The debate over whether fish tanks should have a cover or not continues today. Some enthusiasts believe a lid is essential for both marine and freshwater tanks, while others love the beautiful look of topless aquariums.
Beyond that, the terms aquarium lid, hood, and canopy often get people confused because they think they are one in the same. In reality, all three items serve different purposes for your fish tank.
So when you set up a 55 gallon fish tank, should you get a cover? Which type does your aquarium need, and is it time to ditch the store-bought canopy and build your own custom setup?
The Debate Over Topless and with Cover
You might be surprised to hear that people are debating whether or not it’s a good idea to cover aquariums, but this has been an ongoing controversy for some time.
Below I have outlined the key advantages of having a cover and going topless in the following points:
Covered | Topless |
---|---|
– Keeps jumpers from carpet surfing. – Reduces water evaporation, especially for a saltwater aquarium. – Has a barrier between the lighting and the water, which is helpful for cleanliness. – Preventing the salt from creeping into the light fixtures. – Pets and children safe – Preventing contaminants – Reduces noise levels. – Prevents fish from jumping out of. – Provides a place to put some equipment. | – Aesthetics – Better for gas exchange – Better for lighting – Easier access – Easy to maintain |
55 Gallon Tank Lid & Hood Dimensions
Standard 55 gallon fish tank dimensions are 48″ (L) x 13″ (W) x 21″ (H) (122 cm x 33 cm x 53 cm). In most instances, you will need TWO 24″ (L) x 12″-13″(W) lids or hoods.
I heard that some companies sell full-length lids for 55-gallon fish tanks. But I wouldn’t risk this because of the cross brace on the tank unless you could confirm that it is just a “kit,” which includes two 24″ (L) x 12″-13″ (W) glass panels.
Aqueon(All Glass) and Marineland (Perfecto) (Lid) Hood
In the glass aquarium business, there are two largest players make 55-gallon aquariums, including:
- Spectrum brand groups [1]: Tetra, Marineland, Perfecto
- Central Garden and Pet brand groups [2]: Aqueon, All Glass
No matter which brand of glass aquarium you have, either Spectrum aquarium lines or Central Garden & Pet aquarium lines, be aware that the aquarium covers they offer will not be compatible with each other.
Another problem here is a big-box pet store often carries these tanks under their own store brand by covering up the true manufacturers, but if you look closely at the inspection labels or labels on the plastic light hoods, you can tell they are kit-branded.
If you have an Aqueon or All Glass aquarium (including rebranded) and try to put a Perfecto (or Marineland) cover – it won’t fit even though both two aquariums are standard dimensions.
How to Determine the Lid & Hood Dimensions?
Simply follow these easy instructions to find the correct dimensions:
Step 1: What Are the Dimensions and Brand of Your 55 gallon Fish Tank?
If you know the brand of your aquarium, the job is much easier. Some aquarium brands, such as Aqueon offer their own branded lids and hoods.
Step 2: Does Your Aquarium Has a Center Brace?
If you can’t find the brand or model number of your aquarium, don’t worry. The next step is to check if your aquarium has a center brace.
It is a horizontal bar that runs the length of the tank in the middle and is used to support the weight of the glass, which determines whether you need one or two lids/hoods.
Basically, 55-gallon fish tanks that have a center brace will need two lids or hoods.
Step 3: How to Measure Aquarium Opening?
If your aquarium has a center brace, measure the length from one inner edge of the tank to the inner edge of the center brace. Write this number down. Also, measure the width from the front inner edge to the back inner edge. Write this number down too.
If you have used or old 55-gallon aquariums from a garage sale that don’t have a center brace, you should consider adding one instead of looking for a full-length lid.
Type of Aquarium Cover
In pondering a cover for your 55 gallons fish tank, you may decide which type you need based on a few factors. The following table provides a comparison of the three main types.
Type of Cover | Pros | Cons |
---|---|---|
Glass Lids | – Most durable – Effective – Versatile – Easy to clean | – bit more expensive – Does not include lighting |
Hood | – Built-in lighting – Less expensive | – Does not fit tightly – Become brittle over time |
Canopy | – Stylish (Made of wood) – Comes with lights | – Expensive |
Once you come to grips with the pros and cons listed above, it’s time to choose a cover. And that decision will come down to two primary factors: size and budget.
55g Aquarium Glass Lid (Canopy)
As we mentioned earlier, the glass lid, or glass canopy, is by far the most durable and effective type of aquarium cover. But, it’s important to weigh the following downsides before making a decision.
First, a glass lid will reduce gas exchange at the surface, and in turn, excess CO2 builds up in the water column, causing low PH. This is why I recommend using a power filter to help with gas exchange in a 55-gallon aquarium.
Additionally, a glass lid on your aquarium creates a greenhouse effect [3] by trapping heat from your lighting, causing the water temperature to rise.
If you’re going to buy a glass lid, ensure it comes with a plastic strip on the back of the glass top, where you can cut cutouts for custom filters and other accessories with scissors or a utility knife.
Most commercial glass lids typically don’t include lighting. They have a simple design – two panes of glass connected in the middle with a dark plastic hinge. To illuminate your aquarium, you will need a compatible light fixture for the glass cover.

