1. What is the Aquarium Fish Calculator?

The Aquarium Fish Calculator helps determine the maximum number of fish your aquarium can safely support based on the surface area. It uses the standard "inch per fish" rule adjusted for metric measurements.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{max\_fish} = \frac{\text{surface\_area\_cm2}}{12} \]

Where:

\( surface\_area\_cm2 \) — The water surface area in square centimeters
\( 12 \) — The conversion factor (1 inch of fish per 12 cm² of surface area)

Explanation: The calculation is based on the oxygen exchange that occurs at the water's surface, which is critical for fish health.

3. Importance of Proper Fish Stocking

Details: Proper fish stocking ensures adequate oxygen levels and prevents overcrowding, which can lead to stress, disease, and poor water quality in your aquarium.

4. Using the Calculator

Tips: Measure your aquarium's length and width in centimeters to calculate surface area (length × width). The result is a general guideline - consider fish size, species compatibility, and filtration capacity when stocking.

5. Frequently Asked Questions (FAQ)

Q1: Why is surface area more important than volume for fish stocking?
A: Surface area determines oxygen exchange capacity, which is more critical for fish health than total water volume.

Q2: Does this calculator account for different fish sizes?
A: The calculation assumes average-sized fish (about 1 inch/2.5 cm in length). For larger fish, you'll need fewer individuals.

Q3: What about fish that swim at different levels?
A: While some species utilize different water columns, all fish depend on surface oxygen exchange, making this calculation universally applicable.

Q4: How does filtration affect stocking capacity?
A: While good filtration can help maintain water quality, it doesn't increase oxygen exchange capacity, so surface area remains the limiting factor.

Q5: Should I stock to the maximum capacity immediately?
A: No, always stock gradually and monitor water parameters to ensure your aquarium's biological filtration can handle the bioload.
