My hillstream loach is ādefendingā my snail from the cories and yo-yo loaches, and it is so interesting in that itās like they are now friends with each other. My Hillstream doesnāt like cories, so she chases them a bit, but they donāt get hurt, and she tries to back off the loaches from the snail. Itās an interesting behavior seen in them, but I think itās also just a coincidence.
