The Threadfin Butterflyfish is instantly recognizable by its white body crossed with fine diagonal chevron stripes and the thread-like filament trailing from the rear of its dorsal fin. Among butterflyfish, it's considered hardy and takes readily to prepared foods, making it a beginner-friendly choice for those new to marine fishkeeping. Adults can grow up to 25cm, giving them a confident presence in the tank. That said, they have a habit of nipping at coral polyps, so they're better suited to fish-only setups than reef tanks. Active, engaging swimmers, they're often kept alone so their striking pattern can really stand out.

關於絲蝴蝶魚
Threadfin Butterflyfish: a hardy, beginner-friendly marine fish with striking chevron stripes and a filament fin extension, growing up to 25cm. Not reef-safe due to coral-nipping.
迎接絲蝴蝶魚前需要了解的7件事
1Hardy and Easy to Feed
Among butterflyfish, this species is considered relatively hardy and adapts well to prepared foods. It's regarded as beginner-friendly, making it a good entry point for those new to marine fishkeeping.
2Not Reef-Safe
Because it tends to nip at coral polyps, it isn't suitable for reef tanks. Consider a fish-only setup instead.
3Grows Up to 25cm
Adults can reach up to 25cm in length. Plan for a tank with enough swimming space to accommodate their eventual size.
4Striking Chevron Pattern
Its white body is marked with fine diagonal chevron stripes, and a thread-like filament extends from the rear of the dorsal fin — both distinctive features of this species.
5Best Kept Alone
Individuals of the same species tend to become territorial and may fight, so they're best kept singly. If considering tankmates, check compatibility carefully first.
6Stable Water Quality Matters
Like most marine fish, they're sensitive to sudden changes in water quality. Regular water changes and monitoring help keep conditions stable.
7Provide Hiding Spots
Rockwork or live rock hiding spots help them feel secure. They may spend more time sheltering while adjusting to a new environment.
