Hypancistrus zebra
Volta Grande of the Rio Xingu, Brazil · rapids
Brazil banned wild export, so Canadian stock is tank-bred. Clean, even stripes where L236 are broken and patchy.

Xingu and Tapajós basins, Brazil · rapids
Big white spots on black with white fin edges. Striking, but big and territorial.
Leporacanthicus triactis
Orinoco, Venezuela · rapids
Eats snails and holds a cave firmly. Can be rough with smaller plecos.
Hypancistrus inspector
Upper Rio Negro and Casiquiare, Venezuela and Brazil · rapids
Bigger, sparser white spots than L201, and a bigger fish overall.
Unknown origin · rapids
Large white spots on black. A big snail-eater that grows to about 30 cm, so it needs a large tank.
Leporacanthicus galaxias
Rio Tocantins and nearby Pará rivers, Brazil · rapids
The vampire pleco. Beautiful, but it gets large and bullies smaller plecos.
