*gasp* Jag with Con, Sev, and FM? Oh my! Uhmm...ok...all fishes in that 45g tank have different temperament too.
DarthV is right on one thing, Jag grows big and fast. That 45g tank will not hold Jag down long. Soon Jag will feel he/she needs space. I guess you can imagine what will happen from there.
As for Green Terror...DarthV has answered that question. He is also right about GT will not fit in that 29g tank. However, if you want to know what those 2 GTs look like, check out this site.
www.cichlidscene.com
and go to the Gallery. You will find both of those GTs listed there. Silver Saum is harder to get than Gold. I think Jeff Rapps had few on sales last month.
BTW, I did a search on the website. I couldn't find Royal GT. Where did you learn about this GT?
