Armoured catfish

There are about 50 different species of armored fish. Their native place is in South American water bodies but now they have also adapted themselves with the streams and canals of Florida as well. The fish is peaceful in nature and as a result of which it can stay along with other native fish of Florida. The fish is of small sized variety and unlike other types of cat fish this fish only can grow up till 2 foot in wild. The fish prefers to stay in moving waters of streams rather than stagnant water. It also has the capacity to crawl in the ground with the aid of the pectoral fins for quite a long distance in land. Like the fish varieties of gur, bowfish or lungfish this specie of fish has a special secondary breathing system. With the aid of this special adaptation of the breathing system the fish is able to swallow oxygen from the open air which is then take up with the fine capillary blood vessels located in the walls of the intestines. In wild the fish feed themselves in aquatic animals like the small sized carrions and water fleas. The fish has another special adaptation having the mouth ending more like a sucker. Since the fish stays mainly in moving waters the suckers actually helps the fish to cling to rock surfaces at the time of heavy flowing water current. While clicking to the rocks the fish can also feed on the algae that grow on the surfaces of the stones.The fish is mainly nocturnal in nature and prefers to come out and search out their food from the river bottoms at night. Very limited information is avail regarding the breeding techniques of the fish. Even if they are kept in aquarium they are hardly seen to be breeding. In wild a female fish lays around 250 numbers of eggs at a time and deposit them on rock surface and the eggs are found to be hatching with in a week.
