Hey guys . I know this is a very old Post. I have a male and female in a 125. No real aggression,but they stay mostly away from each other unless it's feeding time. They do occasionally test each other ,doing a lip lock. My femalis bigger then the male so that's probably good. Hopefully they spawn sometime but never spend any time near each other. Is this normal and does it sometimes change. They have been in the tank a few weeks. Thanks.. crash.. .I think I have a video I will post.
