 Cat-eLog Data Sheet | |
|---|---|
| Scientific Name | Hypophthalmus fimbriatus Kner, 1858 |
| Common Name | Dolphin Catfish |
| Type Locality | Rio Negro, South America. |
| Pronunciation | hi pop thal muss |
| Etymology | (Greek)Hypo=Under + (Greek)opthalmos=eye. |
| Species Information | |
| Identification | Hypophthalmus fimbriatus is quite distinct from its congeners because of its greatly elongate, flat and thick mental barbels. No other known catfish species has as large mental barbels, relative to body length. It also has a deeply forked caudal fin. |
| Sexing | Unknown. |
| General Remarks | It has been hypothesized that the large barbels are sensory organs that, when projected forward, allow the fish to 'feel' about olfactorily, and perhaps electrically, for Zooplankton concentrations. Once Zooplankton concentrations are found, they are sucked in and the larger cladocerans are sieved out by the gillrakers. |

| IUCN Red List Category | Not Evaluated |
| Husbandry Information | |
| Feeding | Studies show H. fimbriatus is mostly zooplanktivorous, and that cladocerans (water fleas) are the principal zooplankton eaten. It is believed that H. fimbriatus is a filter feeder through the sieving action of its gillrakers. User data. |
| Breeding | Unreported in the aquarium. |
