Aquarium 101: Choosing the Right Fish and Critters for a 5 Gallon Tank
Are you thinking of getting an aquarium but are unsure of where to start? A 5-gallon tank is a popular size for beginners and those who want a small aquarium that doesn’t require much space.
In this article, we will discuss suitable fish and critters for a 5-gallon tank, their key characteristics, and care requirements.
Suitable Fish for a 5 Gallon Tank
Chili Rasboras (Boraras brigittae)
Chili Rasboras are popular among hobbyists due to their vibrant red color and their easy-to-care-for nature. These schooling fish thrive in groups of six or more and are carnivorous, which means they require protein-rich foods such as frozen or live foods.
They prefer a slightly acidic water pH (6.0-7.0) and enjoy a planted tank with a good amount of open swimming space. Endler’s Livebearer (Poecilia wingei)
Endler’s Livebearer is another popular fish for a 5-gallon tank.
These brightly colored fish are easy to care for and can be kept in a group of males only, as males are more colorful and active. They’re omnivores, eating a mix of plant and animal-based foods.
They do well in a planted tank with a good amount of open swimming space and require a slightly alkaline water pH (7.0-8.0).
Fancy Guppy (Poecilia reticulate)

Betta (Betta splendens)
Bettas, also known as Siamese Fighting Fish, are a popular fish species for beginners. They have stunning colors and patterns and are aggressive toward other fish, so they do best in a singular tank occupancy.

They require a protein-rich diet, and live or frozen foods are ideal. They prefer a slightly acidic water pH (6.5-7.5) and a planted tank with some hiding spots and open swimming space.
Honey Gourami (Trichogaster chuna)

Suitable Critters for a 5 Gallon Tank: The Importance of Balance Maintenance and Flagship Species
A 5-gallon tank provides the perfect opportunity for beginners to start their aqua journey. While it may seem like a small water volume, it’s important to remember that every inch counts and every animal added contributes to the overall bioload.
Therefore, it’s essential to find the right balance between maintenance and the well-being of the inhabitants by choosing suitable critters. This article expands on the types of fish and invertebrates and why they can make great additions to a 5-gallon tank.
Suitable Bioload and Flagship Species
When considering the bioload of a 5-gallon tank, it’s vital to select the right animals to ensure that there is a healthy balance within the ecosystem. The bioload is the amount of waste produced by the animals living within the tank.
The more organisms added, the greater the bioload. The bioload is essential in determining how much of the waste can be processed by the beneficial bacteria living in the substrate, filter, or any surface area of the tank.
Therefore, it’s important to make sure that the tank’s overall bioload level is within limits that the beneficial bacteria can handle. One of the best ways to maintain a balanced bioload is through a flagship species, which is the focal point of your tank.
Flagship species are animals that stand out and have enough personality to keep the aquarist engaged and motivated to perform the necessary maintenance tasks. They are the backbone of the aquarium, and other animals are added to complement or enhance their living arrangements.
Small Water Volume Customers
A 5-gallon tank limits the number of animals that can be added due to its small water volume. However, this does not mean that the aquarium should be less interesting or enjoyable.
In fact, smaller tanks can often provide a more intimate and captivating experience.
Cleanup Crew
To maintain the cleanliness of the tank, the use of a cleanup crew is essential. Cleanup crew refers to animals that help with the elimination of algae, excess waste, and debris in the aquarium.
Some examples of cleanup crew for a 5-gallon tank include cherry shrimp, amano shrimp, and nerite snails. These animals are remarkably efficient in the removal of debris and waste, making them the perfect candidates for small tanks.
In addition to cleaning the tank, Cherry shrimp are a great addition to the ecosystem as they help maintain the plant life in the aquarium. They feed on algae and uneaten food and release nitrates and phosphates that are essential for plant growth.
Jewel of the Aquarium
The Betta is a popular choice for flagship species in a 5-gallon tank. Bettas are beautiful, graceful, and full of personality.
They’re easy to care for and require only basic maintenance. The small space of a 5-gallon tank maximizes their beauty and allows for a closer look at their behavior.
However, Bettas can be aggressive and territorial, so it’s important only to keep one Betta fish per tank. Other choices for a flagship species could be the Endler’s Livebearer, Fancy Guppy, and Killifish, among others.
These fish are colorful, active, and full of life, making them great additions to the smaller aquarium and help balance the tank’s bioload. These fish are also easy to care for with low maintenance.
Invertebrates
Invertebrates are a great addition to the 5-gallon tank. Snails, shrimp, and other small invertebrates have low bioloads and make great cleanup crews for the tank.
They can help keep plants healthy, and some invertebrates also have interesting behaviors that can be observed. Mystery Snails are great invertebrates to keep for beginners.
They eat dead plant matter, uneaten fish food, and algae. They also come in a variety of colors that can add to the charm of the aquarium.
Conclusion
In conclusion, a 5-gallon tank can be a great addition to any aquarist’s home and provides an excellent opportunity to explore the world of aquarium keeping. When selecting suitable critters for a 5-gallon tank, it’s essential to keep in mind the bioload and maintaining balance throughout the ecosystem.
The use of a flagship species can help guide the selection of other animals for the tank, and a cleanup crew is essential for keeping the aquarium clean. Don’t be afraid to experiment with different combinations of fish and invertebrates and let your creativity soar!
In conclusion, the article emphasizes the importance of selecting suitable critters for a 5-gallon tank based on bioload and balancing within the ecosystem.
The use of a flagship species can help guide the selection of other animals, and a cleanup crew is essential for maintaining the aquarium’s cleanliness. Though the available choices for a 5-gallon tank are limited, it doesn’t mean that the tank will be less interesting or enjoyable.
In fact, smaller tanks can provide a more intimate and captivating experience. Remember to experiment with different combinations of fish and invertebrates and let the creativity soar!
