Congratulation on your new fish collection, 
you now own my 3 favorite fish of all time. All you would need is a dovii and a pike and your set. Since people are giving advice I would recommend keeping the umbees isolated I am willing to bet you will lose a fish or two if you dont. I realize you may think there is no major threat giving there size, however, there more liable to die if they face a worthy adversary. Read up on the umbee requirements and wants. I wish you the best with your umbees there truly worth owning. 
Pictures please
