Relevant Information:

Description: Entomocorus radiosus is diagnosed by the unique combination of a long anal-fin base, 18–22 branched anal-fin rays, unpigmented pectoral and pelvic fins, and caudal fin hyaline, with distal half of dorsal and ventral lobes pigmented with black. Specimens were collected from a creek and in wide open environments, as river channels and bays of the upper Rio Paraguay basin in the periodically flooded areas known as the Pantanal. Known to be a zooplanktivore which also eats insects. Stomach contents predominantly has microcrustaceans (cladocerans, copepods and ostracods); insects (ephemeropterans, coleopterans and hemipterans); and/or small amounts of water mites, rotifers, fish scales, bryozoans, unidentified eggs, detritus, and sand. Reproduction: This species spawns in July and August in the period of maximal annual flooding. Sexual Differences: The males have elongated ventral fins and the dorsal becomes long and curved. Aquarium Care: Inactive during the day so would need feeding at night but as aquarists know this family will find food that has been left during daytime feedings. Diet: Not a fussy eater. Mosquito larvae, artemia, flakefood, tablet and pellet foods.
