Hey! So I have a new tank all ready for a new bottom feeder. This one is a Hypostomus plecostomus bottom feeder suckermouth armoured pleco catfish (commonly referred to as the "common pleco"). I was just wondering, is it absolutely necessary for them to have driftwood or can they just feed on the algae and the occasional algae wafer? I know they do like to munch on it but is it 100% necessary or just recommended? Either way, I'll buy some driftwood, but if it's just a slight decoration or maybe just a treat they I might not. Thanks for any input.
