A close-up photograph taken in Cipanas, Indonesia, captures a single Betta splendens (Siamese fighting fish) suspended in a clear glass jar. The fish displays a light, almost white, head and anterior body, transitioning to a prominent deep red coloration across its scales and fins, particularly the caudal and anal fins. Its dark eye is visible. The jar contains clear water with a line of small bubbles at the water's surface. Reflections are visible on the curved glass of the jar. To the left, a portion of a second, similar clear glass jar is partially visible. The immediate background is blurred, indicating a shallow depth of field, within what appears to be an indoor or sheltered environment.
