About Lamarck's Angelfish
One of the few truly reef-safe angelfish. Picks at zooplankton rather than nipping corals, and the male's elegant tail makes it a centerpiece. Best in larger systems where it has room to cruise the open water column.
Genicanthus lamarck, the blackstriped angelfish or Lamarck's angelfish, is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. It occurs in the Indo-West Pacific region.
Notes from the editors
What it looks like. Slender angelfish body with horizontal black stripes on a white-to-grey background. Males develop elongated tail filaments. One of the few truly elegant swimmers in the angel family.
In your tank. Picks zooplankton from the water column rather than nipping corals — one of the very few reliably reef-safe angelfish. Active swimmer needing open water and 75+ gallons.
Care notes. Pairs (1 male + 1–2 females) work in 100+ gallon systems and display courtship behaviors. Single specimens are fine too. Peaceful for an angel; rarely picks fights.
Sourcing and feeding. Wild-collected from Indo-Pacific reefs ($80–200 depending on size). Omnivore — angelfish-formula foods, mysis, brine, algae.
