Aquarium hoods are more than just a decorative part of the tank and serve several different purposes. Anybody who has owned an aquarium will know that many fish species tend to jump out of the tank and end up on the floor surprisingly often. That in itself is a good reason to buy a hood to secure the top of the tank; however, the fish also need to be protected from curious pets or children and falling objects. A well-designed hood has the following features:
- Strong but lightweight build
- Wide feeding portal
- Mounting brackets for light bulbs inside with splash guard
- Openings for air hoses
- Good looks that complement most general aquarium set up
- Vents for heat and air
Hoods also act as regulators for evaporation and temperature inside the tank, without which the water level falls frequently, making the room humid and creating the need to top up the tank frequently.
Finally, several hood manufacturers offer their hoods with an inbuilt LED light that works well with most tanks; however, when you are growing different types of aquatic plants, you would need a hood that can offer to mount for extra lighting.
Before you get to choose a hood, it’s essential to know the most common sizes and dimensions of aquarium tanks.

The center segment has room for a single T8 fluorescent lamp and can be separated from the hood. The rear part features a cut-out for filters and air hoses.
- Dimensions: 20 x 8.6 x 3.4 inches

1. All Glass Strip Light 30 Inch aquarium hood
This 30-inch fluorescent strip is designed primarily to be used with the Aqueon Versa Top hinged glass aquarium hood or a replacement strip for full hoods.

This 30-inch strip light works beautifully well with my retrofitted old tank’s lid.

I overcame the issue with a Plexi-glass panel that seals the tube in.

Aqueon’s deluxe full hoods are popular for their classic design and simple features that do the job of a great aquarium hood without any redundant additions.

The clear vinyl back strip is tough but easy to cut into any size desired to accommodate other tank equipment like filters, tubing, and heaters. The canopy is see-through and can take any external lighting.
- Dimensions: 48 x 11.5 x 1 inches
- Weight: 5.5 pounds
- Clear, very low profile canopy
- The customizable vinyl back panel
- Tough tempered glass
- No included lights with the unit
The canopy comes in 2 separate equal-sized pieces, which can be set up easily. I had to cut the vinyl back panel with a hack saw according to the outline of my filter, which went quite smoothly. Since I wasn’t comfortable with the handles stuck with double-sided tape, I used a bit of epoxy to secure them to the glass.
75-gallon Aquarium Hood

The glass on this canopy is thin enough to support its weight but not thick enough to be too heavy, and when handled well, it is quite durable. What I like the most is the hinge joint is about a third of the way from the front end and doesn’t block any light strip placed over the center.
