Flame Angelfish Care: Tank Setup, Diet, Tank Mates, Diseases & More!

When I first started keeping fish, the Flame Angelfish caught my eye due to its vibrant red-orange color, bold black markings, and elegant demeanor. Now that I’ve had experience caring for these beautiful creatures, I’d love to share the essentials for keeping them happy and healthy in a home aquarium.

Flame Angelfish require a tank size of at least 55 gallons, with a temperature range of 72-82°F and a pH range of 8.1-8.4. They are omnivores and need a varied diet of high-quality frozen or live foods such as brine shrimp, mysis shrimp, and spirulina-based foods. They also require a well-lit aquarium with plenty of hiding places and live rock.

A member of the dwarf angelfish family and native to the tropical waters of the Pacific Ocean, the Flame Angelfish (Centropyge loriculus) is a popular species among aquarists. However, they do have their fair share of specific care requirements that should be addressed to maintain their stunning appearance and lively behavior.

In my years of caring for Flame Angelfish, I have found that they thrive best in stable environments, which means paying close attention to factors like water quality, tank size, and feeding habits. Join me as we delve deeper into the world of Flame Angelfish care and learn how to create an aquarium sanctuary that any fish would be proud of.

Species Summary


Flame Angelfish are colorful reef-dwelling fish native to the Central Pacific Ocean near tropical islands like the Johnston Atoll and Marshall Islands.


With appropriate care, these vibrant species typically live for about 5-7 years in home aquariums.


The stunning Flame Angelfish is widely admired for its bright orange color with vertical black stripes and vibrant blue tips on its fins.


As they reach adulthood, Flame Angelfish usually grow to approximately 4 inches in length.

Growth Rate

Generally speaking, Flame Angelfish tend to grow slowly, reaching their full size over a few years.

Behavior & Temperament

Flame Angelfish are known to be curious and bold in their interactions. I once had one that would swim right up to the glass whenever I approached the tank.

Male Vs Female

Sexual dimorphism is not pronounced in this species; however, males are usually slightly larger and might display a small hump on their forehead.

Tank Setup

Tank Size

Flame Angelfish, a small and colorful saltwater fish, require a tank size of at least 20 gallons for a single fish. However, I recommend a 50-60 gallons tank if you plan on having tank mates or multiple angelfish.


Moderate lighting is ideal for your Flame Angelfish. They prefer indirect sunlight, so make sure their tank doesn’t get a lot of direct sunlight exposure.

Filtration & Aeration

A good quality filter and sufficient aeration are crucial for these fish. I like to use a canister filter for a better filtration system, and a protein skimmer to handle organic waste.

  • Canister filter
  • Protein skimmer


Since Flame Angelfish thrive in water temperatures between 72-82°F (22-28°C), a reliable submersible heater is essential. I use an adjustable heater to maintain a consistent temperature.


A mix of live sand and crushed coral works best as a substrate for Flame Angelfish. This allows them to:

  • Dig and bury themselves
  • Search for food naturally


Provide your Flame Angelfish with plenty of hiding spots. I use a combination of:

  • Live rock
  • PVC pipes and caves

This will help them feel secure and reduce their stress.


Flame Angelfish don’t typically destroy live plants, so incorporating marine plants like:

  • Caulerpa
  • Halimeda
  • Chaetomorpha

These will make the tank feel more like their natural habitat and provide additional hiding spots.

Water Quality

Water Temperature

Flame Angelfish thrive in water temperatures of 76-81°F. It’s vital to maintain a stable temperature within this range. I remember when I had my first Flame Angelfish and how sensitive they were to changes in temperature.

Water PH

The ideal pH level for Flame Angelfish is between 8.1-8.4. Maintaining a stable pH is crucial for their health.

Water Hardness

Flame Angelfish prefer water with a hardness level of 8-12 dKH. This helps support their overall health and well-being.

Water Changes

Regular water changes are essential, I recommend changing 20-25% of the water every 2 weeks. This ensures a clean environment for your Flame Angelfish and prevents the buildup of harmful chemicals.

Tank Maintenance

When it comes to Flame Angelfish care, tank maintenance plays a crucial role in keeping your fish happy and healthy. Regularly monitoring and adjusting water parameters should be a top priority.

To maintain high water quality, perform weekly water changes. Replace about 20-25% of the tank water to remove excess waste and replenish essential nutrients. This will help prevent the growth of harmful substances.

Ensure proper filtration to eliminate debris and harmful chemicals. Choosing a high-quality, appropriately sized filter will make a significant difference in water clarity and purity.

Another important aspect is aquascaping. Flame Angelfish love the presence of live rock, which provides natural hiding spots and promotes a sense of security. Arrange these rocks in a way that creates caves and crevices for your angelfish to explore.

Testing water parameters is essential. Monitor the temperature, pH, and salinity closely for any drastic changes. Flame Angelfish prefer a water temperature between 72-78°F, a pH of 8.1-8.4 and specific gravity between 1.020-1.025.

