Just seeking a little advice....I would like to have a Green Terror, Jack Dempsey, Red Devil and a Jaguar cichlid, and I'm purchasing them as all juviniles. Question is, would you start off with maybe a couple of Jack's then add the more aggressive fish later? I also intend of putting a couple Red Hooks in there as well ,and I know I'll need a much larger tank eventually if I want to keep them all together.....
