7 Top-Rated 5-Gallon Fish Tank Kits To Buy 2021 Review
1 Marina LED Aquarium Kit
This 5-gallon tank from Marina is made from glass. It’s rectangular in shape with visible black silicone sealing the corner edges. On top is a small black hood with a matching black base underneath.
With the tank, you’ll get a Marina Slim S10 filter. It clips onto the side of the tank and filters water using cartridges. Spare filtration cartridges are available to help you keep it maintained at home.
In the hood, there’s a built-in LED light setup. This light is made to resemble natural daylight. It’s not made for coral reefs, but it works well for freshwater plants and for viewing your tank.
As a bonus, this kit includes other accessories to help you get started immediately. There is a packet of Fluval Max fish food, Fluval Aqua Plus water conditioner, Fluval Cycle biological supplement, and a small mesh net. You’ll get an instruction manual to basic fish care and aquarium maintenance.
This is a good starting point for a basic freshwater tank. The filter and light included with the kit give you options for what you want to put in the tank, including plants and fish. You’re unlikely to have to add much to this kit to get a good start.

2 Fluval Spec V Aquarium Kit
The Fluval Spec V aquarium kit is a small rectangular tank with a built-in sump section on the side. The sump consists of a filter and a small space for a heater or other accessories. The sump side is black or white, along with the base, while the cover and seams are transparent.
An LED light rack floats above the tank cover. The system includes 37 LEDs for bright high-output lights at 7000K. Plants and fish thrive under this light, though it’s not meant for coral reefs or live rocks.
For filtration, the filter is built into the side sump of the tank. There is a 3-stage filtration system that includes mechanical, biological, and chemical filtration media. Covering the filter, a beautiful honeycomb pattern is etched into the glass so it won’t ruin the aesthetic of the tank overall.
This kit comes with the tank, filter components, filtration media, the cover, a low-voltage transformer, the LED lights, and a circulation pump for the filter.
For a bit more style in your freshwater tank, this is a good choice. It looks modern and sleek, especially with the filter and other components obscured from sight.
Nothing can be perfect, so let’s look at this from both sides…
3 Penn Plax Curved Corner Glass Aquarium Kit
Viewable from all sides, the Penn Plax curved corner aquarium has lovely rounded edges on all four sides. It’s rectangular in shape and made from glass. The edges are sealed with transparent silicone for a sleeker look.

Filtration in this tank comes from the included Cascade internal filtration system. The filter sits just inside the tank and keeps the water clear. It operates using cartridges.
In total, this kit includes the rounded glass tank, filter, LED light, a base mat, and the plastic lid.
Anyone looking for a more panoramic view of their tank will enjoy this aquarium kit. The view is great from all sides and the tank is well-built for easy viewing.

4 MarineLand 5 Gallon Portrait Glass Aquarium Kit
As a uniquely shaped option, this MarineLand portrait aquarium is a tall glass tank. It sits on top of a black base with a black built-in filtration area in the back. The front corners of the glass tank are seamless and round.
For filtration, the built-in back sump filter provides all 3 stages of filtration. There’s a filter pump as well that keeps up the water circulation and flow within the tank. All of these components neatly hide out of sight.
To cover the top, a sliding glass top is included with the tank. Hanging above that from a hinged arm, an LED light sits over top the tank. The light can switch between bright white and soft blue moonlight glow.
Another sleek, modern aquarium kit, this is a good choice for anyone with a taller, skinnier place to fill. You can easily keep it in most homes or offices without taking up too much space.

5 Fluval Edge Aquarium
If you’re looking to make a more enclosed aquarium environment, this tank from Fluval is a simple choice. It’s a 6-sided enclosed tank with only a small opening at the top. That opening has a cover that connects to the filtration sump area on the back of the tank.
This tank is actually 6 gallons, excluding the water taken in by the filter column. All three stages of filtration happen in the back. The lighting also hides inside the decorative column.
For lighting, the included fixture is made up of white and blue 7600K LEDs. The light sits overtop the tank and shines through the opening. A small cover sits on top over the light and opening.
Unlike most tanks, the top of this tank is also sealed closed with only a small opening in the center back of the tank. It provides a very unique viewing experience from all angles around the tank.
If you want your tank to be the centerpiece of a room or to be a statement piece, this is a fantastic choice.

6 Tetra Crescent Acrylic Aquarium
The Tetra Crescent is an acrylic tank shaped close to an oval. Edges are all nearly seamless with only slight distortion. On top, a low-profile plastic lid keeps the tank enclosed.
With this kit, you’ll get a filter, filtration media, the tank itself, the cover, and an LED light setup. The light system is made up of 16 LEDs that can be turned on to be bright white or blue. Combined with the shape of the tank, the lighting works to create a great view from all angles.
The Whisper internal filtration system works using filter cartridges full of media. You will get all three stages of filtration and can replace the cartridges as needed for easy maintenance.
This acrylic tank is a nice option if you want a sturdier material with a rounder shape. Because it’s more transparent around the edges, it makes a great ornament for the living room or your office.
Here’s the real scoop on this tank…
7 GloFish 5 Gallon Crescent Aquarium Kit
Similar to the Tetra Crescent, the GloFish 5 tank is a curved acrylic tank. The edges are virtually seamless, making it easy to see your fish and tank inhabitants from all angles. A black plastic lid covers the top.
With the aquarium kit, you’ll get an external filter that sits on the back of the tank. It’s a low-flow filter that won’t disturb bettas or other fish that prefer calm waters.
The LEDs shining into the tank are a vibrant blue. This gives your fish, plants, and decorations a fun glow while the light is on. You can turn it on and off with a switch.
This is a fun tank for kids. They’ll enjoy the blue light, glowing neon rocks, and the smaller size. It’s a good beginner fish tank for freshwater fish.
