Yes, quite dramatically. Juveniles have a black body with yellow bands, but as they grow they develop the adult coloring of golden-brown with blue stripes and a yellow tail.

The Bluestriped Angelfish is not listed under CITES. There are no other species-specific legal restrictions to be aware of.

Bluestriped Angelfish

The Bluestriped Angelfish is a striking marine species native to Japanese coastal waters, its golden-brown body crossed by vivid blue stripes and finished with a bright yellow tail. Juveniles look completely different from adults, sporting a black body banded with yellow, making their transformation especially rewarding to watch. Growing to a maximum of about 22 cm, it makes a real visual statement in an established aquarium. Newly introduced individuals tend to be shy and hide among the rockwork, but with time they settle in, become confident, and respond well to their keeper. As a species best suited to experienced aquarists, it fits keepers who can maintain careful water quality and a stable tank environment.

About Bluestriped Angelfish

7 things to know before welcoming a Bluestriped Angelfish

1Suited to Experienced Keepers
The Bluestriped Angelfish is rated as suitable for experienced aquarists. It is sensitive to water quality fluctuations, so consistent maintenance and avoiding sudden environmental changes are essential. We recommend building marine fishkeeping experience before bringing one home.
2Shy at First
Right after being introduced to a new tank, this fish tends to hide and may stay out of sight for a while. Avoid chasing it and provide plenty of live rock for shelter so it can settle in at its own pace. Once acclimated, it will gradually become more visible and active.
3Dramatic Color Change with Growth
Juveniles have a black body with yellow bands, but as they mature the coloring transforms into the adult pattern of golden-brown with blue stripes. Watching this gradual transformation over time is one of the fish's biggest appeals.
4Grows to About 22 cm
The Bluestriped Angelfish is a medium-sized angelfish that can reach approximately 22 cm at full size. Prepare a sufficiently large aquarium in advance so it has plenty of room to swim comfortably as it grows.
5Native to Southern Japan's Rocky Reefs
This angelfish is native to Japanese coastal waters, particularly the rocky reefs of southern Japan, and favors environments rich in rocky crevices. Arranging live rock to create hiding spots and territory in the aquarium helps it feel more secure.
6Becomes Easier to Keep Once Settled
The initial wariness fades once the fish has settled into its environment, after which it tends to be calm and stable. Many individuals become responsive at feeding time, making for an engaging fish once acclimated.
7Preparing Your Tank in Advance
Since this is a species best suited to experienced keepers, it's important to have a tank with stable water quality and temperature ready before bringing one home. Also check in advance that live rock hiding spots and any tankmates will be compatible.
