How many Dispar Anthias should I keep together?

They should be kept in a harem of at least five individuals, consisting of one male and four or more females, to disperse any mild aggression and encourage natural social behaviours.

Why is my new Dispar Anthias hiding and refusing to eat?

This is common in newly acquired anthias due to shipping stress or unfamiliarity with prepared foods. Ensure your tank has peaceful tankmates, plenty of hiding places, and offer living foods like live brine shrimp or copepods to trigger their feeding response.

Will a female Dispar Anthias turn into a male?

Yes. If you purchase a group of all females, the most dominant one will morph into a male over a few weeks, developing the characteristic red dorsal fin and distinct colouration.

Can I keep multiple male Dispar Anthias in the same tank?

It is generally not recommended unless the aquarium is exceptionally large (over 700 litres) with complex rockwork, as males will fight fiercely for dominance and territory.

Are Dispar Anthias safe to keep with corals?

Absolutely. They are strictly planktivorous and will not nip at, consume, or otherwise bother any corals, clams, or decorative invertebrates.

About the Dispar Anthias

The Dispar Anthias is a staple of the marine aquarium hobby, bringing dynamic movement and vibrant coral reef aesthetics to larger tanks. Hailing from the steep, current-swept drop-offs of the Indo-Pacific, these fish naturally form massive aggregations. In the home aquarium, they exhibit a fascinating social hierarchy, typically comprising a brightly coloured dominant male leading a harem of females. Their energetic nature makes them a captivating focal point in any reef display.
