Lyretail Anthias Care: A Comprehensive Guide to Keeping and Enjoying These Beautiful FishFishkeeping is an incredibly rewarding hobby, and it comes with a lot of responsibility. You must provide your aquatic pets with a healthy and stable environment to thrive in.

Among the many fish species available for aquariums is the Lyretail Anthias. These beautiful fish require specific care and attention to ensure that they are healthy and happy.

In this article, we will explore everything you need to know about lyretail anthias care, from their origins and habitat to their temperament and diet. Origins and Habitat:

The Lyretail Anthias, scientific name Pseudanthias squamipinnis, belongs to the Pseudanthias genus and is indigenous to the Indo-West Pacific Ocean.

These fish can be found in the waters around the Red Sea and the coral reefs in the Pacific Ocean. In their natural habitat, they feed on zooplankton and are often found in harem communities, where one male will care for several females.

Hermaphroditism and Sexual Dimorphism:

Lyretail Anthias are protogynous hermaphrodites, which means that they are born female and can change into males as they mature. The male and female appearances of Lyretail Anthias are quite different.

Males are typically larger than females and have elongated dorsal spines. Female Lyretail Anthias are generally smaller with less vibrant colors.

Males tend to have more purples and yellows on their body, while females are typically more of a yellow or orange tone. Tank Requirements:

Lyretail Anthias require a minimum aquarium size of 50 gallons, with 75 gallons being the recommended size.

They need plenty of open swimming space, and the tank must be set up in a reef tank setting to mimic their natural habitat. Lyretail Anthias, like most fish, require stability in their water parameters.

Therefore, regular water changes are essential to maintain water quality. Temperament and Aggression:

Lyretail Anthias are an active fish species, and males typically exhibit more aggressive behavior than females.

Males will compete for food and territorial space when kept together. Therefore, it is best to keep one male per tank, or a ratio of one male to several females.

If multiple males are kept in the same tank, they may become aggressive towards each other, which can lead to injury or death. Reef-Safe and Tankmates:

Lyretail Anthias are considered reef-safe, meaning that they will not damage or disturb any sessile invertebrates in the tank.

They make great additions to community tanks, but tankmates must be chosen carefully. Avoid adding aggressive fish species like damsels or triggerfish to the tank, as they may harass and attack your Lyretail Anthias.

Instead, select community fish species that are known to work well together. Diet:

Lyretail Anthias are carnivorous, and they require a diet consisting mostly of meaty foods to thrive.

Feed them a variety of live, frozen, and freeze-dried foods, with a high planktivore content. These foods include copepods, calanoid and cyclopoid, krill, Mysis shrimp, among others.

High-quality flake foods should also be part of their diet to provide them with essential nutrients. Common Diseases:

Lyretail Anthias are prone to Uronema, a ciliate parasite that can cause symptoms like rapid breathing, loss of color, lethargy, and poor appetite.

Therefore, quarantine all new fish before adding them to the tank and treat with a freshwater dip. Use products like metronidazole or medicated food to treat the parasite should it develop in your aquarium.


In this article, we have explored everything you need to know about lyretail anthias care. From their origins and habitat to their temperament and diet, we hope that this guide has been informative and helpful.

Remember to provide your Lyretail Anthias with a stable and healthy environment, feed them a nutritious diet, and choose tankmates carefully. With proper care and attention, your Lyretail Anthias will thrive in your aquarium for years to come.

Lyretail Anthias Tank Size and Population: The Importance of Providing Adequate Space and Social Dynamics

The Lyretail Anthias is an elegant and vibrant fish that makes a stunning addition to any aquarium. However, providing these fish with proper living conditions is crucial for their health and longevity.

In this article, we will explore Lyretail Anthias tank size and population, including the minimum tank size required, gender and population dynamics, and the importance of social behavior and shoaling. Minimum Tank Size:

Lyretail Anthias are known for their active swimming behavior and require plenty of open swimming space.

A minimum of 125 gallons is recommended to accommodate their spatial needs. This large tank size provides plenty of room for the fish to move around and maintain their territory.

To enhance their natural habitat, include plenty of live rock in the aquarium to provide shelter and hiding spots. Population Size and Gender:

Lyretail Anthias population size depends on factors like their age, size, and gender.

Juvenile female Lyretail Anthias can be kept in groups of 5-6, although this population should decrease as these fish mature. When they reach sexual maturity, it is essential to limit the population to one dominant female with several males or a harem of several females with a dominant male.

When fish are kept in groups, it is essential to maintain a proper male-to-female ratio (1:3-5 males: females) to reduce competition and aggression. Lyretail Anthias exhibits social behavior and prefer to be in groups.

In all-female groups, there is often a dominant female who will govern the group responses to other females. In the presence of a dominant male, the subordinate males will often be female in appearance, allowing for a more social and interactive population.

