Common fish tank sizes and characteristics

In general, increase the size of the tank by 10 gallons for each additional goldfish. You should try doing more research to find out what size cage ppl recommend. I know that for ACF, I've been told that 30 gals is the smallest tank one frog should have - from other ppl I've heard 10 gals per each frog. But the more space the better, because they need the space to swim and for hides. I wouldn't think that 10 gals would be enough for an adult bullfrog since they get pretty big.

This is a typical 10 gallon tank measuring 20-inch length, 10-inch width and 12.5-inch height.

Many people are skeptical about the limitations on tank size for goldfish because they go to pet stores and see 20 fish crammed into a 10 gallon tank. What they do not realise is that the actual water volume is a lot more than 10 gallons - a pet store will circulates water through all of their tanks from a common, central 3000 gallon tank, for example! Unless you are doing the same in your home aquarium, you need to restrict the number of fish according to the size tank you have.20-gallon (76 litre) tanks

Tanks this size are ideal starting points for anyone entering the hobby. In the United States 20-gallon tanks are available in “tall” and “long” varieties. The tall tanks measure roughly 24 inches in length and 17 inches in depth; the long tanks are 30 inches in length and 13 inches in depth. All else being equal, the long tank is better. Long tanks offer more swimming space and have a greater surface area to volume ratio, meaning oxygen diffuses into the tank at a faster rate. You can keep more fish, more happily, in a long tank than a tall tank.
Do tall 20-gallon tanks have any advantages? Not many. They are perhaps a bit easier to decorate with tall plants and rocks, and having a smaller footprint they take up less space on a tabletop or shelf. Greater depth does work better with certain small but tall fish, in particular domesticated angelfish. But beyond that, these tanks are far inferior to long tanks for general fishkeeping and are best avoided by less experienced hobbyists.
