Raising The Blushing Angelfish: An Attractive and Hardy Species

Angelfish are one of the most popular freshwater fish species. They are colorful, peaceful, and relatively easy to care for as long as their basic needs are met. They have been around in the aquarium hobby for many years and their popularity has only grown. Over the years, several varieties of angelfish have been developed, with the Blushing Angelfish being one of the most beautiful and sought-after.

The Blushing Angelfish is a stunning fish with two red gills that make it look like it could be blushing, which is probably where its name comes from. Its Gill cover, or operculum, is not very pigmented, letting the bright red of the gills to show through. You'll notice that this fish has none of the dusky markings or hints of stripes that others do; its only distinguishing feature is the light flush on its cheeks.

This variety of angelfish makes an excellent addition to any freshwater aquarium. In terms of care, they are hardy and easy to manage as long as their water parameters are monitored and kept consistent.

Blushing Angelfish Size

Blushing Angelfish can grow up to 6 inches in length, though they will generally reach a maximum size of 4-5 inches in home aquariums. This is due to the lack of space and proper nutrition they receive in captivity.

For the best health, Blushing Angelfish should have a 30 gallon tank. This will provide them with plenty of room to swim and the ability to establish their own territories. Other factors that determine the size of the fish tank include the number of fish and the species they are kept with, diet, and water parameters. Genetics also play a role in how large the fish can get.

Blushing Angelfish Lifespan

The Blushing Angelfish has a lifespan of 10-15 years when properly cared for. This is due to the fact that they are hardy fish and are generally easy to care for as long as their basic needs are met.

Providing proper nutrition, clean water, and the right tank mates will allow them to live longer and happier lives in captivity.

Blushing Angelfish Behaviour

The Blushing Angelfish is a semi-aggressive fish, meaning it will usually do well with other fish of similar size. They can be territorial and may become aggressive towards their own species or other tankmates if they are kept in overcrowded conditions.

It's important to provide plenty of hiding places in the aquarium so that each fish has its own territory to feel safe. These fish tend to be quite peaceful and usually get along with other fish species that are not too aggressive.

They prefer to hang out mid-level or lower in the tank, and appreciate plenty of open swimming spaces.

Blushing Angelfish Appearance

The Blushing Angelfish is a beautiful fish. The name for this fish likely comes from its two red gills which make it appear as if the fish is blushing. The Gill cover, also known as the operculum, does not have much pigmentation; thus, allowing the red color of the gills to show through. The intensity of colors can depend on what kind of parents the particular fish had but generally speaking, they can range anywhere from pale orange to a bright red. This type of angelfish is simply called 'blushing angels.' They have no dark markings or stripes, and their bodies are usually golden. In some fish, you may also see a silver shade. Usually the golden color appears after they reach maturity. The only way to discern this fish from others is the light flush present on its cheeks; it doesn't have any of the common dusky markings or stripes.

However, like all angelfish, the Blushing Angelfish has a distinctively tall and triangular body shape. It also has small black eyes and a pointed dorsal fin. They have a total of five to nine spines in their dorsal fin and two to three spines in the anal fin.

Gender Differences

Males are typically larger than females and have more pointed dorsal fins. Additionally, they tend to be slimmer while females have a rounder body shape.

Also, males are typically more colorful than females and often have longer fins. Sometimes you can also see a coloration difference in the gills.

Blushing Angelfish Color Variations

These beautiful fish come in a variety of colors and patterns, however the most common color variations are:

  • Blue blushing angelfish
  • German blue blushing angelfish
  • Sunset blushing angelfish
  • Black blushing angelfish
  • Platinum blushing angelfish

Blushing Angelfish Care

Caring for Blushing Angelfish is relatively easy. However, they have specific requirements that must be met in order to ensure their health and wellbeing.

Tank Size

These fish need a tank of at least 30 gallons with plenty of hiding spaces and live plants. A larger tank (50 gallons or more) is recommended if you plan on keeping multiple Blushing Angelfish.

There are many benefits in maintaining a larger tank such as providing more territories for the fish, better water circulation and oxygenation, and eatsier maintenance.

It will also help to reduce stress, aggression, and territorial behavior among the fish.

Tank Water Parameters

Blushing Angelfish prefer a neutral water pH range of 6.5 – 6.9, although they can tolerate slightly alkaline (up to 7.6) or acidity (down to 6.2). The water temperature should be kept between 78 -84 and the hardness should be in the range of 10-15 dGH. Make sure to keep the ammonia, nitrite and nitrate levels low by doing regular water changes.

