Overview

The Poma Angel, also known as the Grey Angelfish or Black-headed Angelfish, is a mid-sized Chaetodontoplus species with a muted grey-to-brown body, a darker head, and a fine yellow trim along the tail and fin edges. It doesn't have the bold, saturated colouration of some other angelfish, but its subtle patterning and calm presence make it an appealing choice for keepers wanting something a little different from the flashier reef angels.

As a true Chaetodontoplus angelfish it sits between the smaller Centropyge dwarf angels and the large Pomacanthus species in both size and care demands, needing more swimming room than a pygmy angel but without quite the scale or feeding challenges of a true large angel.

It's a reasonably hardy species once settled, though as with most mid-sized angelfish, sourcing a specimen that's already feeding confidently makes a real difference to how smoothly it transitions into a new tank.

Compatibility

Poma Angels can be territorial toward other angelfish, particularly similarly sized or shaped species, and are generally best kept as the only angelfish in small to medium tanks. They are usually peaceful toward unrelated community fish such as tangs, wrasses, and gobies.

Reef compatibility is inconsistent between individuals — some leave stony and soft coral alone entirely, while others will pick at LPS polyps, zoanthids, or clam mantles, so this species is rated reef safe with caution rather than fully safe.

Health & quarantine

A minimum four-week quarantine is recommended, with close attention to appetite and breathing in the first two weeks, as this species can be slower than some angelfish to settle and begin feeding confidently after import. Buying from a supplier who has already confirmed the fish is eating well significantly reduces the risk of prolonged stress-related decline. Once established and feeding on a varied diet, it's a reasonably resilient, long-lived aquarium fish.

Frequently asked questions

Is the Poma Angel reef safe?
It's rated reef safe with caution — some individuals leave coral entirely alone while others will nip at LPS, zoanthids or clam mantles.
How big does a Poma Angel get?
Around 18cm at full adult size, larger than dwarf angels but more manageable than a true large angelfish.
What tank size does a Poma Angel need?
At least 400 litres, given its mid-sized adult length and need for swimming room.
Why won't my new Poma Angel eat nori or pellets straight away?
This is fairly common after import — try meatier frozen foods like mysis first, and introduce nori and pellets gradually as the fish settles.
Can I keep a Poma Angel with other angelfish?
Generally not recommended in a modest tank — it will usually not tolerate another similarly sized angelfish nearby.
