All assigned numbers:
blue panaque, L239
South America: upper Rio Orinoco, Amazonas, Venezuela.
Suitable for aquariums, but can be very aggressive against other armor catfish, other Finnish Blue in particular. This species is fairly territorial namely: finding and retaining caves, suitable for building a nest, is usually the stumbling block. More than a Blue Fin 'Panaque "in a small tank could result in injury or death of one or more fish, although in a large tank with many decorations they could reside together.
The minimum tank size for a single fish is 80x30x30cm. For a group of 3-4 fish a well decorated aquarium 100x40x40cm is required.
Sexing and Breeding:
Given the large suckermouth, filled with many very small teeth, this species is a "Aufwuchs" eater. Aufwuchs is the organic layer, part plant, partly consisting of small organisms (scale insects, freshwater sponges, small insects, insect eggs and larvae, and plankton), which forms on submerged surfaces, and which by this catfish is grazed.
Once acclimatized, the Blue Fin 'Panaque' will in most cases eat both meat food (shrimp, krill, mussels, mosquito larvae, blood worms) and vegetable food (blanched vegetables, tablets, algae, and, to the dismay of many aquarists, also aquarium plants) feeding.
Temp 25-30c PH 5.5-7.5
This strikingly colored catfish prefers a tank with many hiding places dimmed, in the form of plants, drift wood, rocks and / or artificial caves. For multiple Blue Panaques, or those mixed with other bottom dwellers, an aquarium of 120x50cm is required, since the species can be territorial with a lack of suitable shelters or overcrowded. The Blue Fin Panaque can behave aggressively towards other bottom dwellers. If the only occupant in the bottom tank is a tank of 100x40cm. Juveniles can easily be temporarily kept in smaller aquariums, as long as there are enough shelters.
This species is the best in soft, slightly acidic to neutral water, rich with oxygen and strong current. A strong filter is important, as these fish are can produce a lot of waste.

The Blue Fin 'Panaque' is known as a difficult to acclimatize catfish: many of these fish are found dead during the first months due to stress and malnutrition.
Another problem for newly imported specimens, the degradation of the bacterial intestinal flora, which is affected by disrupted transportation (due to digestive problems and a significantly reduced uptake of, especially during the first weeks, extremely important nutrients). Commercially available fish must have a minimum number of weeks in quarantine at the importer / dealer for reasonable survival guarantee. Fish with sunken eyes and abdomen will usually die within a few weeks. Therefore save you a lot of frustration, observe the fish before purchase to avoid disappointment.
Once home it is strongly recommended the fish again for several weeks in a quarantine aquarium to keep the animal quiet to get used to life in prison and the local water values. Also during this period he should be observed feeding - depending on the offered food - red to dark-colored thin wisps solid stool should be found, indicating that he is eating well. In addition, if certain foods are what will and will not be accepted. Once eating well, active and alert, and looks healthy (good color, bulging belly, slightly bulging, bright eyes), he may be moved to a bigger aquarium.
Despite its misleading trade name, the Blue Fin 'Panaque is not part of the genus Panaque - it has little or nothing in common with these large, wood-eating catfishes. The question to which this species or genus belongs was done in 2009, when ichthyologist Lujan, Arce & Armbruster this species scientifically described as Baryancistrus beggini.
But the last word seems not talked about yet, since not everyone seems convinced that the Blue Fin 'Panaque' actually belongs to that family.
