Description
The fish in the image, commonly known as a Silver Moony or Fingerfish (*Monodactylus argenteus*), is a shimmering, disc-shaped fish with a silvery body and often yellow fins. While juveniles can be found in freshwater, they require brackish to full marine conditions as they mature. This schooling species thrives in groups and can reach a significant size.
