Rayangrayang

Rayangrayang, also known as the "Rainbow Fish," is a small, vibrant fish native to the freshwater rivers and streams of Southeast Asia, particularly in the Mekong River basin. It is recognized for its striking appearance, with a body that shimmers in a spectrum of colors ranging from red to blue, often with iridescent hues. The fish typically grows to a length of about 10 centimeters (4 inches) and is known for its unique color-changing abilities, which can vary based on its mood, environment, and even the time of day.

Rayangrayang is a popular aquarium fish due to its aesthetic appeal and relatively easy care requirements. It prefers well-oxygenated water with a temperature range of 22-28 degrees Celsius (72-82 degrees Fahrenheit) and a pH level between 6.0 and 7.5. Its diet consists mainly of small insects, worms, and plant matter, which it feeds on by filtering water through its gills.

Despite its popularity in the aquarium trade, the Rayangrayang faces threats from habitat destruction and pollution, which are common issues in the Mekong River basin. Conservation efforts are underway to protect its natural habitat and ensure the survival of this unique and visually striking fish.
