Incredible Features Of This Aquarium

Futuristic LED Hood

One thing you cannot say about the Tetra 20 gallon fish tank is that it’s not stunning.

The slim, stylish, color fusion LED hood plays a huge role in this. It creates a gorgeous shimmer effect on the water, making the aquarium look alive and unique.

You can choose to let the LED lights run through the color cycle or set a specific color.

One other thing to note is that the LED hood utilizes energy-saving bulbs.

Besides lowering your monthly power consumption, this also ensures that you’ll never have to replace a light bulb again.

Quiet Tetra® Whisper Filter

If this is your first attempt at keeping fish, then you probably don’t know that aquarium filters can be annoying to deal with.

Some filters are noisy, others are poorly made, but Tetra’s ® exclusive Whisper Filter is none of those things. It is as quiet as it is powerful, but if pressed to pick one thing to love about this filter, it is exceptionally quiet in doing it's job.

Realistic Plants and Artificial Décor

Along with the filter and a UL heater, this 20-gallon fish tank also comes with artificial décor in the form of two Wonderland plant multi-packs and a blooming white anemone.

This gives the aquarium a nice undersea vibe and provides a hiding spot for fish to keep them from getting stressed out. The plants sway naturally with the filter’s current to create a realistic underwater environment for the fish.

Also included in the artificial plant's package is a small but effective boxwood plant.

Comprehensive Beginners Kit

To recap, the Tetra 20 Gallon fish tank is a great choice because it comes with everything you need to start an aquarium.

In the box, expect to find the tank (a little assembly is required), ColorFusion LED lights, a Tetra® Whisper Filter plus filter bag, a UL heater, some fish flakes, one dose of Tetra  SafeStart, a small net, a thermometer, two plant multi-packs, a small boxwood plant, and a blooming white sea anemone. 

Next, simply add your choice of gravel and water ( wait until the ammonia cycle completes ) then when the water conditions are optimal - add your tropical fish!
