Hello all, in my tank, my ornate bichir lives a usually very peaceful lifestyle, him and the red tiger each control one side of the tank. However, whenever the bichir travels to the other side, the red tiger hits him a little, not a bloodbath or brawl, just a poke or two, depending on if he stays. I'm worried that the red tiger will eventually try and kill the bichir. They're both around 4 inches long. Do I have anything to worry about?
