Datasheet

General Description

The Threespot Angelfish, scientifically known as Apolemichthys trimaculatus, belongs to the Pomacanthidae family. It is categorized under the Apolemichthys genus, containing medium-sized Angelfish with varying needs. These colorful fish are recognized for their stunning appearance but can be challenging to maintain in captivity due to their specific dietary requirements. This species is not deemed reef-safe and is unsuitable for coral aquariums due to their tendency to prey on soft corals and large polyp stone corals.

Aquarium Suitability

The Threespot Angelfish demands experienced aquarists for proper care, as they require specialized food for their continued health and wellbeing. Keeping these fish can be difficult, especially for beginners, as meeting their dietary needs is crucial for their survival. It is recommended to acclimatize them as juveniles to aquarium conditions for better adjustment, particularly because very small individuals can be delicate.

Care and Hardiness

With an average hardiness level, the Threespot Angelfish acclimatizes best when introduced at a young age. These fish are shy and docile, necessitating hiding spots in the aquarium, especially when newly added. Due to their peculiar food requirements, providing a varied diet is essential for their optimal health. Maintaining a well-established tank with algae for grazing purposes is beneficial for their diet.

Reef Suitability

This Angelfish species is not considered reef-safe due to their tendency to consume various invertebrates, including soft corals and large polyp stone corals. They may exhibit aggression towards similar species, making it crucial to carefully curate tank mates to prevent conflicts.

Aquarium Setup

When setting up an aquarium for Threespot Angelfish, it is advisable to provide plenty of hiding places, especially during the initial acclimatization period. Building a mixed coral aquarium with suitable corals like Hammer corals, Bubble corals, and Star polyps can help minimize the risk of these fish consuming coral species. Ensuring a spacious tank with ample hiding spots and high water quality is essential for their well-being.

Behaviour

Threespot Angelfish are known to be shy and docile, requiring caution when housed with more aggressive tank mates. They might display territorial behavior, especially towards similar species, emphasizing the need for careful monitoring and appropriate tank arrangements.

Feeding and Diet

The diet of Threespot Angelfish primarily consists of larger polyp stone corals, other invertebrates, and soft corals. Feeding them a varied diet that includes large crustaceans, macroalgae, microalgae, small crustaceans, and sponges is crucial for their nutritional requirements and overall health.

Habitat and Distribution

These Angelfish species are found in the Indo-West Pacific region, spanning from East Africa to Samoa and from southern Japan to Australia. They thrive in diverse marine environments but are more suited to experienced aquarists who can cater to their specific dietary needs and care requirements.
