By Cachoeira da Lontra, Rio Curuá (Brazil), above a monumental waterfall, Ingo Seidel & Co. found 8 specimens of L428 between the rocks in strong current. It has never been collected for the ornamental trade, and currently it’s not present in our hobby.
Name: Hypancistrus sp. “L428”
Trade names: L428
Origin: Rio Curuá, Brazil.
Maximum size: 12 cm / 5''
L428 reminds a little of L270 from Rio Curua-Una (on the southside of the Amazonas) and L316 from Rio Jari, but has a different pattern in the fins and on the head.
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.
