The Biocube Fish Tank really is one of the best starter fish tanks you can buy, especially for saltwater, but it makes a great freshwater tank as well. It comes in three sizes: 14, 16, or 32 gallons.
The Biocube looks amazing once the set-up has been completed. With a sleek black cover and frame, rimless front, and LED lighting, your coral and livestock will be displayed in all their vibrancy.

Either of these size options makes for a great starter freshwater or saltwater tank that can house a variety of fish.
Many people start off with a Biocube for their first saltwater tank, but many experienced fish keepers also pick them up. They don’t take up a whole lot of room, so they’re popular kits for apartments and other small living arrangements.
Biocube Features
This video gives a good run-down on some of the unique features of the BioCube tank.
These features include:
- Dimensions: 20.2 long x 21.9 wide x 21.5 high
- Weight: approx. 50 pounds
- LED lighting – designed for a saltwater tank
- Hinged fish tank cover – makes maintaining water temperature much easier
- A hidden filtration system built into the back of the unit can be customized
The LED lighting included with this starter fish tank is one of the best-selling points.
LED lighting is one of the best systems for a saltwater tank, encouraging strong growth of both hard and soft corals, and bringing out the colors of your fish. The lighting is set to a 24-hour timer and automatically shifts to replicate natural sun and moon cycles.
Bright white LEDs light up the tank during the day and change to blue for the night. What’s even better is that there is automatic lighting to replicate the sunrise and sunset, and the moonrise and moonset.
There is also a setting for color-enhancing LEDs. These are a combination of red, green, and blue LED lights.
The BioCube kit includes:

BioCube reviews
Overall, reviewers are very positive about the BioLite/BioCube fish tank, especially as a compact all-in-one aquarium for freshwater, saltwater, or starter reef setups. Owners praise its attractive design, quiet operation, built-in rear filtration, and upgraded LED lighting with sunrise/sunset and moonlight effects. Several reviewers say it looks great in a room, is easy to set up, and works well for small fish, plants, and beginner reef environments.
The main drawbacks are tied to its small size and all-in-one design. Users note that the back chambers can be cramped for maintenance, the lid can get in the way, and the lighting can encourage algae if left on too long. Some owners recommend upgrades such as a better media basket, skimmer, heater, sponge intake cover, or auto top-off system. There are also occasional reliability complaints around pumps, filters, or lights, though many reviewers still say they would buy it again.
