25 Best Fish For A 10 Gallon Tank

If you ask me! Fish are the best pet to keep. These beautiful creatures that come in varieties have caught the attention of many people in recent years. And, being myself an aquarist, who am I to object? But have you ever wondered that all the people might not have the same room to keep a tank or aquarium in the house! If you have a smaller, like 10-gallon tank, what will be the best fish to keep?

Some fish that fit quite well in a 10-gallon tank are betta fish, guppy fish, Kuli Loaches, rice fish, Endler’s Livebearer, Chili Rasboras, and White cloud Moutain Minnow. Along with them, a few very popular among aquarists are Neon tetras, Ember tetras, Cardinal tetras, freshwater shrimps, and Mollies.

However, there are still many more to add to this list, and I will tell you everything about all the fish that can be best for a 10-gallon tank. So, stay with me till the end.

Ideal Number Of Fish For A 10-Gallon Tank: How Many Can You Have?

You’ve probably heard that you shouldn’t put too many fish in a tank. But how many is too many? It’s actually pretty simple to figure out the maximum number of fish your tank can hold. The rule of thumb is one inch of fish per gallon of water. So, for a ten-gallon tank, you could have ten one-inch fish, five two-inch fish, or a combination of sizes that add up to ten inches.

Of course, this rule is just a starting point. There are many other factors to consider, such as the type of fish you want to keep, temperament, size, and water needs. For example, some fish are more active than others and produce more waste, needing more space. Other fish are sensitive to changes in water quality and need a bigger tank to dilute the impact of their waste.

If you’re not sure what kind of fish you want to keep, a good rule is two gallons per fish. So, you could have five or even fewer fish for a ten-gallon tank. Remember, it’s better to err on the side of too much space than too little. Your fish will be happier and healthier in a roomier tank.

What Should You Consider When You Keep Fish In A 10 Gallon Tank?

As an owner, you definitely hold all the responsibilities for the health and well-being of your fish, don’t you? But, especially when you have a smaller tank, you need to be extra careful about many things if you want your fish to be happy. So, what should you know before you stock your tank with fish?

If you have no idea about it, don’t worry, I am here to help you. I am listing out some of the basics before you put fish in a 10-gallon tank.

Rule Of One Inch Per Gallon Doesn’t Stand Out Everywhere.

You might have often heard the rule of thumb, “one inch of fish per gallon of water.” Well, this doesn’t work in every case. It is only a general guideline that works for many freshwater fish. But there are still some exceptions to it.

Some fish like goldfish can grow very large, needing more than 12 inches or 30 cm of space. In contrast, some fish can do well even if they do not get a tank per gallon equivalent to their size in inch.

So, you better not fall into the trap of this myth. Instead, please do some research on the size a fish will grow into and make sure they have enough space in the tank.

Aquarium Isn’t As Big As You Think.

In fact, most of the time aquarium will hold lesser water than the size it is written on. For instance, a ten-gallon aquarium will only hold about eight gallons of water. This is due to the space taken up by gravel, decorations, and the air inside the tank itself.

This is why you need to be really careful while stocking fish in your aquarium because a smaller tank means less area for your fish to move. As a result, there will be higher chances of overcrowding and bullying.

Being new in fish keeping, I know you want to keep every fish possible in your tank. But it surely doesn’t work that way.

Every Fish Has Distinctive Characteristics And Needs

You might think all fish are the same and have similar needs. But this is not true at all. In fact, every fish has distinctive characteristics that make them different from one another.

For example, like Guppies, some fish is very peaceful while others can be aggressive. So, before you add any fish, you should be familiar with the fish’s characteristics, behavior, hardiness, and size. All these things go well if you want to keep the fish in your 10-gallon tank until their expected lifespan.

Sometimes owners think that having a smaller fish will work best for a small tank. But that’s not always the case. A small fish also needs some space to move and hide. So, do not make this mistake of thinking all small fish are good for a smaller tank.

Having said that, what do you think are the best fish for a 10-gallon tank? If you do have a specific fish in mind, please share it with us in the comments.

What Are The Best Fish For A 10 Gallon Tank?

Off course, 10 gallons is a small tank, and you might think that there might be too few options for fish to keep in there. But to your surprise, you will find a huge variety of fish that can fit well and live happily in a 10-gallon tank.

So, what are they then! I have tried pointing out most of them and giving a brief account of each of them below. I just hope you will find everything fruitful.

Mollies

molly fish

Mollies are a great option for a small tank like yours. They are peaceful, hardy, and can grow up to four and a half inches in length. These freshwater fish are one of the most popular fish among aquarists.

You can easily keep about 2-3 mollies in a 10-gallon tank. They are livebearers and give birth to fry quite often. So, if you’re planning on breeding them, it’s better to keep a single male with two females. Mollies are social creatures and love company. They are also known to be good community fish.

Guppies

Guppy Fish Care

Guppy fish is another quite common family of fish that fascinates most fish keepers. These fish are very easy to take care of and can grow up to two and a half inches. Usually, females are a little larger than males.

