Fish Stocking Formula:
| From: | To: |
The Fish Per Litre Calculator helps aquarists determine the appropriate number of fish for their aquarium based on tank volume and fish size. It calculates stocking density using the standard guideline of 5-10 litres per cm of fish length.
The calculator uses the fish stocking formula:
Where:
Explanation: This formula ensures adequate space and water volume for fish health and wellbeing, preventing overcrowding in the aquarium.
Details: Proper fish stocking is crucial for maintaining water quality, reducing stress, preventing disease outbreaks, and ensuring the overall health and longevity of aquarium inhabitants.
Tips: Enter aquarium volume in litres and the recommended litres per cm of fish (typically 5 for small fish, 10 for larger or more active species). All values must be positive numbers.
Q1: Why is 5-10 L per cm the standard guideline?
A: This range accounts for different fish species' activity levels, waste production, and space requirements while maintaining good water quality.
Q2: Should I use the lower or higher end of the range?
A: Use 5 L/cm for small, peaceful fish and 10 L/cm for larger, more active, or territorial species that require more swimming space.
Q3: Does this account for filtration?
A: No, this is a basic guideline. Strong filtration may allow slightly higher stocking, but overcrowding should always be avoided.
Q4: What about different fish shapes?
A: This calculator uses length as the primary metric. For unusually shaped fish (very tall or wide), consider their overall space requirements.
Q5: Can I stock more fish in a heavily planted tank?
A: Plants help with water quality but don't replace the need for adequate swimming space. Always prioritize fish comfort and natural behavior.
