The image shows a close-up of a small fish in a glass jar. The fish appears to be a type of aquatic animal, possibly a seahorse, with a long, slender body and a pointed head. It is swimming in a body of water, which is a light blue color. The water is clear and there are small bubbles visible on the surface. The background is blurred, but it seems like the jar is sitting on a table or countertop. The text on the image reads "Bacterial streaming (bacterial wilt disease)".
