you factually - but I would think it a hard press to find corys who would be notably unhappy in a well kept tank of ten gallons.
