Do otocinclus require driftwood?
No. This has been going around for a while, because some people confuse otocinclus needs with some of the “wood catfish” needs, such as the gold nugget pleco. Otocinclus do not suck on the wood to get at the fiber and other materials found therein, but they may enjoy any algae that grows on such driftwood, especially if it reaches near the surface of the tank and receives a lot of light. But otocinclus do not require wood, either in their diet, or in their environment.
