A long, narrow tube-shaped log — and that slim tube is exactly the shape cave-dwelling plecos look for. Unlike a bulky den, the Scape Log gives a pleco a snug, body-length tunnel that closely matches how it shelters and holds territory in the wild, while its slender driftwood profile slots neatly into an aquascape. It works as both functional pleco shelter and a natural hardscape line in a planted layout. Which fish it's for Plecos — bristlenose (Ancistrus), Hypancistrus, Peckoltia and others that like a tube Catfish and loaches that rest in enclosed runs Shrimp and small fish using it as cover How to use Rinse before use. Lay it on the substrate in a shaded, low-flow spot; bed it in slightly so it sits stable. For plecos, choose a log the fish can nearly fill.
