Just finished my water change with a funny ending. I ended up moving a few things in the tank, including pebbles. One ended up in the stream pile, which became prime real estate (where the flow is at its most powerful). As I put the lid back on, the loaches began swarming the new rock. A scuffle did happen, but didn't last long as the largest easily won. I only caught the end on film, but seeing 5 loaches swarm this rather small rock made me laugh.
