Ok- just spent the better part of the a.m. researching this out- from what I have read, about 6-8 articles recommend wood for ANY pleco species, as they enjoy chewing on it, and it is believed to help them with digestion- at the very least, it is just something they enjoy, which aids to their general happiness and quality of life- but some can "live" without it. About 2-3 of them said the only plecos that need driftwood are the ones that actually eat it as a food source (panaques, as AAF had mentioned). Not trying to argue with EITHER of you, or pretend that I am more knowledgeable on the subject than either of you... I'm not. I am just sharing what I read today from multiple sources, and I am sure there are MANY other members on this forum that could tell everyone the same info, and knew it before I did. So, essentially- there are some that NEED to have driftwood, but all of them will LIKE having driftwood, and do get some benefit from it. I, for one, will put it in any of my tanks with plecos, as they do like it, and I would prefer to provide things that aid in their happiness and general quality of life, whether it is essential for survival, or just enjoyed. The same reason I choose to feed fresh veggies to my fish- they can survive on prepared food alone, but, really enjoy fresh foods, so, why not just give it to them? I guess it's all just a matter of personal choice. Again- not trying to argue, make enemies, or start a war. From what I have just researched, RB is right that they do enjoy it & it does provide them some benefits, and AAF is right that it isn't necessarily essential for their bare survival. You both have loads more experience than I do- Knowledge and opinions from both of you are so strongly appreciated. Please, though, can't we all just get along?