The manufacturer claims this lid is compatible with 55 gallon Marineland & Perfecto brands fish tanks and will NOT fit Aqueon or All Glass aquariums.
The clear hinge on this product is my favorite feature because it doesn’t obstruct light and cast shadows the way that Aqueon Versa Top’s dark plastic hinge does. But, customers have reported that the hinge is a bit stiff to start.
Perfecto Hinged Aquarium Canopy in Glass
[amazon box=”B006OOODAO”]Another glass canopy option for a Marineland or Perfecto 55-gallon aquarium, but at a low price. Don’t let the picture fool you, and this is a two-piece set, each with actual measurements of 23″ x 9.5″ (not including the vinyl strip on the back.)

55g Aquarium Hood
Aquarium hoods are popular because they usually house the aquarium light. In general, the combo is normally cheaper than buying a separate lid and lighting unit.
Don’t skimp on your aquarium lights when it comes to aquarium hoods. Inexpensive brands often have low-quality lights. Make sure to check the quality and specifications of the light fixture before making your purchase.
Also, if you’re not into do-it-yourself, be sure to buy a Marineland or Perfecto hood for Perfecto-Marineland” aquariums (this includes all rebranded products) and an Aqueon or All Glass hood for their company’s aquariums.
3 Commercial 55 gallon Fish Tank Hood
Aquarium hoods are not quite as popular as they used to be because of the numerous lighting options that have become available. That said, I have gathered 3 of the best options currently available.
MarineLand LED Light Hood for Aquariums

Aqueon LED Background Hood
[amazon box=”B00NRBBCK6″]This light is perfect for anyone who needs a hood light combination for an Aqueon or All Glass 55 gallon fish tank.
To help save you time on cleaning, the entire unit is easy to disassemble because the cover is separate from the light.
This unit also has three light settings: a daytime light, a blue nighttime light, and an off setting. You can change the mode by pushing the switch in different directions.
I was surprised by how high-quality and well-tailored the product is. You could even add a second light in the hood–it’s that roomy!

I love that the filter cutouts are perfect in size. Plus, there’s no extra open space where my cats could potentially drink from the tank.
55g Aquarium Canopy with Stand
In the trade, the word “canopy” is often used to refer to glass lids. But in the hobby, it is more commonly thought of as a decorative top that is often made of wood and matches the materials on the aquarium stand.
They cost more than the other two types. In some cases, they can even be more expensive than the aquarium. Of course, the high-end finish and built-in look remain unmatched.
If you want a custom stand and canopy, stop by your nearest local craft store or take the DIY route!
