I have very very few true GTs left. And they are stunning fish as adults (BOTH females and males). I completely disagree on the true GTs looking like silver or gold saums, there's plenty of differences, including the tons of RED in the fins.
That said, there are tons of gorgeous Aequidens and "Aequidens" like fish out there. But let me know if you're interested in true GTs and I might be able to help you out!
