what size would you get?

im considering getting a new tank, but im not sure what size I should get.

Im not sure if I have enough room for a 72" tank.. so is there any advantages between a 120g tank and a 125g tank? (one is 72" and the other is 48"

which would be better suited for the fish?

Also, if I got a tank this big, would a Magnum canister filter, and a emperor 400 be enough filtration for it?

Im either going for a 120/125 *hopefully* or a 90g

Mainly, im gonna have to find out how much space I have, because if I cant find anywhere to put it, I may have to transfer the fish from my 48", so a 90g tank wouldnt be practicle.. (half of thos post is a rant, lol)

What type of fish do you have or are you planning on adding? How many of each kind?

5g shouldn't make too much of a difference, but it seems (from your inch measurements) that one is tall and one is long. Tall tanks don't offer as much surface area, hence there is not as much oxygen available for your fish. Therefore, you can house less fish in a tall tank than in a long tank of equal size.

I thought you were just going to ask how big of a tank we'd all like... my dream tank is a 500gal.

A 120 is only 2" higher so the surface area of the 2 tanks is actually much the same. The 120 is just 6" wider. I don't think it would really matter but it does depend what your doing with the tank. Some fish would like the length, some may like the width, and certain setups may be easier to do in one or the other.

I absolutely hate magnum cannisters. I had nothing but trouble with mine. I refuse to ever touch another one after all the water that ended up everywhere on many occasions. Never did get it to work right and I tried to set it up many times on 3 different tanks over the course of a year. I'd spring for a better cannister(pretty much any other brand really) or run two emperor filters instead. I do love marinelands penguin and emperor filters and had a 90g setup with two penguin 330s that had no trouble.

Hi,
I don't see a flag by your name so I'm not sure if you
are in the States or not. If you are I have seen 120G,
125G, and 150G tanks in Petsmart. They even have a 150G
"high" tank that, I think, would be ideal for fish such
as angel fish with their body styles. The 120,125,150G
tanks all fit in a 6 foot, "footprint." The 150G high
was a smaller footprint, probably more like a 90G.

As to the difference between the 120 and the 125G tanks,
I would go by price. It would be interesting to find
out what that "extra" 5 gallons costs.

Obviously, you need to get out a tape measure and wander
about the house looking to see if you actually have room
in a place where you can sit and enjoy the tank first.

thanks, i found out lastnight that i can fit a 6' tank no problem.

also the difference between a 125 and a 120 gallon is one is 6' and the other is 4', the 6' tank (120g) will most def. be more expensive.

i wonder is a 150 tall will fit on a 2nd floor

Second floor tanks make me nervous (unless they're fairly small). Keep in mind that 1 gallon of water = 8 pounds, and when you add substrate, fish, and decorations, it's more like 10-12 pounds per gallon. So a 150-gallon tank would weigh between 1500 and 1800 pounds.
