The Blue Sapphire Damsel is a brilliant marine fish recognised for its intense sapphire-blue colouration and compact, streamlined body. Its vivid colour makes it an eye-catching addition to both reef and fish-only marine aquariums.
This species is relatively hardy and adapts well to aquarium life, making it a popular choice for newer marine aquarists. Like many damselfish, however, it can become territorial and aggressive, particularly in smaller aquariums or when defending a preferred area of rockwork.
Provide plenty of live rock, caves and hiding spaces to help establish territories. It is generally reef safe with corals, although care should be taken when choosing tank mates.

Yes. They are generally reef safe with corals and are unlikely to cause problems with healthy coral colonies.
They can be territorial, particularly once established. Their aggression can be reduced by providing plenty of rockwork and suitable space.
They typically reach around 7–8 cm as adults.
They are omnivores and readily accept marine flakes, pellets, mysis shrimp, brine shrimp and other appropriately sized frozen foods.
It can be challenging. Damselfish may become territorial towards other damsels, especially in smaller aquariums. Careful stocking and plenty of rockwork are recommended.
Live rock or suitable artificial rockwork provides territory, shelter and hiding places and is highly beneficial.
Adding them to a small aquarium with passive fish
Their territorial behaviour can become problematic in confined spaces.
Providing too little rockwork
Caves and crevices help establish territories and reduce constant interaction between fish.
Adding multiple damsels without planning territories
Competition can lead to persistent aggression.
Keeping them with extremely timid tank mates
Peaceful but timid species may become stressed by an established damsel defending its territory.
Overfeeding
Offer appropriately sized portions and maintain good filtration and water quality.

This fish has been through our dedicated quarantine system and is feeding, settled and health-checked before sale. We still recommend acclimating slowly and quarantining new additions at home. Our team is happy to talk you through the right setup - just ask.
