As a loving fish parent, you know that a great aquatic home is one of the most important factors when it comes to your betta’s health and happiness. You want to know if the Fluval Spec Aquarium Kit could be the dream home your little betta darling deserves.

You’ve come to the right place. We’ve done all the work and hours of research for you to help you make an informed decision. Read on and we’ll give you all you need to know about this aquarium kit and whether or not it’s right for you.

4 Things That Make the Fluval Spec (5 gallons) a Great Betta Fish Tank

1. Enough Space for Horizontal Swimming

Size: 5 gallons

Dimensions: L x W x H: 20.5 x 7.5 x 11.6 in (52 x 19 x 29.5 cm)

The entire kit includes a glass fish tank, a filter system, filter media, a plastic lid and LED lights.

This aquarium kit is a champion when it comes to providing a comfortable, beautiful and cozy home for your betta fish. It holds 5 gallons of water which is great for a single betta fish. You can choose between a black or white version.

The aquarium has a modern and stylish design. It’s made of etched glass with aluminum trims. One big advantage is that it gives bettas enough space to swim horizontally because of its long shape. Nevertheless, it takes up little space and fits easily on narrow countertops or tables.

2. The Adjustable Filter Is Great for Bettas

The Fluval Spec features a quiet and highly effective filter with 3-stage mechanical, chemical and biological filtration. The filter flow can be adjusted which is ideal for betta fish since they usually prefer a gentle flow.

The filter sits in a built-in filter compartment at one side of the aquarium. This compartment blends in easily without being obtrusive and only takes a little away from your view.

If you need to add a heater for your betta, you can put a small and thin one inside the filter compartment.

3. Bright Lights Illuminate Your Betta Paradise

This fish tank has an overhanging light system that contains energy-efficient LED lamps with a light range of 7000K. The light bar sits on top of the aquarium and has a waterproof casing.

You can set the lighting to white or blue light. The lights are bright enough to put your beautiful finny friend into the spotlight, enhance their colors and promote plant growth.

4. A Lid to Protect Your Betta Fish

Included in this aquarium kit is a plastic lid with a long and thin opening in the middle. The lid is transparent and offers your betta protection from outside disturbances. It’s also an important feature to keep your finny friend safe inside their wet home.

How Is the Large Fluval Spec Model (16 Gallons) Different?

Size: 16 gallons

Dimensions: L x W x H: 21.8 x 11.5 x 17.5 in (55.5 x 29 x 44 cm)

The entire kit includes a glass fish tank, a filter system, filter media and a plastic lid with integrated LED lights.

The 5-gallon model is great for one betta but if you have more space and prefer a large aquarium, the Fluval Spec is also available with a capacity of 16 gallons.

With this fish tank, you can create a truly luxurious aquatic paradise. The 16-gallon Fluval Spec model isn’t just an enlarged version of the 5-gallon model. It has a couple of different features.

These are the features that differentiate the 16-gallon model

  • The lights are directly integrated into the lid.
  • The lid is made of black plastic.
  • The part of the lid covering the filter compartment can be taken off separately for easy access.
  • The glass aquarium doesn’t have aluminum trims.
  • A honeycomb pattern around the top of the aquarium and the filter compartment camouflages the waterline and the compartment.
  • The filter has adjustable twin output nozzles.
  • The direction of the filter flow can be adjusted.

What Else to Know About the Fluval Spec Aquarium Kit?

A 2.6-gallon Fluval Spec model is also available. Its features are the same as the 5-gallon model. But we wouldn’t recommend it for betta fish, as it’s too small.

The main drawback of the 5-gallon model is that the overhanging light bar doesn’t have hinges. It’s rigid and can’t be flipped back for easy access to the tank.

This means that whenever you need full access to your aquarium for maintenance or cleaning, you have to take off the light bar. Also, when you feed your fish, you have to reach in between the opening in the middle of the lid and the light bar above the lid.

Despite this, the aquarium is easy to clean and maintain. The lack of hinges on the light bar is only a minor nuisance.

Another issue worth mentioning is that the filter flow might still be a bit too strong for some bettas. In this case, a pre-filter sponge should be helpful.

Preciously Verdict

The Fluval Spec is for you if you want to get the best fish tank for your betta. It’s a good-quality, well-designed aquarium with a contemporary, clean look. It doesn’t need much space and is perfect for giving your little betta darling a beautiful, comfortable and cozy home. It’s also easy to clean and maintain.

The 5-gallon model is ideal for small countertops or tables. The long shape gives betta fish plenty of room to explore, play and hide. It also enables them to swim horizontally. It offers an ideal home for your finny friend and comes at a price that’s in the middle range among comparable aquariums.

Its main week spot is the rigid light bar on top of the aquarium that isn’t hinged and can’t be flipped back. But that’s definitely not a deal-breaker and the advantages of this aquarium kit clearly outweigh the drawbacks.

If you want the advantages of the Fluval Spec at a larger size, you should go with the 16-gallon model. It also has all the great features of the 5-gallon model. The main difference is that the larger model has lights which are directly integrated into the lid.