When we talk about Guppies, one thing that I must mention is their magnificent color. They come in a variety of colors and patterns. So, if you want your tank to be colorful and attractive, these are the fish you should go for.

In general, you can keep up to four guppies for a tank of your size if you ask me! I would suggest only 3. It is always better to keep it to a minimum than overstock them.

Kuhli Loaches

Kuhli Loaches

Kuhli Loaches are peaceful community fish that do well in a group of at least four. These beautiful eel-shaped fish is also known as shy fish because they are nocturnal. They do not prefer light and will spend most of their time hiding, so it’s important to provide plenty of places for them to hide. Driftwood, rocks, and plants make good hiding spots for kuhli loaches.

Owing to the small size of 3-5 inches, you can keep around four fish in a 10-gallon tank. If you can maintain the water condition well, these fish can live up to 10 years.

Betta Fish

black orchid betta

Betta fish are one of the most beautiful freshwater fish you will find in the market. They are very easy to take care of and can grow up to three inches.

Bettas are solitary fish and do not like company. So, it is better to keep only one Betta per tank. If you put more than one, there is a high chance that they will fight and might even kill each other.

Apart from that, Bettas are very territorial and need a lot of space to roam around. So, I would not recommend keeping more than one Betta fish for a tank as small as yours.

Rice Fish

medaka rice fish

Rice fish are peaceful and social creatures that do well in a group. These beautiful small fish are only around one and a half inches long. So, they can easily fit in a small tank as small as 10 gallons.

Rice fish are hardy fish with beautiful coloration. Thus they are quite popular. You can easily keep a group of six to eight rice fish in a tank of 10 gallons. Just make sure that you provide them a perfect water condition that resembles with their native habitat.

Endler’s Livebearer

They are also relatively small, measuring only about 2 inches in length. 

Additionally, they have a peaceful temperament and do well in groups. For these reasons, Endler’s Livebearers make ideal fish for beginner aquarists. When keeping Endler’s Livebearers, it is important to maintain a water temperature of around 75 degrees Fahrenheit. They also prefer slightly alkaline water, with a pH level between 7.0 and 8.0. Lastly, it is best to keep them in groups of 3 or 4 fish. This will help them to feel more comfortable in their environment and thrive.

Chili Rasboras

Chili Rasboras

Chili rasboras are small, peaceful fish that are native to Southeast Asia. They are popular with aquarium enthusiasts because of their attractive coloration and easy-going nature. Chili rasboras are also well-suited to life in a 10-gallon tank. They only grow to be about 1.5 inches long, so they don’t need much space. They also do well in a community tank as long as they are kept with other peaceful fish. 

When kept in a 10-gallon tank, it is best to keep a school of at least six chili rasboras. This will help them feel comfortable and decreases the likelihood of aggression. Chili rasboras prefer slightly acidic and warm water, so be sure to check your water parameters before adding them to your tank. All in all, chili rasboras make an excellent addition to any 10-gallon aquarium.

White Cloud Minnow

White Cloud Mountain Minnow

The White Cloud Minnow is a small, peaceful fish native to the cool, clear waters of China. Because of their size and temperament, they are a popular choice for fishkeepers with smaller tanks. In fact, White Cloud Minnows are often seen as the perfect fish for a 10-gallon tank. 

Although they are relatively hardy, they prefer slightly cooler water temperatures and higher dissolved oxygen levels. For this reason, it is important to maintain proper water parameters if you decide to keep White Cloud Minnows. 

An ideal number to keep in a 10-gallon tank is between 6 and 8 fish. Or you can opt for only five of them in 10 gallons like me. After that, it’s up to you! I always suggest going for the optimum number rather than overstocking them. 

Celestial Pearl Dianos

Celestial Pearl Danios

Celestial Pearl Danio, also known as Galaxy Rasbora, is a beautiful freshwater fish that originates from Myanmar. They have an iridescent green body with dotted patterns of blue and white. 

Celestial Pearl Danios are relatively small, only growing up to about an inch long. They are peaceful fish that do well in groups, so an ideal number to keep in a 10-gallon tank would be 5 or 6. They prefer slightly acidic water with a temperature range of 72-79 degrees Fahrenheit. 

Celestial Pearl Danios are popular among fishkeepers because of their striking coloration and peaceful nature. They make an excellent addition to any aquarium.

Zebra Danio

Zebra danios are a type of small freshwater fish native to Africa. They get their name from their unique stripes, which can be either black or brown. Zebra danios are popular for aquariums because they are relatively peaceful and do not grow too large (most only reach around 2 inches in length). They also do well in various water conditions, making them easy to care for. 

When kept in an aquarium, zebra danios should be kept in at least 3-5 fish groups. This will help them feel more comfortable and less stressed. 10 gallons is a good tank for zebra danios. Also, because they are such social creatures, it is important to provide them with plenty of hiding places and places to explore. You can use aquarium gravel or rocks to create these spaces. 

