Fish Stocking Formula:
| From: | To: |
The Fish Per Litre Calculator helps aquarium enthusiasts determine the appropriate number of fish for their tank based on the standard stocking guideline of 1 cm of fish length per 4 litres of water.
The calculator uses the fish stocking formula:
Where:
Explanation: This formula provides a general guideline for stocking density, ensuring adequate space and water quality for healthy fish.
Details: Proper fish stocking is crucial for maintaining water quality, reducing stress, preventing disease, and ensuring the overall health and wellbeing of aquarium inhabitants.
Tips: Enter your aquarium volume in litres and select whether you want to calculate fish count or litres needed. For fish count calculation, the result shows how many cm of total fish length your tank can support. For litres needed, enter your desired fish count to determine the minimum tank size required.
Q1: Is this calculator suitable for all types of fish?
A: This provides a general guideline. Some fish species have specific requirements - large fish, messy eaters, or territorial species may need more space.
Q2: What does "cm total per L" mean?
A: It means the total combined length in centimeters of all fish should not exceed 1 cm per 4 litres of water. For example, in a 100L tank, you could have 25 cm total fish length.
Q3: Should I consider filtration when stocking?
A: Yes, this is a basic guideline. Effective filtration, water changes, and tank maintenance also affect how many fish you can safely keep.
Q4: Are there exceptions to this rule?
A: Yes, heavily planted tanks, advanced filtration systems, and experienced aquarists may be able to stock slightly more heavily, but beginners should follow this guideline closely.
Q5: How does fish growth affect stocking?
A: Always consider the adult size of fish, not their current size. Many fish grow significantly and will need more space as they mature.
