Pleco cave - Natural

Built for breeders: Twenty caves to set up a full breeding rack or colony tank in one go. Give every male his own defensible tube, maximise the number of viable spawning sites, and keep territorial conflict low across a high-density system — the way a working pleco farm runs its racks.

A breeding tool, not decor. This is the classic straight-tube cave — a tight, enclosed tunnel with a bark-like texture that reads like the rock and root crevices cave-spawning plecos claim in the wild.

The tube shape does real work. A male backs in and blocks the entrance with his own body, where he can guard the clutch and steer a steady flow of water over the eggs. That defensible, body-tight fit is what convinces a male to commit to a cave and spawn — and it's why we use this exact style on our own breeding systems.

A male should be able to nearly fill the entrance — that snug fit matters more than extra space.

Sizing and species

Choose the size by the body of your fish:

• Small (14 × 4.3 × 4.3 cm) — Hypancistrus and Peckoltia, and other plecos growing to around 10 cm: Zebra (L046), L134, L136, L236, L173, L174
• Medium (13.5 × 5 × 4.5 cm) — bristlenose (Ancistrus) such as L181, L183, L144, and similar-bodied fish up to ~10 cm
• Large (20 × 6.5 × 6 cm) — larger, mature plecos that need more room

How to use

Rinse before adding to the tank. Set it on the substrate, or bury it slightly so it sits stable, in a low-flow, shaded spot where plecos feel secure. For breeding, give each male his own cave and space them apart so fish can hold separate territories.
