Depends....A tall hex tank is:
Length 18 inch by depth 13 inch by height 20 inch
A 20 gallon high is 24, 12, 16
A 20 gallon long... 30, 12, 12
And an x high tank is 20, 10, 34
There are many more but these are the most common.
Hope this helped :)
I assuming 25 cu-ft (cubic feet). 34.6 cubic feet of propane vapor equals one gallon of liquid propane. So, 25/34.6 = 0.72 gallons. Depending on the size of the tank, 25 on the gauge will be 25 percent of the total capacity of the tank. A 250 gallon tank will have about 62 gallons. The gauges are in 10 percent increments, so each number represented on the guage ex: 10,20,30,40,50,60,70,80,90, represents 10 percent of otal tank capacity. In a 250 gallon tank 10 would equal 25 gallons, 20 would equal 50 gallons and 30 would equal 75 gallons. Likewise in between these numbers would be 5 or whatever it appears to be closer to above or below 5.
20 rods = 330 feet.
20 LBS OF PROPANE WILL PRODUCE APPROX. 36,000 BTU @ 0 DEGRESS, 51,000 @ 20 DEGREES.
6.66 yards.
1 yard = 3 feet 20 yards = 60 feet
A 20 Gallon tank can hold up to 20 gallons of water.
1 cubic foot = 7.48 US gallons. Using the factor-label conversion method: 20 gallons x 1 cubic foot/7.48 gallons = 2.67 cubic feet
A 20-gallon tank can comfortably house around 5 to 7 mollies.
5 Gallons
The recommended number of shrimp that can comfortably live in a 20-gallon tank is around 20 to 30 shrimp.
either a 15 gallon tank or a 20 gallon tank
20 gallons
A 20-gallon tank can comfortably house around 6-8 white cloud minnows.
Either a 13 gallon or a 20 gallon tank.
no it cannot die in a 20 gallon tank because i have 3 baby lepord geckos in 10 gallon tank
About three or four
I agree that a 20 gallon tank isn't big enough and they won't be very comportable in it but ball pythons don't get longer than 20 feet,the longest a female would get to would be 5 - 6 feet and a male would get to about 4 - 5 feet but that's rare! You could use a 30 gallon tank but the best would be a 40 gallon tank for a fully grown ball python!!
