I never had a mean Jaguar all of them have been pussies. period. Then again I never kept them past 5 inches... Got the feeling Jaguars were over-rated fish that couldn't even hang with an Oscar. My five inch girl has been bullied by a tiger oscar since August of 2014. The past two weeks she has been building a nest and flaring alot. This morning I was woken when something went nuts in the tank and I turned the lights on and my "wussy" was beating the living hell out of my oscar. Guess My stereotype was proven wrong. DONT underestimate your fish! learned this way for sure, I'm probably going to have to re-home the Oscar if things stay this bad. Can't wait for my Girl to grow some more! Hope to breed her someday
