How Many Angelfish in a 55-Gallon Tank: Choosing the Best Aquarium

Are you looking for a delicate and colorful fish to add to your home aquarium? Look no further than the angelfish! These beautiful creatures are easy to care for and make a striking addition to any tank.

There are typically about six angelfish in a 55-gallon tank. Plus, they could spawn other adult fish. They should all have enough room to spread out and not be overcrowded.

What Tank Size Do I Need for One Angelfish?

If they are healthy and not overfed, a 30-gallon tank will be large enough to house one angelfish. In addition, you can add live plants to the tank. Adult angelfish don’t do well in heavily planted tanks, but you might be able to get a few other fish that enjoy live plants, and they would love it there.

How Many Angelfish Can I Keep in a 55-Gallon Tank?

A typical 55-gallon tank will host 6 Angelfish. Plus, if any spawning adults come into the tank, it could potentially house up to 8 fish in total. In addition, about a half gallon of water is needed for the fish. That amount should be enough for your angelfish to swim around, but you can always add more.

Can I Keep 10 Angelfish in a 55-Gallon Tank?

You can keep up to ten angelfish in a 55-gallon tank as long as they are all healthy and not overfed. The tank should have plenty of room to spread out, so they don’t get overcrowded. In addition, you should have at least a half-gallon of water per aquatic pet to accommodate the angelfish.

What’s the Minimum Tank Size for Angelfish?

A minimum of a 30 gallons tank is needed for one angelfish. In addition, you should have at least a few live plants.

How to Calculate Tank Size for Angelfish?

Take the number of fish in your aquarium and divide it by 2. This will give you the minimum tank size for angelfish. In addition, you should plan on having one extra gallon of space to allow the angelfish some room. Those are just suggestions, and you will want to be sure that your angelfish tank is big enough for them. The angelfish also need proper lighting, and you should also have an air stone to keep the water oxygenated.

How Many Angelfish Should Be Kept Together?

The size of an angelfish and the type will determine how many should be kept together in a tank. Generally speaking, two to four angels are the maximum number per tank. However, if you have very small or huge angels, add more by all means. Keeping too many angels together can create havoc and stress for them both. Two to four is usually about suitable for most people. The bottom line is that if you want to keep an Angelfish, be prepared to do some work on keeping them healthy and happy.

Things to Consider Before Buying an Aquarium for Angelfish

  • Size of the tank – make sure it is at least 30 gallons; they prefer a deep bottom.
  • Filter – some Angelfish prefer to have their filtration system, but others will do fine with a standard filter.
  • Decoration – adding plants or rocks can make your tank feel like theirs and gives them somewhere to congregate and hide.
  • Water chemistry – keeping the pH levels stable is essential for these fish, and any changes can stress.

Aquarium Conditions for Angelfish

Temperature

Keeping the water quality stable is essential for these fish, and any changes can stress them out. You will also want to make sure that the tank temperature stays between 78 to 84 degrees Fahrenheit at all times, as Angelfish prefers comfortable temperatures.

Water Parameters

Angelfish are not very sensitive to pH changes and can tolerate a wide range of water parameters. But, to be on the safe side, aim for a pH between 6.8 and 7.8. In addition, be sure to keep the hardness of your water as low as possible, especially if you intend on maintaining Angelfish in a reef tank.

Water Filtration

An angelfish tank needs good water filtration to keep the fish healthy. A good option is a marine land under a gravel filter. In addition, a canister filter is excellent for your angelfish tank as long as it provides good water flow.

Food and Diet

Angelfish are herbivorous fish and will eat various live and frozen foods. A good diet for your Angelfish includes:

  • Sinking pellets.
  • Different types of algae tablets.
  • Spirulina.
  • Vegetable matter such as leafy greens or carrots.
  • Small crustaceans (like feeder fish).
Spirulina

In addition, they will happily eat a variety of dry foods. There are also several premade Angelfish diets today that provide you with all the nutrition your fish needs to live and thrive.

Lighting Requirements

While many people think that an adequate light requirement for angelfish is just some sort of low-wattage lighting, this is not always the case. Many Angelfish love to have a lot of light exposure and will do better in brightly lit tanks. A good rule of thumb is to install at least three high-wattage fluorescent bulbs at an angle that floods the entire tank with light every eight hours.

Maintenance Needs

Angelfish do not require much maintenance, but they still require regular water changes and some occasional feedings. So as long as you keep these things in mind, your angelfish should be just fine.
