Sorry I just saw that now.
I also read in another thread that you have a Jardini in your 30 gal? When your 180 is ready the Jardini will be the only fish you can keep in there because they tend to kill all their tankmates. If you plan on selling the Jardini, you could probably keep a few GT's in the 180. Another thing to consider is that if you have males and females together, breeding will most likely occur whether you plan to or not. I think your main decision right now though is if you want to keep a Jardini or GT's, but not both.
Good luck.
