Hey i was just thinking because i have such limited space can i get a 15 high tank instead of a long or standard? Or do they need that extra length? And either the BP or Ob peacock would go in there.

length and width = surface area. its the surface area that allows the oxygen to enter the tank. the more surface area you have the better. small surface area means small fish only can be kepted (

in my place, any tank that have a 3 ft long will always have at least
18 inches high.... 12 inches high is normally intended for a two footer
tank only....

a wider lateral surface area for swimming is always an advantage...
i can only concur with marcus...

marcus is spot on. You can have more fish in a 4 x 2 x 1 (LWH) than you can in 4 x 1 x 2 due the higher surface area in the 1st case

longer and shorter is better

Okay just wanted to check first that would of been easier maybe i could get a 30 high and tell my dad its only a 15 then the one fish (or two) i put in there would have more room. Or would that not even be good enough.

It volume for fish waste and filtration, surface area for oxygen

well what if i had bublers?

bubblers wont make a difference.

But wouldnt an air curton airate the tank?

yes but that still doesn't mean you can have more fish...

Eather way if i put even one fish in there itd have more room in a 30 gallon high than a 15 gallon normal?
