Thanks . . . 
One thing to note . . . these guys must just THRIVE in the wild . . . When I bought these guys, I did the catching myself. There were like 40 of them in a 50 gallon tank. I have to say it is SUPER hard to try to catch any individual cory. When they all zip together, and with that stripy pattern, it seems almost impossible to lock on to one individual fish, even though they all have slightly different pattern. It's like the zebra effect. In huge schools, they must be difficult fish to prey on.
Must be why so many cories have spotted/stripy pattern.
