Our take on the Tetra Aquarium, 20 Gallon, Complete Tropical Fish Tank Kit With LED Lighting And Decor For Freshwater Fish

The Tetra 20 Gallon Complete Kit bundles a glass tank, hinged LED hood, Whisper PF20 power filter, heater, thermometer, water conditioner and food samples, plus artificial plants. It is aimed at beginners who want one box instead of piecing a freshwater setup together. The 24 x 12 x 16 inch footprint fits on a sturdy stand and leaves room for a small community of fish. Against bare tanks or kits with only a filter, it covers heating and lighting too, though the filter and heater are basic units that experienced keepers often upgrade.

About the Tetra Aquarium, 20 Gallon, Complete Tropical Fish Tank Kit With LED Lighting And Decor For Freshwater Fish

The Tetra Complete LED Aquarium Kit is a 20-gallon glass aquarium set up for freshwater fish. It comes with the lighting, filtration, heating and decor needed to start a tank. Gravel and fish are added separately.

A low-profile, hinged hood holds the energy-efficient LED lighting system, which gives a natural daylight effect. The Tetra Whisper PF20 Power Filter uses a Tetra Whisper Bio-Bag Filter Cartridge. It filters mechanically to catch debris and chemically with Ultra-Activated Carbon to remove odors, discoloration and toxins.

Artificial plants add a natural ocean look. A setup and maintenance guide is included. Children under age 13 should have adult supervision with setup, maintenance and fish care.

Small community fish such as tetras, rasboras, guppies or a single betta work well. Ask your retailer about stocking levels and avoid large or aggressive species.