Water Quality 

In order for your Blushing Angelfish to remain healthy, you need to make sure that their tank is well-maintained with good filtration. To do this, you should use a high quality filter and perform regular water changes of 25-30% weekly.

You may also want to invest in an aquarium gravel cleaner or siphon as this will help keep the substrate clean and free from debris and waste. Additionally, you should make sure to check the water parameters on a regular basis and maintain good water quality by testing for ammonia, nitrites and nitrates.

Note: While changing the water, make sure to never use hot or cold water, as this can shock the fish. Also condition the water with a dechlorinator before adding it to the tank.

Tank Decor

Blushing Angelfish are shy and timid fish so they will need plenty of hiding places in their tank. You can provide them with natural decorations such as driftwood, rocks, and live plants.

  • Plants: Live plants help to provide the fish with hiding places, as well as oxygen and refuge from predators. There are many low-light plants that can be used in a Blushing Angelfish tank such as Java ferns, Anubias, and Cryptocorynes. You may also want to include some floating plants such as Hornwort or Water lettuce. This will provide the fish with more cover and shade from the light. There are many benefits to having live plants in your tank, including oxygenating the water and absorbing nitrates which help to keep ammonia levels low. If you don't want to use live plants, you can also use artificial plants. Just make sure that whatever you choose is safe for your fish and won't damage their fins or scales. Also make sure to clean the plants properly before adding them to your tank.
  • Caves and Hiding Places: Blushing Angelfish need plenty of places to hide and explore. You can provide them with caves, tunnels, rocks and driftwood to give them some safe areas to retreat. This will also help reduce their anxiety and stress levels. These fish are sensitive to bright lights so it is important to give them enough hiding spots in the tank. Some examples of driftwood, rocks and other decorations that you can use in your tank include Malaysian driftwood, driftwood roots, lava rock, and coconut shells.
  • Substrate: A suitable substrate for a Blushing Angelfish tank is fine gravel or sand. The particles should be small enough to avoid choking the fish, but not too large that they can't consume food from it. You may also want to add some smooth rocks or pebbles to provide the fish with more visual interest and ensure their comfort.
  • Lighting: Blushing Angelfish do not require any special lighting, but it is important to provide them with enough light for their tank. You can use a natural or LED light in the tank and keep the intensity at low or moderate levels. Keeping the lights on for 10-12 hours daily should be sufficient. If you have live plants in the tank, you may want to increase the light duration.

Suitable Tank Mates

Blushing Angelfish are peaceful fish and can be kept in a community tank with other peaceful species. Some suitable tank mates for Blushing Angelfish include:

  • Corydoras catfish
  • Otocinclus catfish
  • Corydoras Dwarf cichlids
  • Gouramis
  • Tetras
  • Plecos

These fish should not be kept with over aggressive species, as they can become stressed and may even get bullied by the other tank mates. Also, do not keep them with fin-nippers or large fish that may try to eat them.

Some bad tank mates for Blushing Angelfish include:

  • Angelfish
  • Arowanas
  • Bettas
  • Cichlids

When selecting tank mates for your Blushing Angelfish, it is important to research the other species to make sure that they are compatible. This will help ensure a healthy and stress-free environment for your fish. Make sure that the tank is large enough to accommodate all of the fish and that there is plenty of places for them to hide. Remove any aggressive fish from the tank as soon as possible.

Blushing Angelfish Diet

Blushing Angelfish are omnivores and will accept most types of food. A varied diet is important for their health and wellbeing, so you should offer them a variety of foods. In the wild, they eat a range of plant matter and small invertebrates. In captivity, you can feed them the following foods:

  • Pellets: Pellets come in many different varieties and are a great way to provide your fish with a balanced diet. Look for high-quality pellets that are rich in vitamins and minerals. Sometimes, these can also contain freeze-dried insects flavour which your fish will love. Feed these foods sparingly as they can quickly pollute the water if overfed.
  • Flakes: Flakes are another great option, but they should only be used as an occasional treat. Flakes are rich in protein and contain a variety of vitamins and minerals, but they are not as nutritious as pellets. So you should not limit your fish's diet to flakes alone.
  • Frozen Foods: Frozen foods such as brine shrimp, bloodworms and artemia are all good options for a Blushing Angelfish diet. These foods are rich in proteins and will provide your fish with the necessary nutrition. However, these should be offered in small amounts to avoid overfeeding.
  • Live Foods: Live foods such as blackworms, daphnia and tubifex can also be offered to your Blushing Angelfish. These should not be fed too often but can make a great treat for your fish every now and then. However, if you are trying to breed your fish, live foods can be offered more frequently.
  • Vegetables: Vegetables such as blanched spinach and zucchini are also great for a Blushing Angelfish diet. These should be chopped into small pieces and offered to your fish regularly. You can also feed them algae wafers or spirulina flakes, which can provide them with extra vitamins and minerals.