This dynamic is essential for maintaining peace and harmony in the aquarium setting. Feeding Habits:

Lyretail Anthias have carnivorous feeding habits and require a diet consisting primarily of planktonic organisms found in the water column, like zooplankton.

In the aquarium setting, these fish require a high-protein diet readily available in floating foods. To keep them healthy and thriving, it is important to provide a broad range of foods, including live, frozen, and freeze-dried supplements.

Feeding Recommendations:

Lyretail Anthias should be fed 2-3 times a day, with the primary diet consisting of copepods. Copepods are an essential component of these fish’s diet and should be included as a staple component to alleviate any dietary deficiency.

You can supplement their diet with high-quality flake food or other dry formulations like Benereef Reef Food. Live and frozen foods like Mysis shrimp and brine shrimp are also great for adding nutritional variety.

Plankton Availability:

In their natural habitat, Lyretail Anthias have access to a variety of planktonic organisms. In the aquarium setting, this natural fauna should be supplemented with additional food types like Reef Frenzy as a way to provide them with a balanced diet.

Using these additional food types like zooplankton will give the fish a more natural habitat, provide additional nutrition, and enhance the quality of life for the population. Conclusion:

Providing adequate tank size, proper gender dynamics, and social behavior is crucial for the health and happiness of Lyretail Anthias.

These fish require ample living space, a balanced and protein-rich diet, and appropriate social settings and shoaling. If kept in an environment that meets these requirements, Lyretail Anthias will thrive and create a stunning addition to any aquarium.

Lyretail Anthias: Common Diseases and Prevention Strategies

Lyretail Anthias is a popular fish that demands proper care and maintenance to thrive in an aquarium setting. Keeping your Lyretail Anthias healthy is essential, and the first step to achieving this is by preventing diseases.

In this article, we will discuss common diseases, their symptoms, and prevention strategies that will save you the hassle of dealing with unhealthy fish. Uronema and Symptoms:

Uronema is a free-living ciliate parasite that commonly affects Lyretail Anthias and other saltwater fish.

The parasite derives its energy from the fish host by attaching itself to the fish’s external mucous layer and triggering an immune response. Typical symptoms of Uronema include raised red bumps, abrasions, open sores, discoloration, and constant flashing.

Infected fish may also show signs of lethargy, loss of appetite, and labored or heavy breathing. Quarantine Importance:

Quarantining new fish before introducing them to your main tank is an essential preventive measure.

This protects other inhabitants of the aquarium by identifying potential pathogens before they have the chance to contaminate the entire tank. Uronema, in particular, is known to devastate entire aquariums of fish, which makes quarantine even more critical.

It gives the observer a chance to identify and treat infected fish before introducing them into a healthy population. Medication:

If you suspect that one of your fish may have Uronema, it is essential to act quickly with medication to prevent further contamination.

One way to medicate your Lyretail Anthias is by using a freshwater dip to lower the parasite’s load on the fish’s surface before introducing them to a medicated tank. Metronidazole is often used as a treatment for Uronema and can be administered in the form of medicated food or a bath.

However, when medicated directly in the tank, the medication may affect the healthy bacteria, so it’s advisable to use it sparingly. Hardiness and Adaptation:

Lyretail Anthias is known for their hardiness, but this does not exclude them from adapting to new environments.

Like any saltwater fish, Lyretail Anthias require stable conditions, and the acclimation to a new environment needs to be gradual to prevent stress. If Lyretail Anthias is placed in a new tank with massive changes in parameters like water temperature, salinity, or ph levels, it may experience stress, which could lead to a weakened immune system and vulnerability to parasite attacks.


Lyretail Anthias is known to be one of the hardiest species of fish, but prevention strategies and identifying symptoms early enough are essential to keep them healthy. Quarantine procedures, medication, and being cautious with their adaptation process will help keep your Lyretail Anthias thrive in your aquarium.

Remember to provide the best possible environment for your Lyretail Anthias, including good filtration, water quality, and adequate feeding practices. By implementing preventive strategies and providing the best care possible, you can maintain a healthy Lyretail Anthias population.

In conclusion, Lyretail Anthias care requires attention to detail and a focus on maintaining stable, healthy living conditions. The article covered vital topics, including the fish’s origins and habitat, hermaphroditism, tank requirements, temperament, population size and gender, feeding habits, and common diseases.

By providing adequate space and the right environment, feeding a nutritionally balanced diet, monitoring for diseases like Uronema and preventing contamination, and being careful during the acclimation process, Lyretail Anthias can thrive in an aquarium setting. These beautiful fish require the right care and attention to achieve their full potential, and by following the guidelines outlined in this article, fish enthusiasts can enjoy a stunning and healthy fish population.
