I have kept aquariums all my life, but I am finally getting a big one... looking at an 8 foot 240. I have a pair of MEAN severums (my hand goes in the tank, I bleed), a 8-10 inch female jag, and a large pleco I am going to put in it. What would be a neat not so common fish or 2 to go with them? I am thinking maybe a festae?
