Can I Keep a Brittle Star in a Mixed Reef Tank?

Quick Answer

Yes—many brittle stars are reef-safe scavengers, but avoid large predatory species and feed lightly so they don't starve.

Most common brittle stars can do well in mixed reefs and help clean up leftover food.

  • Choose reef-safe species from trusted vendors.
  • Provide rockwork and crevices for hiding.
  • Target feed small meaty foods occasionally.
  • Avoid very large green brittle stars known to prey on fish.

You can browse compatible inverts in the ReefBay shop and monitor your tank’s feeding/stocking balance in the ReefBay app.
