Small aquariums are not recommended for beginners because they are more difficult to maintain, more prone to fluctuations in water quality, and more restrictive in terms of fish selection. A larger aquarium, on the other hand, offers more stability, more diversity, and more room for error. In this article, we will explain why small aquariums are challenging for beginners and what factors to consider when choosing an aquarium size.
Small aquariums, also known as nano tanks, are generally defined as those that hold less than 10 gallons of water. While they may seem appealing for their compact size and lower cost, they pose several challenges for novice aquarists. Some of these challenges are:
Water quality: Small aquariums have less water volume, which means that any waste or toxins produced by the fish and plants will accumulate faster and have a greater impact on the water parameters. This can lead to ammonia spikes, pH swings, and other harmful conditions that can stress or kill the fish. Small aquariums also require more frequent water changes and testing to keep the water quality in check.
Temperature: Small aquariums are more susceptible to changes in temperature, especially if they are placed near a window, a heater, or an air conditioner. Temperature fluctuations can stress the fish and make them more vulnerable to diseases. Small aquariums also need a reliable heater and thermometer to maintain a consistent temperature range suitable for the fish species.
Filtration: Small aquariums need a powerful filter that can handle the bioload of the fish and plants, but not too powerful that it creates too much water flow or noise. Finding the right balance can be tricky, as some filters may be too large or too small for the tank size. Small aquariums also need a backup power source in case of power outages, as the filter is essential for oxygenating the water and removing waste.
Fish selection: Small aquariums limit the number and types of fish that can be kept in them. Most fish need more space than what a small aquarium can provide, both for swimming and for territorial reasons. Overstocking a small aquarium can lead to overcrowding, aggression, stress, and disease. Small aquariums also limit the options for compatible tank mates, as some fish may be too aggressive, too shy, or too sensitive for a small environment.
Larger aquariums, on the other hand, offer several benefits for beginners and experienced aquarists alike. Some of these benefits are:
Water quality: Larger aquariums have more water volume, which means that the waste and toxins produced by the fish and plants are diluted and have a lesser impact on the water parameters. This makes the water quality more stable and less prone to fluctuations. Larger aquariums also require less frequent water changes and testing, as long as they are not overstocked or overfed.
Temperature: Larger aquariums are more resistant to changes in temperature, as they have more thermal mass and can retain heat better. Temperature fluctuations are less likely to occur in larger aquariums, as long as they are placed away from direct sunlight, heaters, or air conditioners. Larger aquariums also have more options for heaters and thermometers that can suit the tank size and the fish species.
Filtration: Larger aquariums have more space for filters that can handle the bioload of the fish and plants. Finding the right filter for a larger aquarium is easier, as there are more models and sizes available that can match the tank size and the water flow preferences. Larger aquariums also have more room for backup power sources, such as battery-operated air pumps or generators, in case of power outages.
Fish selection: Larger aquariums allow for more and diverse fish that can be kept in them. Most fish can thrive in larger aquariums, as they have more space for swimming and for establishing territories. Larger aquariums also offer more possibilities for compatible tank mates, as there are more fish species that can coexist peacefully and harmoniously in a larger environment.
Choosing an aquarium size depends on several factors, such as the budget, the space, the experience level, and the personal preference of the aquarist. However, some general guidelines to follow are:
Start with the largest aquarium you can afford and accommodate: A larger aquarium will give you more flexibility, more stability, and more enjoyment in the long run. It will also save you time and money on maintenance and upgrades. A larger aquarium will also allow you to keep more and diverse fish that can suit your taste and personality.
Research the fish species you want to keep: Different fish have different requirements for tank size, water parameters, temperature, filtration, and compatibility. Before buying any fish, make sure you know their needs and preferences, and whether they can fit in your aquarium. A good rule of thumb is to allocate at least one gallon of water per inch of fish, but this may vary depending on the fish species and the tank shape.
Consider the plants and decorations you want to add: Plants and decorations can enhance the appearance and the health of your aquarium, but they can also take up space and affect the water quality. Before adding any plants or decorations, make sure you know their benefits and drawbacks, and whether they can complement your fish and your aquarium. A good rule of thumb is to leave at least 50% of the tank space open for swimming and circulation.
Conclusion
Small aquariums are not recommended for beginners because they are more difficult to maintain, more prone to fluctuations in water quality, and more restrictive in terms of fish selection. A larger aquarium, on the other hand, offers more stability, more diversity, and more room for error. Choosing an aquarium size depends on several factors, such as the budget, the space, the experience level, and the personal preference of the aquarist. However, starting with the largest aquarium possible and researching the fish species, plants, and decorations beforehand can ensure a successful and enjoyable aquarium hobby.
