To determine how many neon tetras can be housed in a public aquarium, you'll need to know the total volume of the aquarium in gallons. Once you have that information, you can use the volume requirement of each neon tetra to calculate the total number of them that can be accommodated.
The formula is:
\[ \text{Number of Neon Tetras} = \frac{\text{Total Volume of Aquarium (gallons)}}{\text{Volume per Neon Tetra (gallons)}} \]
Given that each neon tetra requires 1.25 gallons, you can plug in the total volume of the aquarium into this formula.
For example:
- If the aquarium is 100 gallons, the calculation would look like this:
\[ \text{Number of Neon Tetras} = \frac{100 \text{ gallons}}{1.25 \text{ gallons/tetra}} = 80 \text{ tetras} \]
If you provide the total volume of the aquarium, I can help you calculate the maximum number of neon tetras it can hold!
