Attention! Remember that you should stock 1 inch of fish per gallon or two of water so they can survive and grow.
Inches (cm) | Gallons (liters) |
---|---|
1 inch (2.54 cm) | 1 gallon (3.78 liters) |
2 inches (5.08 cm) | 2 gallons (7.57 liters) |
3 inches (7.62 cm) | 6 gallons (22.71 liters) |
4 inches (10.16 cm) | 8 gallons (30.28 liters) |
5 inches (12.70 cm) | 10 gallons (37.85 liters) |
6 inches (15.24 cm) | 12 gallons (45.42 liters) |
7 inches (17.78 cm) | 14 gallons (52.99 liters) |
8 inches (20.32 cm) | 16 gallons (60.56 liters) |
9 inches (22.86 cm) | 18 gallons (68.13 liters) |
10 inches (25.40 cm) | 20 gallons (75.70 liters) |
Fish
Choose a stunning solitary fish like a Betta or Dwarf Gourami, as they are not only visually captivating but also relatively low-maintenance, making them ideal for beginners who are just starting their aquarium journey.
Tank
A 5 gallon aquarium provides stability and space for your single fish to thrive within the tank and also reduces the frequency of fluctuations in water parameters, making it easier for beginners to maintain a healthy aquatic environment.
For example, betta fish grow no more than 3 inches. Therefore, 3-5 gallons of water is enough for her.
Equipment
Use a small filter and heater if needed. A filter helps keep the water clean by removing debris and harmful substances, while a heater ensures the water temperature stays within the ideal range for your fish, promoting their overall well-being.
Additionally, consider adding some decorative elements like plants and rocks to create a natural and aesthetically pleasing habitat for your fish.
Small Community Tank
![A lot of small fish inside tank. A lot of small fish inside tank.](https://florafish.com/images/best-pet-fish-for-beginners/s/8.webp)
Tank
Since a small fish community contains between 6 and 13 fish, let's imagine that one fish is 2 inches long. For this quantity, choose an aquarium between 12 and 26 gallons. Depending on the size of the fish.
Fish
Choose peaceful, small fish that can coexist in a small space. Examples include Neon Tetras, Cherry Shrimp, and Corydoras Catfish.
Equipment
The equipment is the same kit, which includes a larger filter system and a heater. In addition, you will need lighting, but this depends on the size of the aquarium.
Medium Community Tank with Active Fish
![Medium fish in a medium tank. Medium fish in a medium tank.](https://florafish.com/images/best-pet-fish-for-beginners/s/9.webp)
Tank
This is an average aquarium with a capacity of 10 to 20 fish. Based on the information above about how much water you need to use per inch of fish, you will need a tank that is between 20 and 40 gallons in size.
Fish
Consider active fish like Platies, Swordtails, and Rasboras.
Equipment
Since the medium fish community is larger than the others described above, you will certainly need ample decorations such as rocks and live plants, a larger filtration system, a heater and lights.
Conclusion
