This high-resolution image features a male Betta splendens with a brilliant turquoise-blue body and vivid crimson-red caudal and dorsal fins that fan out dramatically. The fin rays are sharply defined, revealing delicate translucency and gradient coloration from deep red to pale lavender at the edges. The fish’s flared gill covers and alert posture suggest active display behavior, typical during courtship or territorial assertion.
