Acrylic Fish Tank or Glass Fish Tank? The Pros and Cons of Each

When you look at the big picture, deciding between a glass fish tank or acrylic fish tank isn’t the most critical choice. At the same time, knowing the pros and cons of each can help you maintain the tank more efficiently, and there may also be a difference in appearance in the long run.

Pros and Cons of Acrylic Fish Tanks

The type of livestock you have in your aquarium may make a difference between choosing an acrylic fish tank or a glass fish tank.1. An acrylic fish tank is significantly lighter than a glass tank, making it easier for you or your aquarium technician to move it if necessary. While this isn’t significant for small tanks, a larger tank can be difficult to move.

On the other hand: Glass tanks can hold more weight.

2. Wear and tear is only natural, but you can buff away scratches on an acrylic tank.

On the other hand: Over time, the wear and tear will inevitably become more prevalent. Additionally, essentially anything can scratch the tank, even the fish themselves.

3. Acrylic tanks are better for temperature control. It’s easier to maintain a consistent temperature inside the tank because acrylic serves as insulation of sorts.

There really is no downside here. This is a tremendous benefit, especially here in Arizona. You want to be able to control the temperature according to your requirements without having extraneous factors to consider.

Maintaining the ideal water temperature leads to a cleaner, healthier, and more comfortable environment for your livestock.

4. They’re strong and durable. They don’t break as easily, creating a safer environment for you and your livestock.

On the other hand: Glass is still stronger overall.

Pros and Cons of Glass Fish Tanks

Ask our aquarium maintenance technician about the differences between glass and acrylic fish tanks.

1. Glass fish tanks tend to be less pricey than acrylic tanks, likely due to their heaviness.

On the other hand: Because of the way light hits the tank and the water, you may be able to see the fish more accurately and more clearly with an acrylic tank.

2. The fish are no match for glass. Glass is less likely to get scratched inside or outside.

On the other hand: When a glass tank does have scratches, it’s more difficult to remove them. Additionally, glass tanks are more likely to completely shatter, endangering livestock and people and possibly damaging furniture.

Emergency services for aquariums are available for Seatech Aquariums clients.

3. Glass tanks are prettier. They look more natural and have a natural shimmer to them.

On the other hand: As mentioned above, acrylic tanks are better for temperature control. Glass itself does get warmer and colder. For this reason, if you do have a glass tank (or acrylic tank for that matter), you should keep it away from direct sunlight.

Types of Fish Food: What are the Differences?

Many fish are picky eaters. Some won’t eat certain types of fish food at all, while others are fine with almost anything you give them. It’s important to know the difference and give the fish what they want, mainly because you don’t want other fish in the tank to become fish food. And that can happen if you’re not careful.

Keep in mind that the type of fish food that will be best for your livestock will depend a variety of factors, including:

  • Whether they’re saltwater fish or freshwater fish
  • The specific fish breeds in the tank
  • Whether or not you have other types of animals in the tank, such as frogs or shrimp
  • The size, temperament, and natural habitat of the fish

Basic Types of Fish Food

There are a few basic categories of fish food: flake food, live food, freeze-dried, frozen, spirulina/seaweed, and some types of greens and other produce.

Flake Fish Food

Flake foods are the easiest for humans to work with, are relatively inexpensive, and provide fish with some of the nutrients they need. Many fish don’t prefer flake food, but it’s a viable option. If you have large, hardy fish, you may want to think of flake food as doggy snacks.

When choosing flake food, read the ingredients, as much of them contain fillers that don’t provide fish with as much nutrition as they would obtain from more substantial foods.

Remember that flake foods expire, which means they won’t have much nutritional value at all after a while.

Flake foods are easy options for aquarium owners.

Freeze-Dried Food

The benefits of freeze-dried fish food is that it is easy to use and has a longer shelf life than some other options. The livestock tend to enjoy it as well, depending on the breed. The downside is that the nutritional value is lower than that of live or frozen food.

Bloodworms, shrimp, anchovies, daphnia, and plankton are among freeze-dried options.

Frozen Fish Food

Frozen fish food is perhaps the most popular option among hobbyists. The animals enjoy it, and it maintains most of its nutritional value. It can also generally keep in the freezer for approximately six months.

The downside is that some have preservatives, so they may need to be rinsed before they are given to the fish; otherwise, you would be introducing these contaminants to the ecosystem.  There is some controversy here as well: some hobbyists say frozen fish food leads to higher waste and nitrate levels, while others say they see the opposite results.

Another downside is that frozen fish food isn’t as readily available as freeze-dried food, flakes, or pellets. You will need to go to a pet supply store or order it from your aquarium maintenance technician.

Common types of frozen fish food include mysis shrimp, crab, bloodworms, and daphnia.

Live Fish Food

Some fish won’t touch the flakes, frozen foods, or dried foods unless it’s a matter of life or death. Live fish food may be the hardest for hobbyists to work with, although live fish food may be the most natural and substantial for the fish.

However, there is some controversy regarding how healthy they actually are for the animals in the tank, especially considering that the live food itself may have bacteria.

If that’s your preference and what’s most ideal for the animals in your fish tank, some commonly used types of live fish food include:

  • Some types of shrimp
  • Daphnia (water fleas)
  • White worms, earthworms, grindal worms, and microworms
  • Fly and mosquito larvae
  • Flightless fruit flies
  • Vinegar eels


Spirulina, which is basically algae or seaweed, provides tremendous nutritional value, although it’s not as satisfying to the livestock. It’s more like a healthy side of broccoli to complement a steak. Spirulina is known to have antibiotic properties, enhance pigmentation, and assist in healthy growth. It’s available in powder form or as flakes or pellets.

Fruits, Vegetables, and Plants

Every now and then as a treat, you can add a leaf of lettuce to the tank, which also may be effective in ridding the tank of nuisance snails. A slice of cucumber or zucchini will bring joy to the tank as well.

If you add such items to the tank occasionally, it’s critical that you clean these fruits or vegetables with RODI water first in order to get rid of the pesticides, dirt, and other harmful contaminants. For leafy vegetables, dip them into the water and gently rub them to clean them. Allow the leafy vegetable to dry before placing it in the tank.

Adding a leaf lettuce to a fish tank can help you get rid of nuisance snails.

Creating a Fish Feeding Routine

One more thing we want to stress is how important it is to feed your fish only the adequate amount of food. While it’s important to feed fish on a schedule to ensure they don’t become hostile or sick, it’s also critical that you don’t feed them too much. Giving fish too much food means more waste in the tank. When you have too much waste in the aquarium, the manmade and natural filters won’t keep up, and a dirty tank can sicken fish.

Determining the best types of fish food for your aquarium can be complicated, but we’re here to help. We can help identify the most ideal foods and treats for your fish tank, as well as suggest an appropriate feeding schedule.
