Your Green Terror is beautiful 
Although, having the Buttikoffri in the same tank means trouble eventually... IMO as the Buttikoffri grows, he will not stop until he is king... If he is not king he will create so much stress on your Green Terror until he will not look as pretty as he does know. Also, I didn't notice the Dovii, yes this will be too much stress for your Green Terror, Dovii will not let the Green Terror be king forever. 180 gallon is not enough tank to have Dovii, Green Terror, and Buttikoffri in it. Green Terror are just not built to battle like Dovii, and Buttikoffri. Although this is just my experience... I would hate to see the Green Terror go down hill from beauty to ugly...
