If you could do it all over...

I would have gone with external overflows for sure and definitely would have gone with a bigger tank. I have a 180 now but I would like to have gone 10'. I will hopefully get to do this very soon. Also I would have gone with a different selection of fish. I currently have many common fish and would like to have done some rarer specimens. The bigger tank should allow me to do this.
