Hi, I am currently in the possession of two beautiful tiger oscars that have been growing up together. Someone had them in a 90 with smaller fish and they were eating them and then they were temporarily in a 20 gallon and some larger convicts were picking on them. Their owner was going to take one back to the LFS but when I told her I was interested in them she brought them for a two hour drive to my home. The pail got dumped over in her car and the water had to be replaced. After all they have been through they are now safe in my 55 gallon temporarily until I can get a larger tank set up for them. These fish swim side by side rubbing up against each other at times. They will lay practicly on top of each other on the bottom of tank. There has been some lip locking but it doesn't really seem like aggression. Also sometimes one of them shimmies his tail a bit. They seem like they are in love. What do you think? Could this possibly be a mating ritual. Not sure if it's ok to post a video here but here they are their first day in their new tank.
