Do aquariums need lids or covers?

If you’re a fish person or are thinking of getting an aquarium, you may be wondering if your tank should have a lid or not. It may seem a very easy question but the answer you give here can greatly affect the health of your fish, the maintenance of your tank and the look of your home. In this article we will cover various aspects of aquarium lids and covers and help you determine what is best suited for your setup.

Why Consider a Lid for Your Aquarium?

Many fish enthusiasts prefer using an aquarium cover or lid. Let’s look at the main reasons why you may want to use one:

Using a lid is a great way to prevent fish jumping out of the tank which is one of the best reasons. Many species, especially bettas and some cichid types, are famous for escaping their tank. When closed, a lid is a barrier that protects them.
Help Reduce Evaporation The water evaporation is a natural process which will cause you your valuable water loss. Utilizing a lid prevents evaporation of water thus maintains water level and top-offs. You will need to top-off lesser if you use a lid.
Having a lid is also essential in preventing unwanted debris, dust and pests from entering your aquarium. Whether it be dog or cat hair and dust bunnies or an unwanted insect, you can be rest assured that a cover will keep your tank clean and less the chances of introducing harmful contaminants.
It is essential in maintaining tropical fish temperature. A lid helps to keep the water temperature as it does not lose steam, when fluctuating temperatures occur.

Aquarium lids are essential. Moreover, they offer protection of your fish as well as preventing other animals from accessing the tank. There are pros and cons of each type so understanding that will help you decide.

Your fish will be in full view with glass lids. It also helps in retaining temperature. Thus, it has become popular. While they are quite rugged, they can break easily if you are not careful.
Acrylic Lids are preferred over glass lids, they are not heavy and don’t break. Cutting and customizing them for any fish tank set up is simpler. Though these alternatives may be less scratch-resistant than glass, they stay clear for far longer.
Mesh lids allow light penetration, ventilation and prevent jumping of your aquatic pets. Although they are good for a planted tank they may not suit all species including those who prefer a more confinement.
Hinged lids, made of glass or acrylic allow for easy access to the aquarium. Fish tank lids are especially handy for feeding and maintenance, but they don’t always offer a tight seal against evaporation.

Do some fish types require lids?

Always keep in mind the requirements of the fish before deciding to keep it. Here are some common examples:

Betta Fish: Bettas are famous for their jumping ability and will hop out of any opening possible. A lid is crucial for keeping them safe and contained. Also, as they prefer warm waters, it is better to put a lid on them.
Many cichlid species can jump out of their tank, just like bettas, especially when scared. A lid can help keep them in and water quality up by limiting evaporation.
Fish such as guppies are unlikely to jump like bettas or cichlids. However, lids help keep a tank clean and minimize evaporation. Furthermore, if you have a mixed-species tank, it keeps any small fish from being gobbled up by larger fish.

Benefits of Not Using a Lid

Even though a lid has tons of advantages, aquarium lovers choose to leave their tanks open. Here are a few benefits of open-top aquariums:

A design that is more appealing. An open top tank creates a more natural look that allows easy viewing. It can improve the beauty of your home or office overall.
When there’s no lid for the fish tank, gas exchange process is better, and oxygen is dissolved in the water. Heavily planted tanks can consume an abundance of oxygen which can be an added benefit.
With no lid, it is easier to access the tank for cleaning, feeding, and maintaining. You won’t need to remove the glass or acrylic cover to access your plants or fish.

Things to consider for aquarists

Whether or not you decide to implement a lid ultimately comes down to your own aquarium setup and the type of fish you keep. There are a few things to consider:

Lid Size: Smaller tanks may require lids more than larger tanks, because smaller amounts of water evaporate quicker. In smaller cages, fish may jump more often. When you use a strong lighting for the planted tank, putting a lid can diffuse the lighting and reduce the chances of algae growth. If you have a low-light setup, an open top can be better.
Think about the temperature and humidity in the room where your aquarium is located. If the area is warm or dry, a lid will keep your fish more level.

Conclusion

Whether your aquarium needs a lid or cover, in conclusion, is very much dependent on the type of fish you plan to keep, the size of your tank and your preferences. Though lids do have numerous advantages like preventing escapes and minimizing evaporation, while also keeping your tank clean, there are certain benefits associated with leaving your tank open. In the end, what will produce the most beautiful and healthiest environment for your aquatic pets should drive your decision making.
