Care notes
Remarkably twig-like camouflage — extremely slender and angular. Rasping algae-eater like a Pleco but far more delicate. Sensitive to poor water quality and low oxygen. Needs well-oxygenated, clean water. Fascinating and unusual bottom dweller.
Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