However, Zebra danios are not known to be fin nippers, but they may nibble on slow-moving fish or long-finned fish. So, you must be very careful about your tankmates when keeping them in a small 10-gallon tank.

Dwarf Corydoras Catfish

Corydora catfish

Dwarf corydoras catfish are popular not only because of their size—which makes them ideal for smaller tanks—but also their temperament. They are a peaceful species that do well in groups, so long as at least one other corydoras species are present.

 As for numbers, a good rule of thumb is to keep no more than three corydoras catfish per 10 gallons. In terms of water parameters, dwarf corydoras prefer neutral to slightly acidic water temperatures between 72 and 79 degrees Fahrenheit. They are also relatively easy to care for, making them good for beginner aquarists.

Peat puffers prefer water on the acidic side, with a pH of 6.5-7.0 and a temperature of 74-80 degrees Fahrenheit. They are not particularly demanding for water parameters, but they do require a bit of care when it comes to feeding, as they are notorious fin nippers.

Dwarf Gouramis can make a beautiful and low-maintenance addition to any freshwater aquarium with proper care.

Freshwater Shrimp

Shrimp is a popular addition to many aquariums because of their size and temperament. Freshwater shrimp are small, only growing to be about an inch long. This makes them ideal for smaller tanks, like a 10-gallon. Shrimp are also relatively peaceful, making them good for community tanks. 

In terms of water parameters, shrimp prefer slightly alkaline water with a temperature range of 68-77 degrees Fahrenheit. However, they are also relatively sensitive to ammonia and nitrites, so it’s important to maintain good water quality in a shrimp tank. 

Furthermore, shrimp are scavengers and will eat just about anything.

They prefer neutral to slightly acidic water with a temperature of 76-82 degrees Fahrenheit. 

What Are The Problems In A 10-Gallon Tank?

While a ten-gallon tank can certainly house a smaller fish, several potential problems can occur.

One of the biggest problems is that a ten-gallon tank doesn’t offer much in terms of swimming space. This can be especially hard on active fish who need to move around a lot. You cannot keep enough substrates or decorations in a ten-gallon tank to provide hiding places for all your fish, either.

Furthermore, a ten-gallon tank can be difficult to keep clean. This is because the smaller volume of water means that it’s easier for waste and toxins to build up. As a result, regular water changes are essential.

A ten-gallon tank can be more prone to temperature fluctuations. This is because the small volume of water means that it heats up and cools down more quickly. As a result, you’ll need to be extra diligent about monitoring the temperature of your tank.

Are you also struggling with a 10-gallon tank? How do you solve these problems?

Setting A 10 Gallon Tank And Solving The Problems

When you keep your beautiful pals in a small tank, you are sure to face some problems. But if you are careful enough while setting your tank and maintain it well, you will not have to face any big issues.

If you are having a problem setting in setting and maintaining your tank. Here are a few things you need for your 10-gallon tank and how to set them up.

Filtration System

Filtration is the key to a successful and healthy small tank setup. A good filter will help keep the water quality high and help remove waste products from the water. Setting an ideal filtration system does not needs much effort. You can get the hang of it with a little bit of research.

Using Heaters

If you are keeping tropical fish, you will need to provide them with a warm environment. For this, you will need to set up a heater in your tank. It is advisable to get a submersible heater as they are easy to install and maintain. Generally, the water temperature is crucial for the healthy life of your fish. So, you must use an appropriate heater and regularly monitor the water’s temperature.

Ideal Lighting

Lighting is not required for all fish tanks. But if you are planning to keep live plants in your tank, you will need to provide them with adequate lighting. You can choose from a variety of aquarium lights available in the market. However, I usually suggest not using too much lighting in a tank as it can cause algae growth or even disturb the sleep cycle of your fish.

Maintenance Of Tank

Maintaining a small tank is not a difficult task. You just need to be consistent with your cleaning and water changes. I would suggest doing a water change of about 20-25% every week. If you do so, it will help keep the water quality high. And also prevent the build-up of waste products in the water.

Testing The Water Quality

Testing the water quality is very important in a small tank. This will help you keep an eye on the ammonia, nitrite, and nitrate levels. I usually test the water quality every week or two weeks. Either do the same as me or check it every ten days. But do not do beyond two weeks.

However, for water testing, you can use a test kit readily available on the market.

Cleaning Your Tank

Cleaning a smaller tank like the 10-gallon one is one of the most daunting tasks. But if you do it regularly, it will not be that difficult. I would suggest using a gravel cleaner to clean the gravel and a sponge to clean the glass. You can also use an algae scraper to remove algae from the glass. This will help remove the waste products from the gravel and keep the water quality high.

Keeping Plants

If you plan to grow plants in your tank, you need to provide them with adequate lighting and nutrients. You can use a variety of aquarium plants for this purpose. However, I would suggest using live plants as they are easy to maintain and provide a natural environment.

Some of the best plants for a small tank are Java fern, Anubias, and Cryptocoryne. These plants are easy to maintain and provide a natural environment for your fish.

So, these are a few things that you need to keep in mind while setting up your small tank.
