Stripe-tacular!

Dive deep beneath the waves surrounding the Banggai Islands in Indonesia and meet the Banggai cardinalfish. Cardinalfish can grow up to 8 centimetres and have tiny shimmery bodies with black vertical stripes and white-edged fins, which help them disguise. Unlike some finned creatures that migrate long distances, these pint-sized fish inhabit a small world, rarely straying far from their local reefs.
