Biggest Fish in the World In South America, the world’s largest fresh water tropical fish is found in the Amazon River. The Pirarucu can reach lengths up to 16 feet and weigh in up to 500 pounds. This fish is being farmed as a food fish in South America.

Slowest Fish in the World The sea horse holds the honor of being the slowest swimming species on the planet. It swims one foot every 5 minutes. That would be 11 feet every hour.

Most Aggressive and Nasty Fish in the World Many people think that the Black Piranha is the nastiest fish around but it’s not true. The title of the meanest and most aggressive fish goes to the Two Spot Pike Cichlid, Creicichla Lepidota, which kills for sport. Piranhas kill for food.

Most Colorful Fish in the World The most colorful freshwater tropical fish is the Betta. These fish come in many colors ranging from red to blue to yellow. Their long flowing fins and brilliant colors give them a well-deserved first place.

Fish with the Most Personality in the World The Oscar is a very popular aquarium species and it’s due to their great personality. Many aquarists compare the Oscar personality to that of a puppy or a kitten because they can learn simple things like going to their owner and wanting to be petted.
