The neon tetra is a small, colorful freshwater fish popular in home aquariums. It typically grows to about 1.5 inches long and is known for its vibrant blue and red stripes. These fish are peaceful and thrive in schools, making them a great choice for community tanks. Neon tetras are native to the Amazon River basin in South America, where they inhabit slow-moving waters. They prefer a well-planted environment with dim lighting, which mimics their natural habitat. Caring for neon tetras is relatively easy, as they adapt well to various water conditions, making them ideal for beginner aquarists.
