Pseudacanthicus sp. L380

L380 is almost an enigma, it was a late discovery in the heyday of l-numbers and only very few specimens have ever been collected and exported. It comes from Rio Gurupi, a coastal river in the eastern part of Brazil not far from Belém. It’s not allowed for export from Brazil. It belongs to the same Cactus Pleco group as the fairly similar L185 from Rio Xingu, and P.spinosus, but L380 has a more wormlined pattern of black stripes against a lighter body.


Name: Pseudacanthicus sp.“L380”

Trade names: L380, Gurupi Cactus Pleco

Origin: Rio Gurupi, Brazil.

Maximum TL: 40 cm / 16”

Cactus Plecos are among the most impressive of all Loricariidae. They grow into large, territorial feeding machines that will bring lots of joy and wonder to those who can house them. A diet consisting of meat-based foods is required, so mussels and shrimps are always desired. Additional dry foods with a good vitamin rich content should be added. The water quality must be prime, so a good filtration system, lots of oxygen and regular water changes is necessary for Cactus Plecos to thrive. Elder males become territorial and aggressive towards each other, and even to other Plecos. This means that suitable caves and territorial boundaries should be present, and tank size should not be too small. When all of the above is present, even Pseudacanthicus species can be lured to breed. Males have broader heads and slightly more prominent pectoral fin rays. Females of course show a fatter belly. Up to about 600 eggs are laid in a cave, so the process happens in typical Pleco manner with the male guarding the brood.
