The pink kissing gourami, scientifically known as Helostoma temminckii, is a freshwater fish native to Southeast Asia. They are known for their unique "kissing" behavior, where they press their lips together, often in territorial displays between males, though it's not an actual act of affection. These fish are generally peaceful and can grow to be quite large, up to 12 inches (30 cm) in captivity. They have a lifespan of about 5-8 years.
