One species, four l-numbers! This was never considered one of the spectacular Hypancistrus species, with it's dark grey body sprinkled with light spots. A nice look in it's own right, but certainly one of the most common designs among l-numbers. So it makes this species slightly anonymous in the vast selection of alternatives for aquarists worldwide. It's still a great beginners pleco, and like most Hypancistrus it has it's appeal nonetheless!
Name: Hypancistrus sp.L4/5/28/73
Trade names: Angelicus Pleco, L4, L5, L28, L73
Origin: Rio Tocantins (L4/5), Guamá (L28), Rio do Pará (L73), Brazil.
Maximum size: 12 cm / 5''
This species occurs in the surrounding rivers of the city of Belém, Brazil. The spots on it's body varies according to age, with bigger spots found in younger specimens. The variation in spot size and the fact that they are found in different rivers have led to them being given several l-numbers.
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.
