Results: Ten of the World's Most Beautiful Fish

Betta fish, also known as Siamese fighting fish, are one of the most popular aquarium fish. In the wild, Bettas don't display the same beautiful colors that we have achieved through selective breeding in aquariums. They are a lot duller, to blend in with their natural habitat – rice paddies and floodplains. Bettas are labyrinth fish meaning they can breathe oxygen directly from the air, as well as taking in oxygen through their gills. Are you familiar with Bettas?

All Angelfish have a beautiful, elegant look to them, but the Regal Angelfish is one of the most beautiful. It is also one of the most difficult to keep in an aquarium. They grow to around 10 inches in length, which means they require a huge tank (a minimum of 100 gallons with plenty of hiding spots). Have you seen a Regal Angelfish before?

Banggai Cardinalfish are native to the Banggai Islands in Indonesia. These elegant, graceful fish are usually found resting between seagrass beds, coral ledges, and sea anemones during the day as they are nocturnal. At night, they will feed in groups of up to 200, on plankton and other small crustaceans. They are very sociable and need to be kept in groups of at least eight to ensure they are happy. Are you aware of these fish?

Flame Angelfish like to live in small groups of around three to seven. Males are likely to fight, so either keep them as a mated pair, or if you're keeping a group – just have one male. All these fish are born female and as they mature, the larger more dominant fish will become male. Have you seen these fish in pet stores before?

Another beautiful fish is the Picasso Triggerfish; also known as the Humuhumu Triggerfish. Just like the artist it is named after, it has a wacky vibrant painted appearance. They are native to the Indo-Pacific Ocean, and in the aquarium, they are an outgoing species that can learn to recognize their owner. Are you familiar with these unique looking fish?
