The internal 3-stage filter system with mechanical, chemical, and biological filtration will help keep your water crystal clear. The filter is hidden in the back wall of the aquarium.

The filter also includes Bio-foam to help in biological filtration.
The aquarium also does not come with a heater, which is necessary for keeping tropical fish.
Blue and white LEDs are mounted in the attached light rail. The lights can be switched from white, to blue or both. The blue LEDS enhance the colors of fish, plastic plants, gravel and ornaments. It also creates a relaxing moonlight effect.
The Marineland Silhoutte aquarium is best suited for small freshwater fish, shrimp, a frog, or a betta.

Fluval Evo V Marine Aquarium Kit
The Fluval EVO V is designed for keeping marine fish, reef invertebrates, and coral. The aquarium is constructed of glass with a volume of 5 gallons. This puts the Evo V in the nano aquarium class of marine aquariums.
The aquarium kit comes with a bright 11000K high-output LED light encased in a sleek aluminum housing that is a blend of white and blue LED lights. The LED light is designed for saltwater corals but is not compatible for freshwater plants.
The 3-stage filtration system (mechanical, biological and chemical filtration) is mounted inside the aquarium to one side of the tank. The black honeycomb pattern helps the filter box blend in. The filter has a relatively large area for adding filter media. It comes with a Fluval foam filter block with handle that makes maintenance easy. The filter also comes with Fluval Biomax bio media and activated carbon for clear water.
The Fluval Evo V is best suited for small reef fish and soft corals. Large and small polyp stony corals will require better lighting and a protein skimmer. You’ll also need to add a submersible heater to maintain a steady water temperature.
Overall this is a great starter small saltwater aquarium kit with an attractive design and a super-clear glass. While the price may seem high, you really get what you pay for with this small fish tank.
Hygger Horizon 8 Gallon LED Glass Aquarium Kit
The Hygger Horizon Aquarium measures 19" L x 11.8" W x 9.6" H, which still makes it small enough to fit on most desktops. This small fish tank features a curved front which widens the view of the aquarium. While it is a 8-gallon tank it only holds 6-gallons of water because of the detachable 3D rockwork background. When it is full of water and has a layer of gravel, the tank as a whole will weigh around 70-75 pounds. The tank has a cushion pad on the bottom to prevent scratches.
The tank includes a 7W 110GPH internal power filter pump with adjustable water flow and 2 rain showers that add a nice water noise. The 3D rockwork background also has a hole specially cut out for the filter.
Also included is an 18W white+red+blue LED lighting system with an external digital controller. The controller has a timer that can be set for 3-,6-, or 12-hour increments, can adjust the brightness from 10% to 100%, and has 3 light modes. The different light modes will really highlight the colors of your aquarium while also allowing you to simulate both daytime and nighttime conditions.
Bottom line, we really like this tank! It is very attractive - especially with the curved front and 3D rock background - and comes with a lot of great features for the money.

The Tetra Hexagonal 1 Gallon Bubbling LED Aquarium Kit falls into the Pico aquarium category. It holds just 1 gallon of water and measures 8 inches high by 6.5 inches wide and 6.5 inches deep. Its small size means this aquarium will fit just about anywhere.
