Physical Characteristics

In this section, we explore the distinctive features of the Lemonpeel Angelfish that contribute to its recognition and appeal.

Coloration and Markings

The Lemonpeel Angelfish (Centropyge flavissima) is aptly named for its bright yellow body that closely resembles the color of a lemon. This vibrant yellow angelfish is also characterized by a distinct blue edge on its gill cover, also known as the operculum, and a compelling blue ring around the eyes. The vividness of its hues makes it a striking presence in any marine setup.

Anatomy and Size

As a species of dwarf angelfish, they are considered small in size when compared to other marine angelfish. We can typically observe an adult Lemonpeel Angelfish reaching up to 5.5 inches in length. This size classification makes them suitable for smaller marine aquariums. They display the traditional angelfish body shape with a laterally compressed form, a singular dorsal fin, and rounded caudal fins. Additionally, these fish possess a small anal fin which, like other marine ray-finned fish, aids in their swimming agility and stability in the water.

Behavior and Compatibility

In discussing the Lemonpeel Angelfish’s behavior and compatibility, we must acknowledge their semi-aggressive temperament and tendencies towards territoriality, especially regarding live rock formations which they use as hiding places. Their behavior and interaction with tank mates are influenced by these characteristics.


The Lemonpeel Angelfish, a vibrant member of the family Pomacanthidae, exhibits a bold and active temperament. They tend to establish territories within the aquarium, often around live rock structures that provide essential hiding spaces. Their behavior can be somewhat unpredictable as they may show aggression towards species with similar colors or body shapes. It’s essential to provide ample space for them to roam and establish personal boundaries to discourage aggressive tendencies.

  • Aggression Level: Semi-aggressive
  • Territorial: Yes, particularly around live rock

Tank Mate Selection

When selecting tank mates for the Lemonpeel Angelfish, we must choose species that can coexist with a semi-aggressive fish. It is advisable to avoid housing them with overly passive or smaller fish that could easily become targets. Similarly, fish that bear a resemblance to the Lemonpeel, in color or form, may provoke aggressive behavior due to territorial instincts.

  • Compatible Tank Mates:
    • Large, non-aggressive fish
    • Fish with dissimilar coloration and body shape
  • Incompatible Tank Mates:
    • Small, docile species
    • Fish with similar appearance to the Lemonpeel Angelfish

Providing the Lemonpeel Angelfish with an adequate environment and carefully selected tank mates can result in a harmonious aquarium.

Diet and Feeding

In caring for Lemonpeel Angelfish, ensuring a varied and nutritionally adequate diet is critical to their health and vibrancy.

Nutritional Requirements

We must provide Lemonpeel Angelfish with a mix of both animal and plant-based food sources. They are omnivores with a strong penchant for marine algae. A well-balanced diet for these fish should consist of:

  • Marine algae: A staple that fulfills their herbivorous needs.
  • Mysis shrimp: High in protein and essential fats.
  • Brine shrimp: Often used as a food source, but less nutritious than mysis shrimp.
  • Clams and shaved shrimp: Offer additional protein and mimic their natural feeding behaviors.

In captivity, Lemonpeel Angelfish thrive on processed foods that are spirulina enriched, as these provide a plant component to their diet that is rich in essential vitamins and minerals.

Feeding Habits

We find that Lemonpeel Angelfish adapt well to captive feeding schedules. They should be fed small amounts several times a day to mimic their natural foraging behavior, which includes:

  • Grazing on algae: Throughout daylight hours on surfaces such as live rocks and tank walls.
  • Consuming live foods: Such as brine shrimp, mysid shrimp, and clams, offering crucial nutrients.

Inclusion of seaweed, in particular, can be an excellent supplement to their diets, typically attached to a clip inside the aquarium. This method encourages foraging and provides enrichment.

Aquarium Care and Maintenance

In our experience, maintaining a Lemonpeel Angelfish in an aquarium requires attentiveness to its environment and health. We’ll discuss essential information on tank conditions and practices to keep these fish thriving.

Tank Setup

When setting up a tank, we consider size and water composition paramount. Lemonpeel Angelfish thrive in a saltwater environment. Here is a brief rundown of the key tank requirements:

  • Tank Size: We recommend a minimum tank size of 55 gallons to provide ample space for swimming and territorial behavior.
  • Water Parameters:
    • Temperature: Should be maintained between 72°F and 82°F (22°C to 28°C) for optimal comfort.
    • pH Levels: Aim for a pH range of 8.1 to 8.4.
    • Specific Gravity: This should be between 1.021 and 1.025 to mimic natural seawater.

Water conditions should be stable, with regular monitoring and adjustments as necessary. We often use testing kits to monitor these parameters. Frequent water changes are essential to managing nitrate levels and preventing the buildup of harmful contaminants.
