Nevertheless, modern aquarists usually consider this rule out-of-date and unreliable. A 3-inch goldfish produces substantially more waste than a 3-inch tetra due to its diet and gastrointestinal system. Instead, aquarists compute stocking levels based upon total fish mass, filtering capacity, and area.3. Education and Social RequirementsMany popular freshwater fish-- such as neon tetras, cory catfish, and baros-- are education or shoaling types. Keeping them alone causes persistent stress.

A 20-gallon tank needs a filter ranked for a minimum of 100 gallons per hour (GPH).Heating: As a general guideline of thumb, aquariums require 3 to 5 watts of heating system power per gallon of water. A bigger tank requires either a higher-wattage heater or numerous heating units placed at opposite ends for even heat distribution.Lighting: If you plan to keep live aquatic plants, tank height matters.
