Bottom Line

The perfect size for the beginning aquarist, this sturdy tank comes with lots of supplies, and is big enough to hold a small school of fish.

Pros

The 20-gallon glass tank comes with natural-daylight LED lighting incorporated into the tank hood, Marina Slim filter, water conditioner, Cycle Biological Supplement, a small pack of fish food, net, and guide to aquarium care. Add gravel, decorations, and a heater if you want to keep tropical fish.

Cons

Bottom Line

Small enough to sit on a desk or dresser, but large enough to hold a few fish, this kit makes it easy to start keeping pet fish.

Pros

You'll get a 5-gallon etched-glass tank with aluminum trim, tank hood with LED lighting system, and BioMax bio ring filter system. You'll need to add decorations, gravel, water conditioner, and fish care items, along with a few small fish.

Cons

No heater is included, so unless you plan on keeping goldfish or Bettas in the tank, you'll need to add one.

Bottom Line

The upright shape of this aquarium is perfect for a countertop or small table. A good choice for Betta fish, goldfish, or a few small tropical fish.

Pros

An attractive 5-gallon curved glass tank with Marineland's 3-stage hidden filtration system, and LED lights in both blue and white. Turn on the white lights for a daytime effect, the blue lights for a moonlit glow. Decorate with gravel, plants, and fish. Add a heater for tropicals.

Cons

The filter housing is difficult to clean. Some owners said the lighting was faulty.

Bottom Line

A mini-tank for showing off a Betta fish or a couple of goldfish or small tropical fish. A nice choice for a child's room.

Pros

Clear plastic 3-gallon tank resists shattering and cracks. Includes a pedestal base, Whisper filter and accessories, and LED light fixture. Add decorations, gravel, heater, water conditioner, and fish.

Cons

Only large enough for a couple of fish. Several owners felt the filter was not powerful enough to cycle the water.

Fish cannot prosper without a healthy habitat, which is what makes a clean and suitable tank so important. Keeping fish as pets requires a tank that is adequate in size depending on the species and number of fish housed within it. The size and shape of tanks also helps to determine the ability to maintain the correct water temperature and prevents problems such as stunted fish growth and even the untimely death of these exotic pets. Do your research before you buy to ensure you’re selecting the perfect tank for your fish.
