I have a res that i got a while back and i decided that i would get another one from the store. i brought it home to a clean tank. when i went to introduce them i set them on the floor and tried to let them meet each other. that didn't work they went opposite ways. so i put them in the tank hoping for the best. well my older one decided to climb on top of the young one then the young one moved out of the way and the older one tried to bite it and continued to do the same thing. i have no idea how to make them live peacefully.
please help
