"panaques" are raspers btw... steer clear away from plecos that have rasping teeth. If you value your tank and wood/driftwood. hypan's are generalay carnivores. L128 blue phantoms seem to like a lil of everything, but i have ponly seen them eat alge off from driftwood. A large panaque pleco with a rasping mouth will dissolve driftwood only in a matter of time. They also like to grab ahold of discus and eat theri slime coat etc... You must do the research and find the right l# for your set up. Id look for L183"s aka white seam bushynose, also aka starlight/galexy bushynose plecos. they dont get huge, they eat a lil of everything and they wouldnt degrade your driftwood. or a L128 blue phantom or a L200 green Phantom. You may be able to find these locally in your lfs.
good luck
