Get The Best Saltwater Fish Tank From My 7 Picks To Start Your First Marine Aquarium

Starting a saltwater aquarium is exciting, but being honest, it’s a little expensive as well. In addition, you also need a bit of specialized knowledge because saltwater aquariums are totally different from freshwater aquariums.

The first thing you need to collect to begin the saltwater aquarium journey is a tank. You have two options; you can buy a tank where important gears like a filter and LED lights are attached to it. Or you can purchase only the tank, and then afterward you can arrange the necessary equipment separately.

When I was a beginner like you, I chose the first option and bought a starter kit that helped me to gain valuable experience. After that, when I had good enough learning, I made my own saltwater setup with a much bigger tank.

If you are like me and want to buy a starter kit only for you, I have made a list of the best saltwater fish tanks, which I found beginner-friendly and noteworthy. In summary:

Best Saltwater Fish Tanks (Ranging From 8-Gallon To 50-gallon)

I have kept aquariums ranging from 8 gallons to 50 gallons on this list of best saltwater fish tanks. Choices are diverse, and also budgets are not the same. The price considerably varies according to the size of the fish tank. Therefore, from the list, you can choose whatever matches your demand. 

Nevertheless, I always recommend a bigger tank because a large tank can give you much more flexibility. The water parameters in the tanks remain stable for a more extended period. You will also have more room for fish and coral. 

One of the best decisions you can make in your saltwater aquarium hobby is to invest in a larger tank. This will allow more room for fish and corals- but there are other benefits as well. Sometimes smaller tanks can be tough to keep maintaining the right balance.

I would recommend buying a bigger tank like the SeaClear acrylic 50-gallon aquarium. This acrylic-made aquarium is much more robust, lighter, less prone to breakage, and most importantly, provides a much clearer view than a glass aquarium.

The combo set comes with the fish tank, reflector, and 24 inch light fixture. Although some users mentioned, the light is a little underpowered. But swapping it with the more accurate or desired LED light fixture is not a big deal. 

Although it does not come with extra gadgets, like a filter, heater, skimmer, sometimes the gears packaged along with the kit do not serve the purpose for the user. So very often, you may need to put them aside and buy separate accessories to meet the demand. 

SeaClear acrylic aquarium is suitable for both freshwater and saltwater use. The colors in the aquarium fill up the room, and you will never get tired of looking at its beauty or watching fish swim happily. 

This fish tank starter kit offers a great opening for those looking to get started, but be aware that some things are left out of this package.


  • Bigger size aquarium
  • Acrylic made tank; much more transparent and lighter
  • The absence of edges makes it aesthetically pleasing
  • Comes with 24 inches LED light fixture


  • LED light is underpowered
  • A little expensive

The hinged top canopy design allows easy access to your fish or corals while providing a secure seal when closed. Additionally, the built-in, high-quality pump is quiet and reliable, so you can enjoy the soothing sound of your tank at night without being disturbed by noise.  

The Coralife Led Biocube Aquarium offers two different sizes. One is 16-gallon capacity, and the other one is 32 gallons. You can choose whatever you want, but I would always suggest bigger is better. Its compact, versatile filtration system; provides excellent three-stage filtration, and you can use your own preferred filter media if you want.

The kit does not include a heater, although the lights are warm to keep the tank temperature in a reasonable range. However, if you still need one, you can easily install one specially made for the saltwater tank; you need to buy it separately. 

I highly recommend this aquarium kit for anyone who wants to get into reef keeping but wants to keep things simple and low-cost.

JBJ’s Rimless Desktop Aquarium combines a sleek design with the convenience of an all-inclusive package that includes everything you need to start fresh in the saltwater aquarium hobby.

SCA 50 gallon Starfire glass aquarium is unique in design and probably the single best saltwater fish tank in the market. It uses the sump mechanism consisting of three chambers which are very well built and strong. 

All the tubing, bulkheads, filter media, return pipes are included to complete the sump setup. However, few users find it somewhat tricky while setting up the sump initially. But it’s not a big deal; with a bit of trial and error, you can easily do that.

The most significant selling point is the tank comes with a beautiful stand. The stand is sturdy enough to withstand the weight of a 50-gallon tank on top of it. The sump, along with all the tubing, will remain hidden inside the cabinet. You can also use the cabinet to store maintenance supplies. 

It’s not finished yet! When you buy the kit, you will also get a protein skimmer and water pump to circulate the water between the sum and the tank. Unfortunately, light is not included in the package, which is the only con of the kit. 

If you have large enough space or simply want to go for a bigger tank that is easier to maintain, this 50 gallon SCA Starfire glass aquarium is for you. The rimless tank is designed to give you total viewing pleasure without any distraction and to enjoy the saltwater hobby to its full value.

Factors To Consider While Choosing Saltwater Tanks  

Larger & Smaller Tank

Saltwater Tank - Larger Or Smaller

Selecting the right tank for your saltwater aquarium is the first step you’ll need to take in your new hobby. There are many different size aquariums, but smaller saltwater tanks can sometimes be tough to keep in balance. A tank of at least 20 gallons is a good size to start with, but the bigger the tank, the more you’ll be able to enjoy working with! 

