Fish Tanks: Koller Products AquaView 4.5-Gallon

This Koller tank features seven distinct LED light colours and four transitions to highlight your fish and draw attention to it on a shelf or desk. The design of this tank is so straightforward that it’s an instant hit: it’s just a circular rectangle of acrylic with no seams or sharp corners. The power filter takes up very little room at the top of the tank’s back, allowing you to see the fish from any angle.

Dual-sided cartridges coated in poly-fiber floss strain out floating particles while the carbon cures discolouration and smells in the water. The filter is rather strong, so anyone maintaining long-finned or weak-swimming species may want to cover the input.

The tank is nearly leakproof due to its single-piece construction, and the bright LEDs illuminating down make it perfect for circumstances where it could be banged. Although it won’t withstand repeated abuse, anyone seeking for a tank for a child’s room might consider this one. The lights come in seven distinct colours: amber, aqua, blue, green, purple, red, and white. They may be set to cycle or to stay on a single hue.

Betta fish are popular among newcomers to fishkeeping because they can breathe from the surface via the labyrinth organ. The magnificent Siamese fighting fish is the most well-known member of the species, and while it should be maintained alone or with carefully selected tank mates, there are countless other bettas that lack its aggression.

Bettas, contrary to common opinion, can live in small spaces due to their breathing behaviours, although they prefer five-gallon tanks like this one. Bettas, like many other fish, require a water temperature of 76-81 degrees Fahrenheit, so if your environment is colder, consider purchasing a tank with a heater or adding one to this set.

Acrylic is used to make the tank, however unlike other scratch-resistant materials, it is easily scratched. This isn’t an issue after the tank is fitted, but it might cause issues during delivery. The tank is carried in its own container to prevent damage, although accidents can happen. The curved front looks wonderful once filled and illuminated, and the integrated Aqueon power filter takes up very little space.

Fish Tanks: Fluval Sea Flex

All-in-one aquariums like the Fluval Flex are great for beginners. Because of its All-In-One form factor, the aquarium is elegant and has a contemporary style that fits into any living space. The tank is constructed of curved glass that has a high level of transparency. The aquarium has a built-in three-stage filtration system. Nothing is suspended from the sides or rear of the tank. This looks great and makes putting the aquarium in your living room a lot easier.

Water particles such as trash, algae, and uneaten fish food are caught by a foam filter in the filtration system. A bag of activated carbon removes dissolved organics and yellow colours from water, resulting in crystal-clear water. The biofiltration stage eliminates harmful ammonia and nitrite from the water, which may cause stress and illness in the fish.

An internal water pump circulates water through the filter materials before returning it to the tank. The tank lid has an integrated LED lighting system. The light colours and timing may be controlled with the Flexpad remote control. You can even make your landscape more realistic by adding cloud cover and lightning!

Fish Tanks: MarineLand 5 Gallon Portrait Glass LED Aquarium Kit

The upright tank from MarineLand is sleek and beautiful, and it looks great in any context. Although five gallons of water isn’t much, it’s plenty to feed a thriving population of colourful fish provided filtration and upkeep are kept up.

A three-stage filter with replaceable activated carbon cartridges (you’ll go through one every month or so) and a Tetra submersible heater that’s already set to the proper temperature are included in the MarineLand tank.

The three artificial plants that come with the kit are enough to get you started, but you may find that you need more to complete the display. A wall of greenery that pushes the fish forward so you can see them better will look beautiful because the back of the tank is dark. Taller aquarium plants may be employed because of the tank’s height, which can appear extremely nice.

The tank is supported by its own weight on a sturdy plastic base, with a single piece of seamless glass on the front and sides. Lighting is provided by blue and white LEDs, which give the water a natural shimmering effect as it flows, as well as a moonlight appearance when switched on at night.

Fish Tanks: Vepotek NANO Kit

Because of their small size and distinctive look, nano aquariums are popular among some individuals. With the right accessories, they can look spectacular, and the Vepotek Nano accessories and features are a great place to start.

This nano “kit” already comes with a filter and lights. The lighting is one-of-a-kind since the 39 LED lights come in four distinct colours. A built-in timer is one of the many characteristics of the lighting system.

The aquarium is composed of glass, which adds to its overall aesthetic appeal. While acrylic offers a lot of advantages, it also has a lot of drawbacks, the most significant of which is that its surface is easily scratched. Because the material’s clarity deteriorates after a number of unintended scratches, some acrylic tanks don’t survive very long. Glass, on the other hand, is extremely scratch resistant.

Fish Tanks: Tetra Crescent Acrylic Aquarium Kit 5

Because of its curved face and sparkling LED lights, Tetra’s Crescent will stand out wherever it is placed. The front, which is constructed of one piece of acrylic with a separate lid and base, allows you to see your fish better.

On the interior, you’ll find the famous Tetra Whisper power filter, but you’ll need to buy a heater separately. This is OK if you simply want to maintain room-temperature fish, but if you want to keep bright, tropical species, you’ll need to add a heater to boost the temperature to around 77°F.

The LED lights are enclosed in a small black cover that is bright enough to support the growth of actual plants, but artificial plants will work just as well. Their intensity contrasts beautifully with the fish’s hues. The cover also contains an uncovered oval for feeding, which should be covered with a mesh panel to keep leaping fish from jumping overboard.

The filtering medium is disposable Bio-bags, which may be easily replaced out of the black, cylindrical filter. A dual-sided mesh collects floating debris, a carbon coating reduces smells and discoloration, and Tetra’s Water Clarifier prevents particles from accumulating in the water and on the glass. The Whisper filter is a popular choice, and it works silently if properly maintained.
