In Rio Jatapu, Brazil, a group of German aquarists discovered L489 during an expedition in 2016. There it lives syntopic with Hypancistrus sp. L429. There’s a resemblance to H.margaritatus (L404) from Rio Tacutu and H.cf.margaritatus (L136) from Rio Negro, but these riversystems are not connected to the Rio Jatapu. To the best of my knowledge, L489 was brought to Germany but never established in the hobby. No commercial fish collecting occurs in Rio Jatapu, which prevents new imports of L489 from happening.
Facts:
Name: Hypancistrus sp.
Trade names: L489
Origin: Rio Jatapu, Brazil
Maximum size: 14 cm / 6”
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 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 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.
