Intro and tank size preference

[banditpowdercoat]

Welcome, and would love to see pics.

Tank wise, I would go with the 48". As it's wider and taller. Much easier to aquascape, and lighting should be cheaper, although need more wattage to penatrate the depth. I think the skinny tanks lend themselves more to FW applications, as the fish can easilly swim through the plants and such. But, in SW, the rock takes up a large part of the tank.

Welcome to the non-lurking part of canreef.My tank is exactly the same size as your six footer. I would say, think about what fish you would eventually like to keep. If you think a small tang or two might be in your future than go with the six. The four footer will give you a broader choice of lighting options and the initial cost will likely be less.

Hands down a six footer. You get to keep tangs.

[StirCrazy]

the 4 footer is the better tank and no mater which tank you chose you can only keep one or two tangs depending on the type. the wider tank will actually be better for tangs as they can turn better while maintaining speed. a narrower tank they have to slow down and turn sharper. also a wider tank is alsoway better for setting up mass water flow, with out ending up with a jet type water blast.

I'd go with with 6 footer. Big tanks are pretty. Very pretty

I have the same dimensions actually and love it.
