Paragoniastrea Australensis

The Lesser Star Coral (Paragoniastrea australensis) is a reef-building coral in the family Merulinidae. Its defining feature is that its corallites never fully separate, instead winding together in short, meandering ridges that give the colony a distinctive undulating surface. Found across shallow reefs of the Indo-Pacific, it typically grows into hemispherical colonies in shades of brown or green. Thanks to its hardy nature, it tolerates a range of aquarium conditions reasonably well, making it a popular choice for those new to coral keeping. Its subdued coloring and sturdy form give it a quiet but solid presence in any reef tank.

About Paragoniastrea Australensis

A hardy reef-building coral known for its short, meandering ridges. Found on shallow Indo-Pacific reefs, it forms brown or green hemispherical colonies and suits beginner coral keepers well.

7 things to know before welcoming a Paragoniastrea Australensis

1The Meandering Ridge Pattern
In this species, corallites never fully separate but instead wind together in short, meandering ridges across the colony surface. This undulating pattern is the source of its Japanese name and one of its most distinctive visual features.
2Hardy and Beginner-Friendly
This species is generally considered suitable for beginners thanks to its tolerance of varying water quality and light levels. It's a forgiving choice for those just starting out with coral keeping.
3Preferred Light and Flow
Like many corals in the Merulinidae family, it tends to prefer moderate, stable lighting and gentle water flow rather than intense conditions. When introducing it to a new tank, acclimate it gradually to avoid sudden changes.
4Colonies Reach Tens of Centimeters
Mature colonies can reach several tens of centimeters in diameter. Even a small starter piece can grow steadily over time into an impressive centerpiece.
5Brown or Green Coloring
Colonies typically appear in shades of brown or green, forming a calm, understated presence in the tank. Coloration can vary depending on the individual and its environment.
6Give It Room from Neighbors
Like many reef-building corals, it can sting neighboring colonies that grow too close using its tentacles. Leave adequate spacing between it and other corals, accounting for its eventual size.
7Acclimate Slowly After Arrival
After bringing it home, keep an eye on polyp extension and coloration to check how well it's adjusting. Even though it's a hardy species, take your time with the acclimation process rather than rushing it.
