Many people dream of their aquarium, but not everyone can have a large aquarium for various reasons like:
- Lack of money
- Lack of space
- Lack of knowledge on maintaining a big aquarium
A real alternative is a mini aquarium, which takes up very little space and does not require complex care. Pet stores offer many different types of aquariums, but they are all standard and a little boring.
Small aquariums are considered to be smaller than 7.9-10 gallons; usually from 1.3 to 5.2 gal. They are often called nano aquariums. There are also micro aquariums whose capacity is 0.2-0.5 gal, but fish can’t live in such an aquarium, except for some types of snails.
A mini aquarium is an ideal option for a desktop in the office or the schoolroom. The interior items can create an atmosphere of peace and tranquility, create conditions for concentration or allow you to distract yourself.
You can always make a mini aquarium yourself. Let’s look at the main stages of building a mini aquarium.
How to make a mini aquarium?
First, sketch the aquarium design. Remember that for fish, the volume should not be less than 1 gal. If such an aquarium is significant for you, then you should think about replacing the fish with beautiful seaweed or shells.
Prepare with transparent silicone, glue, glass and any degreaser. Use a glass cutter to cut the glass into the required size pieces. Degrease the edges with acetone or other solvent and glue them together. After drying, carefully seal the seams with transparent silicone and allow them to dry well. The accuracy and aesthetics of the final product directly depend on how slowly the work will be performed.
A round mini aquarium is better to make a transparent vase of the required size and shape.
Soil and plants for a mini aquarium
After the glue has dried, you need to take care of its design. The soil can consist of any aquarium stones, pre-boiled in a weak solution of potassium permanganate. You can choose stones of the original shape and color.
Mini aquariums are very convenient for growing some small species of plants because it is easier to create good lighting in a mini aquarium. In large aquariums, the light does not reach the lower level in the required amount.
Live plants are needed in small aquariums, as they help to remove dangerous substances from the water — nitrites, nitrates and ammonia. Also, plants in a mini-aquarium reduce stress in fish.
Plants for a mini aquarium and algae should be small in size so as not to take up space for fish to live in.
You can apply a special decorative film that simulates an underwater landscape or plastic aquarium plants, also.
Lighting and filter for mini aquarium
It is easy to light your mini aquarium – you only need to make a cover of glass, plastic or other material and equip it with a lamp, a powerful diode and a battery.
If your fish need oxygen-rich water, you should buy and install a small filter or compressor. If the inhabitants of the aquarium will be fish that can breathe atmospheric air, then the filter will not be required.
It is important to understand that the equipment of this type of aquarium with all types of devices will significantly reduce its aesthetic qualities.
What fish can be kept in mini aquariums?
In a small, 2.6-5.2 gallon tank, you can settle fish with miniature body sizes, up to two inches. But remember that even small fish want to swim in a spacious environment. You cannot keep fish in containers that will limit movement.
In mini aquariums, you cannot settle territorial and aggressive fish. Fish like swordfish, cichlids, gourami and danio are not suitable for a mini aquarium. These fish are active and energetic, and they need more space for hiding.
In 5 gallon aquarium, you can settle small fishes like barbuses, gertrudas, oryzias, rasboras, neons and tetras. You can also keep amano shrimp and cherry shrimp. Mind the size of your fish. With good care, the fish will grow and become cramped. Plant large fish in large home reservoirs and replace them with young ones.
The owner needs to buy a species of fish with a strong immune system. They also often settle well-known Siamese cockerels. A cockerel can live alone, and it doesn’t get along with relatives, as it is a fighting fish.
Carefully study the compatibility of species
Fish for a small aquarium should be selected depending on many factors. For beginners, it is difficult to observe all the nuances, so contact professionals who will help determine which fish can be kept together and which can not.
Important compatibility factors:
- Ability to survive singly. Some species can only live in flocks, so pay attention to this point first
- The characteristics of the water types should be approximately the same
- The peaceful character of the inhabitants
- The number of individuals depends on the surface area of the water
- Breed compatibility; sometimes peace-loving individual fish do not tolerate the neighborhood of each other
It is important to remember that small aquariums are a high-risk area for fish. Therefore, the choice of neighbors will completely determine the fate of your wards. You can have one fish that will be the mistress of your pond or keep a whole flock of miniature fish.
Caring for a mini-aquarium
Often parents buy mini aquariums for their children, believing that a small aquarium is easier to care for than a large one, but this is not true. The “underwater world” of a small size is subject to temperature changes and requires frequent water replacement.
If the water is rarely changed, fish waste begins to accumulate on the walls, and it will be quite difficult to clean the container with your hands. To prevent the appearance of algae, the aquarium should not be placed close to the window – it should not be exposed to direct sunlight.
With such a small amount of water, a drop of even a few degrees negatively affects the fish. Feed the fish a small amount of food so that there are no leftovers after feeding. The slightest excess of food that has lain at the bottom of such an aquarium instantly spoils the water, so remove the excess feed immediately.
You will need to change the water frequently, and a stock of settled water should always be nearby. Replacement of water in the aquarium should be carried out every three to four days, replacing at least a quarter of the volume of water in a small aquarium.
Design of a small aquarium
There are many forms of a small aquarium: cube, glass, trapezoid, hexagons, etc.
If you choose a small round aquarium, remember that outwardly round and rectangular aquariums may seem the same size, but a round aquarium always has a smaller volume.
You can create a nano-aquarium in different styles. You can decorate your aquarium with stones of different shapes, snags, or plants.
For the design of small aquariums, moss (small pieces) or Hemianthus are most often used, and from plants –Anublas, Microsorum and Vesicularia.
In the case of small aquariums, the appropriate solution is to abandon the fish and populate the reservoir with shrimps completely. In addition, if there are shrimps in the aquarium, you should keep in mind that any objects protruding from the water can contribute to their escape from the aquarium.
The advantages of mini models include the ability to place them almost anywhere: on a table, bookshelf or in a wall. This aquarium is easy to transport, and you can quickly and easily relocate it.
The tank is also perfect for depositing young or mating fish. You can use it as an insulator, removing sick or newly acquired individuals.
As a rule, these miniature aquariums are sold complete with all the necessary equipment. Pump, filters, lighting – all neatly and securely mounted in the product itself; there are no extra wires.
