I will take the duel 180's off your hands for free and then you can get your 330 gal

Keep them all, but setup the 600 IMO. Give that regal fish some space to stretch!

I would make room! I removed my entertainment center to make way for a 300g. Don't regret it at all!

The 300 is the entertainment center

I would go 330 and keep 180 at the bottom if at all possible. Setup you have now looks great!!1 Someone say 600????

Since you have a larger tank already I'd hang on to the 180 gals.
