I too went with the brown...but that was cause I found it more attractive...not to say the blue isn't...its just as gorgeous...for some reason the brown drew me in more..
If I had gotten a naso ..then I wud have gone with the blue...but some folks advised against nasos
Rob,
Care to explain why delaying the addition of fish for few months would help...are u just waiting for the tank parameters to settle or for a source for them to feed off from the rock...isn't that something that will develop with time anyways as it matures.
