Fish Tank Stocking Formula:
| From: | To: |
The Fish Tank Fish Calculator estimates the maximum number of small fish that can be safely housed in an aquarium based on tank volume. It follows the general rule of thumb for fish stocking density in home aquariums.
The calculator uses the fish stocking formula:
Where:
Explanation: This formula follows the common aquarium guideline of approximately 1 inch of fish per gallon of water, with an average small fish being about 1 inch in length.
Details: Proper fish stocking is crucial for maintaining healthy water parameters, preventing overcrowding stress, and ensuring adequate oxygen levels for all aquarium inhabitants.
Tips: Enter your tank volume in gallons. The calculator will determine the maximum number of small fish recommended. Remember this is a general guideline and may vary based on fish species, filtration, and maintenance routine.
Q1: What counts as a "small fish"?
A: Small fish typically refers to species that grow to about 1-2 inches in length, such as neon tetras, guppies, or small danios.
Q2: Does this apply to larger fish?
A: No, for larger fish you need to account for their adult size and bioload. A 10-inch fish would require much more space than ten 1-inch fish.
Q3: What about filtration and maintenance?
A: This is a basic guideline. Heavily planted tanks with excellent filtration may support slightly more fish, while poorly maintained tanks should stock less.
Q4: Should I stock to maximum capacity immediately?
A: No, always stock gradually to allow your biological filter to establish and adjust to the increased bioload.
Q5: Are there exceptions to this rule?
A: Yes, some fish have special requirements. Goldfish, for example, produce more waste and need more space than this guideline suggests.
