the oscar ignores everything because ther is no one that will be able to stand up to him for a long time..... the gt is aggressive but nothing besidees the usual display of dominance just a little chase here and there but never got to rough.... im still nto sure what could have happened?????jiant2520;4797581;4797581 said:Sorry about your situation. You just got this guy last week or so, right? I really can't tell what happened to him. Your GT or Oscar could have beat the heck out of him... have they shown aggr in the past towards any other fish? I've never seen markings like he has before, what ever they are.
