A while ago I posted a video of these loaches doing a bit of fighting over the pecking order. The video was awful, and in the meantime I have figured out how to use my camera a bit better. So I caught them at it more recently and got a much better video of them (click to view video):
This time they were going at it for quite a while, about an hour off and on. No damage done, fortunately. I'm planning to up the shoal to six loaches and swap out my cories, so I hope that will maybe spread any aggression out more evenly. Also will be adding more driftwood, their preferred hiding area. Hope you liked this little glimpse of loach drama!
