Labyrinth Fish Paradise FishPhoto © Animal-World: Courtesy David BroughPerhaps the most famous of the Labyrinth tropical fish are the Betta (Siamese Fighting fish) and the Paradise Fish which is called the "founding fish of the aquarium hobby"!The Labyrinth fish are a group known for their ability to breath atmospheric oxygen in the event the water they live in becomes depleted of oxygen or polluted. The organ that allows these fish to breathe oxygen is called the Labyrinth. It is located in the head just behind the gills. The labyrinth looks like a maze which traps air in its' many folds. The oxygen from this air is then absorbed directly into the bloodstream from the labyrinth organ. The word anabantoid is derived from the Greek word meaning to 'travel up'. This is in reference to these fish swimming to the water surface to take a breath of air. Dr. Jungle says, "What curious fish...males build bubble nests!"In an aquarium, you can see the bubble nest as a cluster of bubbles on the top of the water. Once the female lays the eggs, the male will pick them up in his mouth and put them in his bubble nest. The male will continue to guard the eggs until they hatch. See: Breeding Freshwater Fish for more information.
