What is the ideal tank size?

[terrance liow]

Hi all,

Can any one tell me that what size of single tank is suitable to
keep a single betta?[bt]

8"x8"x8" , 6"x6"x8",6"x6"x8" or any other size???[cnf]

Thanks for your advice. :)[ber]

Hi Terrance,

There's not fixed rule here. The bigger the tank the better - mah.
My best experience is anything that can hold a 1/2 gal. of water.

My vote is for "the bigger the better" as well. If you have a 5 gallon or larger tank you can put in a couple of live plants and a small filter.

I agree with Simon's and Steve's conclusions.

The size of the tank is especially important for bettas with huge caudals (e.g. half-moons). I noticed that as the caudal of the half-moon grows, the fish requires more effort to swim to the water surface for air. The drag/resistance that the half-moon experiences is very much like a fighter jet being slowed down by an opened parachute.

When they are housed in smaller (e.g. 4x4x8) tanks, bettas need to swim to the water surface at about 70 to 80 degrees to breathe. If they are housed in a bigger (e.g. 6x6x8, 8x8x8) tank, the angle is reduced to about 30 to 50 degrees (i.e. less steep). This angle is further reduced if the betta is living in an even larger tank.

Personally, I house my younger long caudal bettas in 4x4x8 tanks and switch them to larger tanks (6x6x8 or bigger) before they are fully grown, so that they can have more space to maneuver and surface for air when their tails become larger and heavier (especially half-moon bettas). As for plakats, I continue to house them in 4x4x8 tanks.

A 4x4x8 tank holds about 1/2 gallon of water, while a 6x6x8 tank holds about 1 gallon of water.

Proceed to the following thread to find out the volume of water that most people here use for their fancy/long caudal bettas.

For halfmoons, I am using 7(W)X9(L)X11(H) tanks.

Hi Myron,

Depending on the water level, each of your tanks should hold about 2 to 2.7 gallons of water (1 gallon is 231 cubic inches).

Very ideal for bettas with huge finnage.
