|Cat-eLog Data Sheet|
|Scientific Name||Batrochoglanis raninus (Valenciennes, 1840)|
|Common Names||Bumblebee Jelly Catfish
Frosch-Fettwels (Germany), Mørk Knurhårsmalle (Denmark)
|Type Locality||Rio La Mana; near Rio de Janeiro, Brazil.|
|Synonym(s)||Pimelodus raninus, Pseudopimelodus acanthochirus, Pseudopimelodus raninus|
|Pronunciation||ra nee nuss|
|Size||200mm or 7.9" SL. Find near, nearer or same sized spp.|
|Identification||The colour pattern is basically a dark brown to black overall with a white to cream colour collar around the nape. A single white to cream coloured marking is also present on the body just above the lateral line and below the dorsal-fin. There is a a light coloured band (which may be incomplete) just fore of the caudal peduncle and a pair of light markings on the caudal peduncle. There is a light marking at the base of the adipose and the tip of the adipose is clear.
Young specimens can be confused with members of Microglanis. Microglanis typically have much more extended light areas and the overall body is not as robust.
|General Remarks||The vast majority of specimens in the aquarium hobby are exported from the Brazilian Amazon and these specimens rarely grow beyond 120 mm. According to Shibatta (an ichthyologist working on Pseudopimelodidae), ''Pseudopimelodidae can be considered the least known family of the naked Neotropical freshwater catfishes.'' Much more work is needed on this family. Given the great amount of size and coloration differences recorded for this ''species,'' and the wide distribution range reported, it is likely that this is either a very variable species or a collection of closely related species with similar cryptic colour patterns.|
|Distribution||The reported distribution is problematic as it includes the Amazon basin, Guyana, French Guiana, and Suriname.

|pH||5.4 - 7.4|
|Temperature||25.0-28.0°C or 77-82.4°F (Show species within this range)|
|Other Parameters||In general, the water should be soft with a gentle amount of current.|
|Feeding||In nature goes stalk-hunting, swallowing prey within its range. Starts feeding on microcrustaceans and aquatic insect larvae, then shifts it diet to fishes of notable size. In the aquarium all foods are accepted greedily. An opportunistic feeder that seems pleased to eat anything that it can fit in its wide mouth. One study of specimens from the wild showed their guts contained mainly seeds of plants growing the water's edge.|
|Furniture||In nature, typically found over silty substrates or amongst concentrations of leaf litter. A variety of hiding places should be provided.|
|Compatibility||This fish will even try to consume larger tankmates that are thin bodied. Lee Finley reported a four inch specimen that ate a seven inch Farlowella even though it could only swallow the first three inches of its prey.
Best kept with tankmates too large and fast to be eaten. Otherwise not an aggressive fish.
|Suggested Tankmates||Medium size and larger tetras, cichlids, and other catfishes.|
|Breeding Reports||There is no breeding report.|
