Platies are small, colorful freshwater fish belonging to the family Poeciliidae. They are popular in home aquariums due to their vibrant colors and peaceful nature. Platies typically grow to about 2 to 3 inches in length and come in various color patterns, including orange, yellow, and black. They thrive in warm water and prefer a well-planted tank with plenty of swimming space. These fish are livebearers, meaning they give birth to free-swimming young rather than laying eggs. Platies are social creatures and do well in groups, making them an excellent choice for community tanks. They are also relatively easy to care for, making them suitable for beginner aquarists.
