What tank size do angelfish need?

Angelfish are territorial and semi-aggressive and require a large aquarium size to house them.They also need ample free swimming space to shoal together.

The 30 gallon aquarium is suitable for two adult angelfish along with a few other fish.

It is also important to remember that angelfish species tends to be taller than it is long.So,always keep angelfish in tall aquariums rather than wide ones.

Angelfish are best kept in aquariums with other angelfish. Although they are more communal fish when they are young,they become more territorially aggressive as they mature. So it’s better to keep them in separate tanks.

There are many things to consider when installing an angelfish aquarium.

It is important to select the right tank companions and ideal water parameters that  match their likings. But above all , it’s important to make sure you have the right tank.

Angelfish body size

Angelfish come from South America and are a diverse group of cichlids. It features a long, thin and compact body and various colors and patterns.

Angels are usually very peaceful in their own species, but can be aggressive in other species, especially if they are small in size. Freshwater angelfish are said to be about 6 inches or 15.24 cm long, and their fins can grow up to 8 inches or 20.32 cm long.

They are four times as long as neon tetras.Angelfish have a different shape as compare to other cichlids,they have a circular body, triangular dorsal fin and anal fin.

The unusual diamond-shaped body makes it easy to hide and move roots and plants.Angelfish in the wild have been known to grow up to 10 inches, but the average size of freshwater aquarium angelfish is 6 inches.

They grow quickly at first, reaching 4 inches in length in 6 months, but it can take up to a year or more in some cases to reach full size.

Ideal tank size for angelfish

Freshwater angelfish grow large and require a 55 gallon or larger aquarium when fully grown.Long aquariums are best to accommodate their size.

The water flow should be gentle, and the tank decorations should include large broadleaf plants and vertical driftwood to simulate fallen branches and trees.

Angelfish keepers need at least 20 gallons of water for a pair of freshwater angelfish and a 80 gallons tank to start a small school. Each freshwater angelfish in the tank needs at least 10 gallons.

Is it possible to house two angelfish  in a 20 gallon tank? 

If angelfish are very young and small,then they can be kept together for a short time, but as they age,they become aggressive and start killing each other after a few months due to lack of space and resources.

And to be honest,If you’re very lucky enough, and get a pair, you can fit two in the 20-gallon tank.

The implementation of maintenance schedules needs to be very consistent. Keeping four angelfish in a 20 gallon aquarium will not work in the long run.

How many angelfish should be housed together? 

Most  angelfish experts recommend maintaining them in schools of at least 5 or 6. If the tank  has enough space, there is no reason why you can’t keep more than 6 angelfish together at one time.

But make sure not to overcrowd the tank, overcrowding can stress them and even the main reasons for various kinds of infections too.

Multiple angelfish housing requires skillful management.In addition to aquariums of the right size and proper layout, careful monitoring is key to keeping them happy and healthy.

It is possible to have more than one angelfish, but it takes a very large aquarium and a lot of experience to understand what to do if a problem occurs.

If you have a large aquarium and plan to add a handful of angelfish, make sure the aquarium is well planted and give it plenty of spots to hide.

How many angelfish can be housed in a 75 gallon tank?

Angelfish are schooling fish, that means they can’t be kept alone and they need their own type to school together, and the ideal number of angelfish for a 75-gallon tank is 6.

So, 6 would be the perfect number to form a school.Angelfish grows considerably big and becomes more aggressive as they age.

How many angelfish can be kept in a 90 gallon tank?

9-10 angelfish are enough for a 90 gallon tank, but angelfish can have problems with aggression.Starting at about 15-20 juveniles, this will allow you to separate aggressive males or females once they have reached breeding size.

How many angelfish can be kept in a 125 gallons tank?

Two or three pairs of angelfish can fit in a 125 gallon aquarium and can actually add more to this size, but things change quickly when they start laying.

If you really want to try their hierarchy in the angelfish aquarium, with the right settings, you can get away in 3 pairs in a 6-foot aquarium. 

What is the ideal breeding tank size for angelfish?

It is very important to create the right conditions for breeding, so prepare a freshwater aquarium large enough to prepare the angelfish for breeding.

Try to choose a tank with a capacity of at least 20 gallons or 75.7 L and ideally 29 gallons or 110 L.Plenty of space is best for your pair of angelfish.

Why are overcrowded tanks not good for angelfish?

When the aquarium is crowded,the fish show signs of stress, aggression, toxicity and lack of oxygen.

Overcrowding causes a stress response, impedes growth, weakens immunity and makes fish more susceptible to disease.To resolve the overcrowding issue, rehome some of the fish or buy a larger aquarium to accommodate them.

If you have a lot of angelfish in a small aquarium, they can get stressed quickly and will start chasing each other, and because of this repetitive behavior,they can become very tired and show signs of stress.

If you are a new fishkeeper,it may not be easy to determine if the fish is nervous or just playing.

How to deal with overcrowded angelfish tanks?

The best way to effectively deal with tank overcrowding is to adequately replace the tank water, as this will remove high concentrations of nitrates and replace them with nitrate-free water. 

Another option is to add live plants that feed on nitrates, which is another great solution to this problem.

What is the best tank companion which can be kept in an angelfish tank? 

Lemon tetra is very easy to care for and can withstand a variety of water quality conditions.

They have a peaceful nature and any kind of community fish will be okay,if they are not bullied or get eaten by their tank mates.

For these reasons, lemon tetras are considered as great tank mate for angelfish. Lemon tetra prefers to be kept in schools of 6 or more.

Why are bigger and spacious tanks better for angelfish?

Large aquariums contain a large amount of water, which makes the temperature stability of large tanks much higher.

It will take more time for the water temperature and quality to affect the inhabitants. Therefore, maintenance is much easier.

The larger the aquarium, the more stable the water, and decisively, the easier it is to stay stable.

Larger tanks take longer for ammonia to spike, which increases the time it takes to react in the event of a problem.

So,It’s very important to house your angelfish in such spacious tanks to keep them happy and healthy.

Summary

Ideally, a 29-gallon tank should be used for an angelfish.You can keep more than two angelfish in a 29 gallon tank or you can also keep them in a less than 29 gallon tank like 10 to 20 gallons.

But then you will have to change the water as frequently which can happen every day.

Each adult angelfish requires about ten gallons of water to live comfortably and happily.

Lack of swimming space and overcrowding of the tank  with too many of them along with other tank companions can lead to territorial fights.

More space is better than less because angelfish tend to be very big eaters, which means they  will produce a lot of waste in their tank.

Frequently asked questions

What tank size is needed to accommodate five angelfish together?

A thirty gallon tank is needed to accommodate five angelfish together.

What tank size is needed to accommodate four angelfish together?

A 40 gallon tank is needed to accommodate six angelfish together.

What tank size is needed to accommodate six angelfish together?

Can you keep the angelfish in the aquarium alone?

Angelfish like to flock together, but ultimately it’s up to the individual. The more angels you keep together, the more likely they are to be paired, and they will terrorize everything else in the tank.

Why taller tanks are better for angelfish than wider ones?

Angelfish fish are long in shape, so they prefer tall tanks rather than wide ones. Tall tanks provide ample open space between their long fins and the decoration and base of the tank for a safer environment.
