Chalceus Macrolepidotus Curimatidae Chilodus

Body shapes and sizes vary considerably, from 2 in (5 cm) long pencilfishes to the stocky African distichodusspecies, which measure 16 in (41 cm). Piranhas and pacus are muscular and heavily built to facilitate the tearing of flesh or fruits. Other characins , in contrast, may persistently eat aquarium plants. Characins have sharp teeth in the jaws and mos have an extra fin, known as the adipose fin, on the back. The family contains many popular fishes, including the tetras, of which the brilliant Neon and Cardinal Tetras are prime examples.Most characins spawn using egg-scattering methods. The male may have tiny hooks on the anal fin to hold the female against him during spawning. The eggs are adhesive and usually lodge among plants. One exception is theSplashing Tetra, which deposits eggs on a firm surface out of the water, to protect them from the attentions of aquatic predators
