That's not actually true. The surface area of the tank is a more important factor than pure gallons in determining stocking levels. That's because surface area determines how much oxygen gets dissolved in the water. Basically, you shouldn't stock a 29g tank any more than a 20g tank.NinjaSmurf said:Tall tanks are perfectly fine as long as you have enough filtration and the table can handle it, and you can get a bigger tank for more fish.
Keep it simple. If 10g is what you can do right now and it won't get your parents on your back, then go with it. Learn how to take good care of a small group of fish and show off your clean, healthy, active tank to your family. Who knows... maybe they'll see the light and get a bigger one?
Hope things go well, whatever you decide...
Good luck!