A bigger tank has many advantages, such as lower nitrates/ammonia levels (they cycle much slower), clearer water with increased oxygenation capabilities. In addition, a large marine ecosystem can handle the daily water fluctuations better than a more miniature ecosystem.

Therefore, if you have the budget and space available, buy a large aquarium. Although, as always, you can start with any size aquarium but keep in mind the downside of a smaller one. 

Glass Or Acrylic

Saltwater Tank - Glass or acrylic

Another consideration while buying a tank is its material. Glass aquariums are ubiquitous and are one of the best because they are sturdy, robustand not susceptible to scratching. In addition, glass tanks don’t turn yellow over time or while exposed to sunlight. 

Class tanks are much heavier than acrylic tanks, which is why people nowadays opt for Acrylic ones. However, while you put the substrate and water inside, it doesn’t make a big difference. 

On the other hand, acrylic tanks are lighter, stronger, and much clearer than a glass aquarium. But the opposing sides are that acrylic tanks are much more expensive, easily get scratched, and can turn yellow with age. 

So, now you know the pros and cons of both glass and acrylic fish tanks, it’s your decision, but I always prefer glass tanks. 

Rimless Tank Or Regular Tank

Saltwater Tank - Rimless Or Regular

Rimless tanks give you an unobstructed view of your underwater world. They are gaining popularity because their aesthetic appeal is undeniable, and looks terrific. 

They are made of high purity, clearer thick glass, and silicone to support the weight. The glass contains low iron and frees off a green hue present in regular glass and an eyesore.   

Nano Reef tank lovers also love rimless aquariums. It is also pretty common in aquariums ranging from 25 to 200 gallons; however, beyond 200, it’s Not so common because of the increased cost and better strength is required. 

Advantages Of Pre-Equipped Aquarium Kits

Saltwater starter kits help you to get you started into the fishkeeping hobby, often in a less expensive way. It is also suitable for beginners to get some experience. After getting some knowledge and learning, you can easily start your own setup on a bigger scale. Let’s know the benefits in detail. 

Easy To Get Started

Pre-equipped aquariums are perfect for beginners and advanced aquarists, especially those on budget limits and want something quick and easy to set up. 

One big mistake people make when buying their fish tank and equipment separately is realizing later down the line that they don’t work together like intended.

Includes Everything You Need

If you were a cook, what would you like? All the ingredients are ready, or you want to collect them all by yourself. If you like everything arranged earlier, then premade tanks are for you. All-in-one aquariums ensure all are ready, and you just need to cook (read fishkeeping) according to your preference.

Most all-in-one aquarium kits include primary aquarium gears to get you started. In general, it consists of a fish tank, LED light system, and a three-stage filtration system. However, some starter kits, for example, GankPike 8-Gallon Saltwater Fish Tank, include a heater and protein skimmer. 

Therefore, you don’t need to buy equipment separately. Instead, you are getting those along with the kit, which will save your time. But keep in mind that the kit will not provide fish, corals, or something like substrate.

Often Cheaper Than Buying Separately.

If you buy every piece of equipment independently, there is a chance that it might cost more than the pre-equipped aquarium kit. On the other hand, when purchasing an aquarium starter kit, you will always have the option to upgrade or buy the missing equipment as per your demand. 

Hopefully, your kit contains everything you need to get started. But if it didn’t, don’t worry! Many items are not included in kits and can vary from one brand to another brand. 

So, I recommend only spending 60% on the initial purchase, which leaves room for additional feeders or heater/UV sterilizer combinations depending upon what type of fish you’re keeping. 

Disadvantages Of Premade Aquarium Kits

There are some disadvantages as well. Pre-equipped tanks make your options limited. Going for premade tanks limits the option to expand in the future when you are ready to experiment with some advanced things.

That could be the case only if you buy smaller size aquariums. Go for larger tanks such as SCA Gallon Starfire aquarium or Seaclear Acrylic Aquarium. Then, there will be no way of stopping you from growing for a very long time. 

Another downside is the quality; sometimes, the tank and the gears are not as good as you would like. However, we carefully chose the kits here so that you can enjoy the best quality. But, you can go wrong and simply not suit everyone. 

Wrapping Up

I know you’re excited to get started on your very own marine aquarium-I am, too! I believe it’s crucial to provide the best reviews of the best saltwater fish tanks available to decide which one is perfect for you. 

However, my top choice is SCA 50 gallon Starfire glass tank because, in my opinion, it’s hands down the best saltwater fish tank on the market. In addition, it comes with a complete package (except a light and a heater) that allows you to start out and easily grow into it. So there are no restrictions or limitations as your marine aquarium grows over time. 

If you don’t have the budget, I recommend going for Coralife LED BiocubeFluval Sea EVO V, or Innovative Marine Nuvo Fusion. Although, any of the items will be a great starting point to your saltwater hobby.
