I am sorry for your losses, that EBJD was a looker. I know you want something big and mean that could extinguish the lives of countless small fish, but a 55 gallon tank isn't enough. A 55 gallon is too narrow to house the monster fish you want. I experienced the same mistake when I first got my 55 gallon tank and I eventually had to upgrade. If you can't upgrade, then I would agree with what others have said and try to set up an african tank or you could save up your money and get another EBJD and a bunch of tiger barbs
