Tall Vs Long Tanks

Just sorting out the basics. So, lemme see if I have this right.
A tall tank's advantage is more water (good! more wiggle room to recover from adverse water quality events) in a smaller space footprint (good!)

(And easier for fish that lives at different places in the water column vertically to establish their territory and stay out of other fishes way?)

The disadvantages of a tall: less oxygen per gallon because of less top surface area, and less room to swim horizontally for fishes that need that?

Am I even close? Are talls less suited for novices like me? Ask because there's a used 40 gallon on Craigslist w/stand and acc. for $40, and I can do a 40 gal tall way easier than a 40 gal long..

 

More surface room equals to more oxygen. Tall tanks imo is only suitable for fish like freshwater angelfish and discus, since they are tall.

I prefer a 40 breeder over a 40 tall. Also Petco is having a $1 per gallon sale going on this month.

 

Gallon for gallon a long tank can support more fish due to more exposed water surface area, this helps with O2/CO2 gas exchange. Also some species of fish require horizontal swimming room to be comfortable, if you are going live plants sufficent lighting needs to reach the bottom of the tank.

 

Hello!
This actually depends on your stocking but in my opinion, Length Size and Height size must be close enough.

I think Length should be 30 cm more than Height, That is How it will be good-looking or at least I prefer this method.

 

Thanks everyone that helps a lot!

 

Long

 

If you are planning on putting your goldish in their a long is better because they need lots of oxygen.