Feeding Tips

If you want to keep your Blushing Angelfish healthy, it is important to be careful with their diet. Here are some tips for feeding Blushing Angelfish:

  • It is important to provide your Blushing Angelfish with a balanced diet, so that they can stay healthy and active.
  • Feed your fish in small amounts multiple times a day, instead of one large meal. This will help prevent overfeeding and also keep their tank cleaner.
  • Do not overfeed as this can pollute the tank water quickly.
  • To ensure your fish are getting the nutrients they need, offer them a variety of foods. This will also help keep them interested and active.
  • Do not feed them live foods too often as this can put them at risk of disease.
  • Fast your Blushing Angelfish at least once a week to give their digestive system a break.
  • Make sure that all foods are appropriately sized for your fish.

Blushing Angelfish Diseases

Like most fish, Blushing Angelfish can be susceptible to some diseases. The most common diseases affecting them include:

  • Ich: Ich (or white spot disease) is a common parasite that can affect your Blushing Angelfish. It is caused by the protozoan Ichthyophthirius multifiliis and is easily recognisable by the white spots on their body. If left untreated, it can cause death in fish.
  • Skin Flukes: Skin flukes are microscopic parasites that can infest the skin and gills of your Blushing Angelfish. They can cause irritation and stress, leading to loss of appetite, lethargy and even death.
  • Fungal Infections: Fungal infections can occur if your fish is stressed or has a weakened immune system. These infections are usually white or grey in colour and can cause skin lesions and other signs of distress.
  • Hole-in-the-Head Disease: This is a bacterial infection that causes pits and holes to appear on your fish's head. If left untreated, it can cause severe damage and even death.
  • Dropsy: Dropsy is a fatal condition caused by an imbalance of fluids in the body. It can be caused by stress, poor water quality or any other underlying health problems.

Blushing Angelfish Breading

Angelfish breeding occurs most successfully when all required conditions are present and you have a willing pair. Some angelfish couples can be picky, so it's important to get every detail perfect if you want them to breed. Following the right steps can help you increase your chances of a successful breeding.

  • Step 1: Start by preparing the tank for breeding. This includes increasing water temperature to 80-84°F, creating vegetation in the tank and adding a spawning mop or artificial plants for the female to lay her eggs on. The ph of the water should also be 7.0-8.0.
  • Step 2: Condition the pair for breeding by providing them with a high quality diet and plenty of space. This will help to ensure the health of both parents and eggs.
  • Step 3:Monitor your fish for signs of readiness to spawn by looking for courtship behaviour, such as swimming in circles or chasing each other. This usually happens when the conditions are right and the couple is ready to breed. Generally, your angelfish will reach sexual maturity between 6 and 12 months old. If you remove the eggs each time they are produced, a pair of angelfish can spawn every 7 to 10 days. To signify that they are ready to spawning, a chosen site will be meticulously cleaned by the pair of angelfish. The female fish deposit a line of eggs afterward.
  • Step 4: After the eggs have been laid, the male fish will fertilize them. The eggs will then be guarded by both parents until they hatch 2 to 4 days later.
  • Step 5: Once the fry have hatched, it is important to provide them with food and clean water as soon as possible. Small live or frozen foods are ideal for the fry.

Blushing Angelfish Fry Care

Caring for Blushing Angelfish fry can be a challenging but rewarding process. The fry will require frequent water changes and regular feedings of small live or frozen foods.

When the fry are first born, they will be very small and delicate so make sure to keep an eye on them at all times. It is important to provide them with a safe and secure environment, free of any predators or hazards.

Young Blushing Angelfish are sensitive to water quality and need frequent water changes. This is especially important in the beginning as they are still developing their immune systems. It is also important to monitor ammonia levels and keep them as low as possible.

It's also essential to provide the fry with a good quality diet. In the wild, Blushing Angelfish fry feed on small invertebrates, such as worms and crustaceans. In captivity, you can provide them with high-quality prepared foods in addition to small live or frozen foods.

You can also supplement their diet with fresh vegetables and fruits, such as cucumber, zucchini, or spinach.

As the fry grow larger and stronger, you can gradually increase the size of their food and provide them with a more varied diet. With proper care and attention, you can successfully raise your own Blushing Angelfish fry!
