An aquarium is more than just a decorative piece — it’s a vibrant ecosystem teeming with life, beauty, and tranquility. Among the most popular choices for aquarium enthusiasts are tropical fish, known for their vivid colors, fascinating behavior, and diverse species. Whether you’re a beginner or an experienced aquarist, tropical fish can transform your tank into a lively underwater world.
What Are Tropical Fish?
Tropical fish are species that originate from warm, freshwater or marine environments typically found in regions close to the equator. These fish thrive in water temperatures between 24°C and 28°C (75°F to 82°F), which makes heating systems essential in a home aquarium setup.
Tropical fish come in all shapes, sizes, and colors, making them ideal for creating visually stunning aquascapes. They are commonly found in rivers, lakes, and reefs in South America, Africa, Southeast Asia, and the Caribbean.