I remember when I first introduced a Flame Angelfish to my tank. I was so excited, but I quickly realized the importance of proper tank maintenance to ensure a healthy environment. With consistency and attention, your Flame Angelfish will thrive!

What To Feed

Flame Angelfish enjoy a diverse diet to maintain good overall health. They prefer a combination of frozen, dried, and live foods, such as:

  • Mysis shrimp
  • Brine shrimp
  • Spirulina
  • Marine algae

It’s essential to provide a variety of food sources to maintain proper nutrition. In my experience, I noticed a positive change in my Flame Angelfish’s behavior when I started incorporating different types of food in their diet.


Feeding your Flame Angelfish 2-3 times per day is recommended to keep them healthy and full of energy. It’s essential to only offer small amounts of food per session, as overfeeding can lead to poor water quality and health issues.

For instance, when I first started keeping Flame Angelfish, I fed them twice a day – once in the morning and once in the evening. This routine made my fish more active and happier.


To keep your Flame Angelfish healthy and thriving, consider these tips:

  • Rotate food types: Changing up their menu prevents boredom and ensures proper nutrition.
  • Monitor feeding sessions: Observe your fish during feedings to ensure they’re eating and to remove any uneaten food.
  • Soak dried food: Before feeding dried food, soak it in water to prevent digestive issues.
  • Use supplements: Enhance your fish’s diet with vitamin and mineral supplements to improve overall health.

Remember to be patient when introducing new foods, as it might take time for your fish to accept them.

Common Diseases


Flame Angelfish are susceptible to a few common diseases that can affect their health and appearance:

  • Ich (White Spot Disease): Caused by a parasite
  • Marine Velvet: Another parasitic infection
  • Flukes: Tiny flatworms that can infest the gills and skin


It’s essential to recognize these symptoms early on:

  • Ich: Small, white dots on the fish’s body
  • Marine Velvet: Gold to rust-colored dusting on the body
  • Flukes: Difficulty breathing, scratching against surfaces, reddening of skin


Treating sick Flame Angelfish requires specific methods:

Ich: Coppersafe medication and raising the water temperature

Marine Velvet: Copper medication and freshwater baths

Flukes: Praziquantel medication


To avoid diseases, follow these preventive measures:

  • Quarantine new fish for at least two weeks
  • Maintain good water quality
  • Feed a nutritious diet

I remember when I first got my Flame Angelfish, I unknowingly introduced a fish with parasites to my tank, and it spread to my angelfish. The quarantine process taught me a valuable lesson in prevention.

Signs Of A Healthy Fish

By keeping an eye on these indicators, you can ensure your Flame Angelfish stays happy and healthy in your care. Remember that regular tank maintenance and balanced diet also play a crucial role in your fish’s well-being.

Signs Your Fish Is Sick

One day, when I went to feed my Flame Angelfish, I noticed something odd: its vibrant colors seemed dull, and it wasn’t swimming with its usual grace. That’s when I realized it was sick. Identifying a sick fish is the first step to ensure its well-being. Here are some common signs to look out for:

  1. Loss of Appetite: A healthy fish should have a good appetite. If your Flame Angelfish is suddenly not eating or eating much less, it can be an early sign of illness.
  2. Discoloration: If your fish’s colors are starting to fade or appear washed out, this could signal a health issue. Healthy Flame Angelfish should maintain their bright orange and black-striped colors.
  3. Lethargy: If your fish isn’t moving around much or seems to be resting more than usual, this might indicate sickness.
  4. Erratic Swimming: Keep an eye on your fish’s swimming patterns. If they begin swimming erratically, heading to the surface constantly or moving in circles, it could be a sign of sickness.
  5. Clamped Fins: Another sign of illness is when a fish clamps its fins close to its body, appearing hunched. This can also be indicative of being uncomfortable or stressed.
  6. External Symptoms: Look out for external symptoms such as spots, lumps, wounds, and white stringy growths. These could signal a disease or infection.

Remember that early detection is crucial for the health of your Flame Angelfish. If you notice any of these signs, consult with an aquatic veterinarian or experienced fishkeeper for guidance on appropriate treatments.


Breeding Setup

When I decided to venture into breeding Flame Angelfish, I made sure to create a separate tank specifically for this purpose. A 20 to 30-gallon tank is ideal, with a slightly higher temperature around 79-82°F.

  1. Water Quality: Ensure water parameters remain stable, with a pH of 8.1-8.4, and a specific gravity of 1.020-1.025.
  2. Decorations: Include PVC pipes, caves, and rocks for hiding places and egg-laying surfaces.

  • Pairing: Introduce the angelfish to the breeding tank and observe their behavior.
  • Mating Rituals: Keep an eye out for displays of courtship, such as male fin flaring and chasing the female.


Once eggs are laid and fertilized, the adult angelfish should be removed from the breeding tank to ensure the safety of the eggs. Follow these key points for egg care:

  • Egg Development: Maintain optimal water conditions to foster healthy development.
  • Larval Stage: Once hatched, feed larvae with freshly hatched brine shrimp and rotifers.
  • Growth Monitoring: Monitor growth, water quality, and behavior daily to ensure progress.
