How to Choose The Best 15-gallon Fish Tank
Choosing an aquarium is always a delicate task. It is a basic “tool” for hobbyists. If you make a mistake in the device, it will cost you money, time, worry, and failure. The purpose of this sheet is to give you an overview of buying equipment and aquariums.
Often, you will find promotions with aquariums, filters, heating, and lighting. Sometimes these promotions are financially interesting, but sometimes there are major flaws. I recommend that you check that the elements of the package match the size of the aquarium and the advice below.
Aquarium volume
The internal volume of the aquarium is the first consideration. Too small a volume will give you more problems than a larger volume, will raise less fish, and will force you to restrict small fish.
You can choose an aquarium from 15 gallons to 50 gallons, depending on your needs.
Gallery, illumination
When buying an aquarium, gallery selection is critical. The gallery must provide proper lighting as well as simple, easy, and complete access to the aquarium’s materials. Because a beautiful collection typically makes up the aquarium’s price, replacing it later is inconspicuous. Don’t buy an aquarium with a small collection.
To clean the aquarium, you must have easy access to almost all of its contents. The collection should be as open and simple as possible. Furthermore, neon tubes should not obstruct aquarium access. Gallery lighting must be neon-based or be prohibited owing to poor quality. Adjust the quantity and power of the neon lights to the tank’s capacity.
The stronger the light (and neon lights), the larger the tank. These are fundamental because plants cannot flourish without sufficient energy. Because adding neon lights to an existing collection is difficult or impossible, the gallery’s vitality must be embraced from the start.
Filter
Aquarium filtration should never be overlooked. Unseen organic waste pollutes water; hence, an aquarium filter is needed. The filter converts organic components into fish-friendly elements, allowing just a 15% weekly change of aquarium water. All water would be replaced daily without the filter!
Avoid cheap internal filters with filter foam or activated carbon cartridges at all costs. They filter a small volume of water without treatment. purely organic. Troubleshooting or backup filters. Avoid filters beneath the sand—suction nets. These fairly efficient filters clog easily and are only for small aquariums.
Therefore, you can choose between internal and external “settling tank” filters. Exterior filters are better but require a piece of furniture to hide them. Internal sediment filters are usually a bit less efficient and are not scalable; they are difficult to remove as they are strongly trapped in the walls of the aquarium. On the other hand, it “eats” a large portion of the space inside our aquarium, which is a shame.
Remember that the filter does not necessarily come with its filter media, so you will have to buy foam, personal pads, and other ceramics that match your filter. Ask the seller for advice. The flow rate of the filter pump must be adapted to the size of the aquarium.
Heaters
Heating is essential if you want to place tropical fish (often more diverse and colorful than freshwater and cold water fish). The heating capacity depends on the minimum room temperature and the desired water temperature (usually 25 ° C). If these parameters are not known accurately, the easiest way is to use an overheated boiler.
A bubbler
Aquarium aerators are a useful device even if they will not be used permanently (unless you don’t want plants to live). The bubbles are very helpful when starting the aquarium, in the summer, during a nitrite problem, or after drug-based treatment. So even if bubbles are not always helpful, you have to buy them from the beginning.
The accessories that come with air bubbles are flexible and transparent air hoses, air diffusers, and non-return valves. The size of the bubbles must be adjusted to match the size of the aquarium, the bigger the tank, the stronger the foam will be.
Aquarium floor
Aquarium floors are important if you want to place live plants. It really should be good support for the latter (thick enough, cool, and nutritious). The soil will consist of a sand surface that is the best selection for a dark color and average particle size (from 0.25 to 0.5 mm).
Indeed, too-rough sand is not beautiful and is filled with waste quickly, but too-fine sand is not easily cleaned and does not facilitate soil breathing.
The soil bed will consist of an aqua base (or Aqualite) or a homemade mixture (15% clay, 35% clay soil, and 50% sand). Between the two layers, it may be helpful to place a plastic net (which you can find in all DIY stores); this prevents the nutrient layer from rising.
Other necessary accessories
There are many accessories that we will only introduce here that may be useful for beginners. Here is a list of accessories and products that you must buy at the same time as your aquarium:
- The neon tube adapts to your collection.
- A landing net to handle fish;
- An alcohol thermometer to control the temperature of the tank;
- A mechanical timer for lighting;
- An encyclopedia on fish and plants like Mergus;
- A water conditioner like Tetra’s AquaTan;
- Bacteria live to start the filter (eg Bacnet);
- A stimulant for bacteria like Tetriv’s Nitrivec;
- Nitrites (NO2-), Nitrates (NO3-), pH and Hardness (TH or GH) tests;
What to know about a 15-gallon tank
You may add several accessories to an aquarium you buy. An aquarist should buy a few items for the tank. A neon tube that adapts to your collection, a landing net to capture fish, a thermometer, a water conditioner, a mechanical timer for lights, nitrites, nitrates, pH, and hardness tests, and more.
These are two things that may help most beginners and prepare them for any situation. After your fish tank starts, you should buy online and floating plants for it since fish might use it as food if you forget to feed them.
One or two trees, tiny plants, etc. may be in the aquarium’s front. Your plants should match the pH of your water. Your fish need the appropriate water temperature. You must also consider how many fish you can fit in your tank without overcrowding it, and so forth. Continuous scenario. It’s fun.

Some other information
The list given above is an essential list for a good start to the aquarium. Once the aquarium is in water (say, after a day or two), it will be necessary to think about buying plants.
You should choose plants for the front of the aquarium (small plants), for the middle (medium trees), and for the bottom (large trees) of the aquarium. Plants must be compatible with the pH of your water. Take a pH test and list the plants you can order. The bigger the fish tank, the more plants. Consider buying from 5 to 60 plants, depending on your aquarium size.
At the end of 3 or 4 weeks, you might consider introducing your first fish (not before because it starts to establish a biological equilibrium; if you don’t respect this rule, the fish will not live long). To choose your fish, they must be compatible with the pH and water hardness (use the tests you bought).
An example: for 120 liters, we can place up to 20 adult fish under 6 cm. Do not place more than 20 fish because you will face serious problems. If you order only very small fish (up to 4 cm), you can place up to 30 absolutes.
