The Loricariinae are a subfamily of South American catfish that have adapted to life in fast-flowing streams and rivers. In German, the fish are often referred to as witch catfish .
features
The Loricariinae are characterized by their slender, elongated body shape, their long and flattened caudal fin stalk and the lack of an adipose fin . They have only one row of bone plates on each side of the body. They are very variable in body shape, morphology of the sucking mouth and teeth. Many species show pronounced sexual dimorphism , which is reflected in the increase in the size of the pectoral fin rays of the males and on the lips and the structure of the teeth. Some species are toothless.
Way of life
From their way of life, two ecotypes can be distinguished within the Loricariinae, sand dwellers and those living on stones and wood substrates. The first group eats an omnivorous and / or carnivorous diet and often has a specially designed mouth with many lips to feel food in the sandy bottom of the water. The loricarines that live on stones or wood have a very powerful mouth to hold on to and feed on algae as a growth eater. All Loricariinae practice brood care. Among them there are substrate spawners , cave breeders and mouth or lip breeders .
