The Coral Beauty Angelfish, known in Japanese as Ruriyakko, is a small angelfish prized for its striking gradient of purple and orange coloring. Relatively hardy among small angelfish, it readily accepts prepared foods, making it a popular entry point for anyone new to keeping angelfish. Reaching about 8 to 10 cm as an adult, it stays compact, but a tank of 100 L or more is recommended, and keeping it alone is the basic rule. While individual temperament can vary, many specimens get along well with other fish, which is part of why this species remains a favorite among both beginners and experienced aquarists alike.

7 things to know before welcoming a Coral Beauty Angelfish
1Best Kept Alone
Coral Beauty Angelfish can be territorial toward their own species and other angelfish of the same genus. Keeping more than one in the same tank often leads to conflict, so single specimen keeping is generally recommended. Building a live rock formation that can serve as its territory helps it settle in.
2May Nip at Coral
Some individual angelfish may nibble at coral or invertebrates. If introducing one into an SPS-dominant reef tank, it's important to observe behavior closely and proceed with caution.
3Easy to Wean onto Pellets
As an omnivore that feeds on prepared foods, frozen foods, and algae, it tends to take readily to commercial pellet food. This flexibility in diet makes daily feeding management relatively straightforward.
4Provide Live Rock Hiding Spots
This species likes to retreat into rock crevices and coral gaps, so arranging ample live rock to create hiding spots is recommended. A secure environment helps reduce stress.
5Avoid Sudden Water Changes
Although hardy and easy to keep, this species can be sensitive to sudden shifts in temperature or specific gravity. Take time with drip acclimation and maintain stable water parameters to support long-term health.
6Plan Tank Size for Adult Size
Adults grow to about 8 to 10 cm. Even if the fish is small at the time of purchase, it's wise to plan for a tank with enough swimming space to accommodate its full adult size.
7A Long-Term Companion
With a lifespan of around 5 to 10 years, this species can be a relatively long-term companion among marine fish. It's a good idea to have a stable long-term setup and maintenance routine in place before bringing one home.
