About Schooling Bannerfish
The schooling bannerfish — a Moorish-idol lookalike that's dramatically easier to keep. Best in groups of 3–5 in a larger tank. Not reliably reef-safe (will sample LPS and zoanthids), so think of this as a fish-only-with-live-rock species.
The schooling bannerfish, also known as the false moorish idol, is a marine ray-finned fish, a butterflyfish from the family Chaetodontidae. It is native to the Indo-Pacific area.
Notes from the editors
What it looks like. Tall, laterally compressed body with bold black-and-white vertical bands and yellow accents. Visually nearly identical to the Moorish idol but dramatically easier to keep.
In your tank. Schooling species — best in groups of 3–5 in larger tanks (100+ gallons). Not reliably reef-safe; will sample LPS polyps and zoanthids. Treat as fish-only-with-live-rock.
Care notes. Peaceful with most tankmates. Add the full group simultaneously. Active swimmer needing open water.
Sourcing and feeding. Wild-collected from Indo-Pacific reefs; widely available ($50–100 each). Omnivore with strong meaty preference — mysis, brine, prepared marine foods.
Care info is a starting point, not a guarantee. Individual specimens, water chemistry, and tankmate dynamics vary. Verify against multiple sources and adjust to what you observe. See our terms & disclaimers.
