Overview
What to know before you buy.
Acanthastrea, or 'Acan,' is a popular Large Polyp Stony (LPS) coral with large, fleshy, circular polyps that are fused together in a colony. They are famous for their 'designer' color morphs, which can have rainbows of red, green, blue, and orange. They are semi-aggressive but are known for their powerful feeding response. They should be placed in low-to-moderate light and flow. An interesting fact is their 'invisibility' at night; unlike most LPS, they rarely extend sweeper tentacles, but they will extend short 'feeding' tentacles if they smell food in the water.

Care guide
Everything you need to keep Acanthastrea healthy in a South African setup.
Water parameters
Keep pH 8.1–8.4 and 24–27°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.
Feeding
Acanthastrea is carnivore. Feed a varied diet appropriate for invertebrates — quality flakes, pellets, or frozen foods sized to the mouth.
Behaviour
Acanthastrea is generally semi-aggressive. Observe during feeding and at lights-out for true temperament.
Tankmates
Pair with similarly sized semi-aggressive tankmates in invertebrates. Avoid fin-nippers or species that outgrow this fish.
Breeding
Breeding notes for Acanthastrea vary by line and water chemistry — ask your local shop about proven pairs in SA.
Keeping invertebrates?
Invertebrates read water quality more sensitively than fish — condition and test rather than guess.
