The Best Size for Your Fish Tank- How To Get it Right

If you want to buy yourself a fish tank and don’t know where to begin with, scrolling down from some tips is going to help you make the right decision.

Is the size of the fish tank the first thing to consider?

First mistake people make when thinking about getting a fish tank is that they consider the size of the aquarium as primary criteria when it’s the specific breed of fish that they want to keep that matters the most.

You should give a thought about the type of fish you’d like to keep and how many fish you’re planning to take care of. Once it’s all clear to you, you should work backward and decide how big the fish should be and which kind as well.

Is a bigger fish tank a better choice?

In all fairness, the bigger the fish tank, the happier your fish is going to be. Fish that live in small and cramped environments are going to be more stressed and aggressive in time.

Besides, a larger fish tank is more comfortable to take care of (go figure!) and keeping the water clean inside the tank (chemistry and temperature) is a constant challenge. Ammonia is going to need a lot more time to spread in a larger aquarium, giving you more time to act when something goes off. You may not realize, but a 100 gallon is easier to maintain stable than a 30-gallon tank. But yet again a 30gallon tank is more comfortable to keep calm when compared to a nano tank.

What is the most common rookie mistakes?

One of the most common mistakes for beginners is to think that a “starter” tank is a smaller tank. Many fall into temptation and get a small fish tank in the beginning, no matter the size of the fish they decide to go with.

Truth be told, it’s cheaper to take care of a smaller fish tank, but it’s not the no.1 choice for a newbie. We cannot stress enough about the importance of the space that your fish needs, so using the right size is fundamental for its health.

What are the challenges of small fish tanks?

When you’re buying a small fish tank, you’re not going to face many problems. The rule of thumb is the bigger the fish tank, the happier the fish is going to be. On the other hand, when the tank is too small for your fish, the future doesn’t look good at all.

Here are the most common problems that you may have to deal with when your fish ends up in a too-small tank:

It stops growing

Many beginners think that a fish is going to develop to the size of the aquarium. But it’s not true at all. In all fairness, the myth comes from the people owning a goldfish. Goldfish are known as they continue to grow throughout their entire life. However, when you put them in a small tank, they’re going to stop developing. It’s why people think that fish are always growing to the size of their aquarium.

In reality, the fish’s growth is stunted, and their health has been compromised for good, which is why they stop growing.

Fish become more aggressive

The behavioral problems matter a lot, and they are the primary concern when using a too small fish tank. Fear, anxiety, and stress are some of the behavior problems caused by a small aquarium. High aggression is the most important one.

When fish are living in a small fish tank, they can become aggressive towards the other fish in the tank. It’s all the stress and fear they live in to.

Turning back an aggressive fish into a friendly one is difficult, so keep that in mind when you’re placing too many fish in a too-small fish tank.

The lifespan shortens

A fish that lives in a too small fish tank isn’t just going to stop growing, and become more aggressive, but it’s also going to live less. Here are the main reasons for which their lifespan shortens:

A fish in a too small space is going to stress out a lot more. Stress means more tension on the heart, which leads to overwork and premature aging.

The risk of organ failure is also increasing. When a fish stops growing, his organs aren’t going to be able to grow anymore, so the internal organ failure is right around the corner.

Is there an ideal size for the fish tank?

It’s evident by now that there are no perfect sizes for a fish tank; it’s what works the best for your fish and your space that gives you the ideal size for the fish tank.

It doesn’t mean that you shouldn’t consider some rules:

Don’t settle for a fish tank that is big enough. You should always be prepared to get a fish tank that is bigger than your fish needs. It’s going to be happier like that.

A larger fish tank is more comfortable to maintain. Cleaning and maintaining water management are more convenient to address for bigger aquariums.

Large fish tank means happier fish.

When a large fish tank isn’t a choice for you, you should look into the species of fish that love a smaller fish tank. There are many to choose from!

Where should you place the fish tank?

When you’re thinking about getting fish and a fish tank, where you’re going to place, it is also highly relevant. One may think that a fish tank goes excellent in a large room, but it’s not always true.

Here’s what makes a room an excellent option to place your fish tank:

Low noise- It’s ideal that you place the fish tank in a room on its own. Nine times out of ten it’s not going to be possible, but it’s better for the fish to place the fish tank away from any noisy sources (radio, TVs, washing machine, kitchen, and so on).

Low light- try your best not to place the fish tank in a place where direct daylight is going to shine onto it. Keep it away from skylights, windows- any place that sun is reaching quickly.

No heat whatsoever- Maintaining the temperature of the water is essential for the fish’s health. Even if the tank heater helps, keeping the air temperature around stable is just as important. It’s best that you never place the fish tank close to a heat source.

One final suggestion

Remember that there is no perfect size to fit all. Just because small tanks are more challenging, doesn’t mean that they’re not an option for anyone who has the experience and the skills to take care of it.

As long as you’re focused on keeping your fish healthy and sound, and you learn how to do it, you should be able to master this particular hobby.
