How Many Angelfish In A 55 Gallon Tank

If you are looking to add a school of Angelfish to your aquarium, it is important to know how many Angelfish can comfortably fit in your tank. This article will explain the factors to consider when determining the number of Angelfish that can be kept in a 55 gallon tank. We will cover topics such as fish size, tank decorations, and water chemistry so that you can make an informed decision when selecting the size and number of Angelfish for your home aquarium. Read on to learn more about keeping Angelfish in a 55 gallon tank.

Fish Size

When planning to keep Angelfish in a 55 gallon tank, it is important to consider the size and number of fish that can be housed. As a general rule, each Angelfish should have at least 10 gallons of space to themselves. Therefore, a maximum of 5 adult Angelfish can be kept in a 55 gallon tank comfortably. If you are looking to keep more than 5 Angelfish, we recommend upgrading your tank size to accommodate them.

Tank Decorations

In order for Angelfish to thrive in an aquarium, it is important to provide them with decorations and hiding spots within the tank. This allows the fish to feel secure and decreases stress levels. When providing decorations for your Angelfish, it is important not to overcrowd the tank as this can lead to territorial disputes between the fish. To ensure that all your fish have enough room, we recommend one piece of decoration per 2-3 gallons of water (roughly 20-30 gallons for a 55 gallon tank).

Water Chemistry

When determining how many Angelfish can be comfortably kept in a 55 gallon aquarium, water chemistry must also be taken into consideration. Proper water parameters are essential for keeping healthy and happy Angelfish, so it is important that you test your water regularly and make adjustments accordingly. The ideal pH range for Angelfish is 6-7 and the ideal temperature should be between 74-82 degrees Fahrenheit (24-28 degrees Celsius). Additionally, ammonia levels should remain at 0 ppm and nitrate levels should not exceed 20 ppm.

Tank Mates

Angelfish are often kept with other species of peaceful freshwater fish such as tetras or rasboras. When selecting which species will inhabit the same tank as your Angels, it is important to research each fish’s compatibility with others before making any decisions. It is also important to note that some species may require more space than what is available in a 55 gallon tank (i.e., larger cichlids or barbs), so it is best practice to stick with small schooling species when stocking your aquarium with multiple types of fish.

What Fish Can Live With Angelfish In A 55 Gallon Tank?

The type of fish that can live with angelfish in a 55 gallon tank depends on the size and number of angelfish. Angelfish are relatively large fish, and they need plenty of space to swim around and explore their environment. As such, you’ll need to make sure that there are no more than four angelfish in a 55 gallon tank.

In addition to the size and number of angelfish, it’s important to consider the temperament of other fish when determining which species are compatible with angelfish in a 55 gallon tank. Angelfish can be quite territorial, so they should not be kept with other fish that may become aggressive towards them or compete for food or space. Good community fish for a 55 gallon tank include tetras, barbs, gouramis, danios, and rasboras. These types of fish generally have peaceful temperaments and will get along well with angelfish in a larger tank like this one.

However, it is also important to keep in mind that some species may grow too large for a 55 gallon tank as they mature. Fish like clown loaches or silver dollars need tanks that are much larger than this one once they reach adulthood and should not be kept in a 55 gallon tank with angelfish. Before purchasing any new fish for your aquarium, always research the adult size of each species you’re considering adding to determine if they’ll fit comfortably with your existing setup.

What Size Tank Do I Need For 4 Angelfish?

The size of tank you need for four angelfish depends on the breed of angelfish and the type of setup you have in mind. Generally speaking, it is recommended that each angelfish should have at least 10 gallons of water per fish. Therefore, a 40-gallon tank would be suitable for four angelfish to live comfortably. However, if you are looking to keep multiple species or create an aquascape, then you may need a bigger tank.

When choosing a tank for your angelfish, there are a few other considerations to keep in mind. Angelfish need plenty of open swimming space as well as vertical space to explore and play in. Because of this, it is important that you get the right sized filter and adequate filtration so that your angelfish can thrive in their environment. Additionally, make sure that the aquarium is tall enough so that your fish won’t jump out when they become excited or stressed; it is recommended that tanks for angels should be at least 12 inches high. Lastly, it is important to choose a tank with enough surface area so that your fish can get enough oxygen from the air above the waterline.

In conclusion, if you plan on keeping four angelfish together, then you will need at least a 40-gallon aquarium with adequate filtration and surface area for them to thrive.

How Many Fish Can You Put In A 55 Gallon Tank?

When it comes to adding fish to a 55 gallon tank, the answer depends on several factors. The size and type of fish, as well as the desired stocking level and the amount of filtration are all important considerations. Generally speaking, a 55 gallon tank can house up to 15 medium-sized fish comfortably, depending on the species.

In addition to size and species, each individual fish’s needs should be taken into consideration. Some species require more space than others or may require specific water parameters, such as temperature or pH levels. Therefore, it is important to research any potential inhabitants of your tank before adding them. Additionally, overcrowding can lead to an increase in aggression among the fish and can cause stress which could result in disease or death.

In conclusion, when deciding how many fish you can add to a 55 gallon tank, it is important to thoroughly research the type of fish you wish to add and their specific needs. Taking into account size and compatibility will help ensure that your tank remains healthy and balanced for years to come. With careful consideration, you should be able to comfortably house up to 15 medium-sized fish in your new 55 gallon aquarium!

How Many Angels Should Be Kept Together?

The number of angels that should be kept together depends on many factors, such as tank size, the species of angel being kept, and the individual personalities of the fish. Generally speaking, it is best to keep only one angel in a tank unless you have a very large aquarium. This is because angels are territorial and can become aggressive if they feel their space is being encroached upon by other fish.

If you do decide to keep multiple angels together, the minimum recommended tank size is 20 gallons for two angels. If you want to add more than two angels, consider increasing the tank size accordingly. Additionally, make sure that all angelfish in the group are similar in size; otherwise, larger angelfish may prey on smaller ones. Finally, pay attention to individual behavior so that you can separate any fish that appear to be overly aggressive towards one another. By following these guidelines, you can ensure that your angelfish will remain healthy and happy in their community tank!

How Many Angel Fish Can Go In A 55?

A 55 gallon tank is a great size for housing Angelfish. Depending on the species of Angelfish, it is possible to keep anywhere from 2-6 in this size aquarium. It is important to remember that larger schools will require more space, so if you are looking for a larger school try to find an aquarium that is 75 gallons or larger.

When stocking your 55 gallon tank with Angelfish, it’s important to consider the different types of Angelfish and how they interact with each other. If you plan on keeping multiple species of Angelfish in the same tank, you should try to keep at least four or five specimens of each type to help prevent aggression and ensure the fish have plenty of room to swim around. Smaller schools can also be kept in this size tank, but it’s best to avoid overcrowding as this could cause stress on the fish and lead to health issues.

In addition, water quality must be closely monitored when housing multiple Angelfish in a 55 gallon aquarium. Ammonia and nitrate levels should be kept within acceptable levels since these can quickly become toxic if left unchecked. Regular water changes are also necessary as this will help maintain good water quality and provide your fish with a healthy environment.


In conclusion, a 55 gallon tank can comfortably house 6 to 8 angelfish. When stocking an angelfish tank, it is important to remember that angelfish are social fish and prefer to live in groups of at least four individuals. Additionally, angelfish need plenty of swimming room to be healthy and happy, so the tank should not be overstocked. With proper care and maintenance, a 55 gallon tank can provide a healthy home for a small school of angelfish for many years.
