The 10 Best Fish Tanks in the UK

1. Tetra Aquarium Starter Line Tank – Best Overall

The Tetra Aquarium Starter Line Tank is our pick for the best overall fish tank. The 54-litre size is an ideal way to begin this hobby. The kit also includes a filter with cartridges, a light, and heater. Purchase a water conditioner, gravel, and decor to get ready to add your fish. The tank is well-made and built to last. It’s a brilliant value for the price.

The kit looks great, with everything fitting in with the theme. We can see it as a fun gift for a child just starting out and wanting to get up and running fast.

2. Diversa Aquarium – Best Value

The Diversa Aquarium earned high marks for the best fish tank for the money. If you just want a tank, this one is worth a look. It comes in a wide variety of sizes to get the right one for your space. The product comes with a mat to protect the bottom of the glass. It’s well-made with relatively thick sides and double silicone joints. Our only gripe is the black border, which we thought was distracting.

The price is affordable, especially if you want to build your aquarium with your picks for the other essentials. We liked that you have a decent selection of sizes.

3. Aqua One Oak Fish Tank – Premium Choice

The Aqua One Oak Fish Tank isn’t for everyone, if just for the price. However, it’s more than an aquarium. It’s a piece of high-quality furniture. The oak cabinet is convenient, with four drawers and four cabinets for storing your supplies. The package also includes a heater, canister filter, and LED light. All have specs that are appropriate for the size of the tank.

The accessories are of decent quality, although the filter is not the best choice because of the availability of replacement cartridges.

4. Aqua Ciano 60 Aquarium with the Stand

The Aqua Ciano 60 Aquarium with Stand takes the concept of a kit one step further by throwing in a stand. There’s also a heater, siphon, and LED light to complete the package. Everything is colour-coordinated in this modern style piece. This kit is ideal for beginners who want the essentials in one purchase. The two-part piece is the proverbial double-edged sword if it doesn’t fit with your decor.

It’s worth noting that Amazon can’t deliver this tank setup outside of the UK Mainland. The LED light is energy-efficient. The hood has a feeding hatch, which we like to see with these products.

5. All Pond Solutions Clear Glass Aquarium

The All Pond Solutions Clear Glass Aquarium is another barebones option if you only want a tank and not all the other goodies. The standout feature is its thicker walls of all sizes. It’s more than we typically see in these products. As you may expect, it’s heavier as a result. That can make larger sizes more challenging to move. The edges are braceless and rimless, giving an unobstructed view.

The construction left some silicone residue, which you’ll have to clean up if you’re the fussy type. While the view is clear, the excess is distracting.

6. biOrb Tube Aquarium

The biOrb Tube Aquarium is probably a fitting name for this fish tank. That describes its unusual shape. While it’s not the best choice for the fish, it is a space saver that gives viewers a 360-degree view. It’s the only acrylic product on our list. The shape is one of the advantages of this material since you can get a fish tank in any form you’d like because of its workability.

The tank includes the accessories you typically see with kit products, including the light heater and filter. As a decorative piece, it scores full marks. The low surface area makes it a choice for a few fish that use multiple layers in an aquarium.

7. Marineland Aquarium Kit

The Marineland Aquarium Kit has many features that you’d expect in a decorative product, starting with the lighting. It has both day and night LEDs to match the mood with the time of the day. The product is well-designed with a beautiful display that hides the business end of the tank. You just get to enjoy the fish and plants. The filter is more than we’d expect with this type of tank. That’s a good thing for your fish.

This aquarium is a decent choice if you just want to keep a couple of goldfish or a betta. The setup is more than adequate to support the conditions healthy for your pets.

8. allpondsolutions Nano Tropical Fish Tank

The allpondsolutions Nano Tropical Fish Tank is a brilliant choice if you want a complete setup at an affordable price. The design is attractive, with the curved sides adding a nice touch. It has both a mechanical and biological filter for optimal water quality. There’s also an LED light that has a pleasing glow. The hood includes a small feeding hatch to minimise evaporation loss and keep the fish inside the tank.

The product comes in several colours to match the tank with the room. It’s an excellent feature when you combine it with its shape.

9. Superfish Start 30 Aquarium Tropical

The Superfish Start 30 Aquarium Tropical takes the start package one step further with more accessories than you usually see in these products. You have the usual add-ons, such as filter and heater. This one adds a thermometer, water conditioner, and a net. Granted, that the latter is rubbish, but it will suffice. The other gripe is that the construction of the hood is proprietary, making a replacement hard to find.

On a positive note, we liked that the product includes 50% recycled materials, making it an eco-friendly purchase. Its primary purpose is for a starter setup for someone new to the hobby.

10. Fluval Flex Curved Glass Fish Tank

The Fluval Flex Curved Glass Fish Tank is more of a novelty than anything else. Its shape tells you that much. It’s rectangular but higher than it is wide. That compromises the surface area available for gas exchange. The appearance is interesting, with a bowed-out front that brings the aquarium experience closer to you. It includes a biological filter to keep the water within healthy parameters, although the water flow is swift.

It’s a decent value for the money. The light is adjustable with different brightness levels and colours to fit the theme of your decor. The setup does an excellent job of keeping the mechanical stuff hidden.

Buyer’s Guide: Selecting the Best Fish Tank

Buying an aquarium takes some thought not only because of the money but also its role in other aspects of the hobby. It can determine what fish you can get, where you’ll be able to put it, and how much maintenance you’ll need to do. It’s also a purchase that you only want to make once. Swapping out a new one is a daunting task, to say the least.

Therefore, it’s best to think about your choice carefully. Things you should consider include:

Tank Size and Shape

What size tank you should get is the most important decision you’ll make. We suggest avoiding getting one less than 34 L unless you’re just going to get a few fish.  It’ll limit the number you can get and increase your maintenance. However, consider the space where you want to put it. You’ll need access to the aquarium, both front and back. Of course, you want to put it someplace where you can enjoy it, too.

Size comes into play with the shape. A rectangular tank is ideal because it maximizes the amount of surface area for oxygen exchange. Square or odd-shaped aquariums are often lacking in this regard. Again, it falls back onto the health of your fish and the maintenance. However, keep in mind that a bigger tank means everything else is going to cost more.

Material

The two primary materials that you’ll see are glass and acrylic. The advantages of the former are that it’s resistant to scratching and is generally more affordable. The latter is lighter and comes in various shapes. However, these tanks can scratch easily and will cost you more. That makes glass the better choice since it’ll keep its clarity for its lifetime.

On the downside, glass is heavy, which will play a role in our next topic. It can also chip or crack if you’re not careful. That’s a problem because the damage becomes a weak point. If it happens, you’ll have to replace the tank. Otherwise, it will eventually leak or break.

Weight

Weight comes to the forefront when considering where to place your tank. There’s its weight plus that of the substrate, heater, filter, and most importantly, the water. That 34-litre aquarium will hold about 34 kg. It can easily tip the scales at 50 kg when you’ve filled it up with the other stuff. That’s a critical consideration when it comes to the location.

There isn’t a definitive formula for the number of fish per litre or imperial gallon. Too many variables can affect a healthy or unhealthy living environment, such as the fish’s metabolism, adult size, and water quality requirements.

However, it still boils down to the size of the space where you want to put it. Questions about what species to get can come later. For now, have an idea whether you want a tropical community tank, cichlid setup, or saltwater reef aquarium.

Placement

Another critical aspect of the tank’s placement is access to electricity. You should also put it someplace out of drafts and away from heating/cooling registers. Remember that most fish prefer at least 12 hours of light every day. That can affect whether you’ll place your tank in a home office or bedroom.
