Hypancistrus sp. L429


L429 was found by Seidel and Tanke in Rio Jatapu (Rio Uatumá system), Brazil, during an expedition in 2008. It has never been collected, exported or seen since this expedition. We can only hope it will enter our hobby at some point, because it’s a very nice species. It reminds of L4 and L136, but has a more red / brown base colour and yellow spots.


Name: Hypancistrus sp. “L429”

Trade names: L429

Origin: Rio Jatapu, Brazil.

Maximum size: 12 cm / 5''


L429 was found between rocks in water about 1,5 meters deep, in swift current. Water parameters were 29,5 C, pH 7,2, 16 μS/cm. 


They need an aquarium set up consisting of lots of hiding places in the form of rocks, wood and of course specially made caves that suit their measurements. In these the males will eventually guard their offspring. They prefer water that is fairly warm (27-30 C), soft and slightly acidic. Most of all it should be well oxygenated and clean, so a good filtration system and frequent water changes are essential. Among themselves they are fairly peaceful, although males may quarrel for caves and females can sometimes be badly injured or even killed during the breeding-trapping in the male's cave. Males develop longer odontodes on their pectoral fins and on their cheeks, and have broader heads. Hypancistrus are mostly carnivorous, so a selection of crustaceans, insect larvae and fish meat should be offered along with high quality dried foods that also contain some vegetable matter.
