While I'm sure this is no dramatic scientific discovery, I'm curious to see how many others have observed this behavior:
One of my emerald cories apparently got tired of waiting for flakes to fall to the substrate. It has figured out how to swim upside-down at the water surface to grab up the flakes. Also, about a week after I started feeding tubifex cubes (by sticking them to the tank wall), it figured out how to swim up and grab mouthfuls.
I've never noticed the other two cories doing anything like this. They're content to stay at the bottom, only sometimes darting up for gulps of air. Is it possible that this might be a learned behavior and that the others will soon follow its example?
I just found this to be an odd and quirky behavior. How many of you cory keepers have seen this? Did only one of your cories do it, or did your others soon figure out how?
