Demo
Save the Little Fish demo · Medium, 30–40 gal · strong current, like a river or rapids · running 1140 days · shared October 2026
A bare-bottom 40-gallon breeder set up for one thing: zebra plecos spawning. Warm (29–30°C), soft and spotless water, a powerhead pushing current over eight slate and clay caves, and only one Hypancistrus species, so every fry is pure L046.
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.

Two males, four females. The dominant male holds the end cave and fans the eggs for about a week.
Every species is comfortable in this range.
A rough estimate based on adult body size and tank volume.
One per fish plus two spares, so nobody has to fight for a spot.
Some of these fish come from fast rivers. Run a powerhead along the bottom for flow and oxygen.
Size and stocking checks use a typical tank of the size you picked. Add the real length and volume for a sharper answer.
Care data for L046 is estimated or taken from the genus, not yet checked against a source.
