Platyfish are small, colorful freshwater fish belonging to the family Poeciliidae. They are native to Central America and are popular in home aquariums due to their vibrant colors and peaceful nature. Platyfish typically grow to about 2 to 3 inches in length and come in various color patterns, including orange, yellow, and blue. These fish are livebearers, meaning they give birth to free-swimming young rather than laying eggs. Platyfish are easy to care for and thrive in community tanks with other peaceful species, making them a great choice for beginner aquarists interested in keeping a diverse aquarium with species like guppies and neon tetras.
