Choosing the right reef aquarium size can be one of the most difficult tasks for anyone new to keeping saltwater tanks.
Like many things, I chose to learn the hard way what to avoid when getting started. My first saltwater aquarium was a 20 long!
So, I figured, now that I have most of this figured out, I should share my knowledge to help you avoid the same mistakes I made.
The best beginner reef size is typically a 40 gallon breeder. But if you can go larger, they will be even easier to maintain!

Choosing The Perfect Size
It might go without mentioning, but the first thing you need to consider is your available space. Don’t buy a 75-gallon tank if you only have room for a 30-gallon.
You also need to consider costs. For the most part, the larger your tank is, the more it will cost to set up.
Many factors affect pricing:
- The tank itself
- Available stands
- Lighting requirements (typically one of the largest expenses)
- Filtration requirements
- Live rock and sand
- And more!
However, the larger you go, the easier it will be to maintain your tank. Trust me—I’ve been there! A big tank is your friend.
Understanding the Basics of Reef Tank Sizes
When it comes to reef tanks, size matters.
But don’t worry, I’m not talking about who has the biggest aquarium on the block. You want to find the sweet spot that works best for you and your underwater pals. Here are some common tank sizes that are perfect for beginners:
- 40-gallon breeder: Not too big or small, just right for starting your saltwater journey.
- 60-gallon cube: This beauty will add a touch of modern style to your living room.
- 75-gallon: Another affordable option if you have the space for it!
- 90-gallon: For those who want to create a stunning underwater landscape, this size tank gives you plenty of room to play.
- 120-gallon and larger: If you’re feeling extra ambitious (and have the space), these bigger tanks offer even more possibilities for your reef paradise.
Factors to Consider When Choosing a Reef Tank Size
Now that you know the basic tank sizes, let’s explore what you should consider when making your choice.
Space and Location
First things first, measure your available space.
You don’t want to buy a massive tank only to realize it won’t fit through your doorway! Consider where you want to place your aquarium and make sure it can support the weight of your chosen tank size.
Budget
Let’s face it: reef tanks can be a bit of an investment. But don’t let that scare you off! While larger tanks generally cost more upfront, they can actually be more cost-effective in the long run. Plus, you can’t put a price tag on the joy of watching your coral grow.
Maintenance Requirements
Repeat after me: “I will not neglect my tank!”
Larger tanks typically require less frequent maintenance than smaller tanks. With more water volume, your aquarium will be more stable and forgiving of minor mistakes. But don’t forget, even the biggest tank will need some TLC.
You really can’t underestimate the power of a water change.
Stability and Water Parameters
Speaking of stability, larger tanks are less prone to sudden changes in water parameters, which is crucial for keeping your fish and coral happy and healthy.
A slight hiccup can quickly become a big problem in a smaller tank.
Livestock Goals
Do you dream of a tank filled with colorful fish and coral? Or are you content with a few easy-to-care-for critters? Your livestock goals will play a big role in determining the best tank size for you. Remember that some fish need more swimming room, while certain corals require very specific water parameters.
Look into the fish you want to keep to help determine the best size for your first tank.
The Ideal Reef Aquarium Size for Beginners
Drumroll, please! After weighing all the factors, the ideal reef tank size for beginners is between 40 and 90 gallons. This range offers the perfect balance of ease of maintenance and long-term success.
- 40-gallon breeder tanks are a great starting point for those who want to dip their toes into the saltwater world without diving in headfirst. They’re affordable, easy to maintain, and still offer plenty of room for a few fish and coral.
- 60-gallon cube tanks are perfect for those who want to make a statement with their aquarium. The unique shape allows for creative aquascaping and provides a stunning centerpiece for any room.
- 90-gallon rectangular tanks hit the sweet spot for many beginner reef enthusiasts. They offer ample swimming space for fish, plenty of room for coral growth, and a stable environment that’s easier to maintain than smaller tanks.
Plus, starting with a larger tank means you won’t outgrow it as quickly. Trust me, once you’re bitten by the reef tank bug, you’ll be itching to grow.
Common Mistakes to Avoid With A Beginner Tank
Now that you know what to look for in a beginner reef tank, let’s talk about some common pitfalls to avoid.
- Starting too small: While a nano tank might seem cute and manageable, it can be a real challenge for beginners. Smaller tanks are more prone to fluctuations in water parameters, which can quickly lead to disaster. Stick with a tank that’s at least 40 gallons to give yourself some wiggle room. You can always get a nano reef after you’ve mastered your new tank.
- Choosing an unconventional shape: I know a hexagonal tank looks super cool. But when it comes to reef tanks, stick with the classics. Rectangular and cube tanks are easier to maintain and provide better swimming space for your fish.
- Underestimating the importance of water volume: Don’t be fooled by the size of your tank. The actual water volume is what really matters. More water means more stability, which is key to a thriving reef tank. So, when in doubt, go for the bigger tank.
Low-Maintenance Reef Tank Considerations
Now, I know what you’re thinking. “But I don’t want to spend all my free time maintaining my tank!” Don’t worry. There are plenty of ways to set up a low-maintenance reef tank that still looks amazing.
Sump and Filtration
A sump houses your filtration system, heater, and other gadgets, keeping them out of sight and making maintenance a breeze. Plus, it adds extra water volume to your tank, which means more stability for your little slice of the ocean.
Lighting and Equipment
When it comes to lighting your reef tank, LED is the way to go. Not only do they save on energy costs, but they also produce less heat than traditional bulbs. This means less stress on your tank’s cooling system and more money in your pocket.
Automation and Simplification
Who says you have to do everything by hand? You can automate many of your tank maintenance tasks with the right equipment. From automatic top-off systems to programmable lighting and feeding schedules, plenty of ways to simplify your reef tank routine exist.
Choosing The Best Beginner Saltwater Aquarium
You’ve got this. By choosing the right-sized tank, investing in quality equipment, and maintaining a regular maintenance routine, you’ll be well on your way to creating a stunning reef tank that will bring you joy for years.
Remember, the best tank size for beginners is one that balances ease of maintenance with long-term success. A 40-90 gallon tank offers the perfect sweet spot for most beginner reef enthusiasts.
So, what are you waiting for? Go forth and create the reef tank of your dreams! And don’t forget to have fun along the way. After all, that’s what this hobby is all about.
