Bioload and Stocking Capacity
"Bioload" describes the quantity of biological waste a fish produces. A common general rule for newbies is the "One Inch of Fish Per Gallon" guideline. Nevertheless, modern-day aquarists generally consider this rule out-of-date and unreliable.

A 3-inch goldfish produces considerably more waste than a 3-inch tetra due to its diet and gastrointestinal system. Rather, aquarists determine equipping levels based upon total fish mass, purification capacity, and surface area.
3. Schooling and Social Requirements

A 20-gallon tank needs a filter rated for at least 100 gallons per hour (GPH).Heating: As a general guideline, fish tanks require 3 to 5 watts of heater power per gallon of water. A bigger tank requires either a higher-wattage heater or multiple heating systems put at opposite ends for even heat circulation.Lighting: If you prepare to keep live marine plants, tank height matters.
