popular aquarium fish species

Popular aquarium fish include species like guppies, bettas, tetras, and goldfish. Guppies are small, colorful, and easy to care for, making them ideal for beginners. Bettas, or Siamese fighting fish, are vibrant and can live alone; males are territorial. Tetras are tiny, school-loving fish that add lively movement to tanks. Goldfish, known for their bright orange color and graceful swimming, require more space and filtration. Each species has unique needs for water quality, temperature, and diet, but all can bring vibrant life and beauty to a home aquarium when cared for properly.
