I have a planted tank with 3 large pieces of driftwood and 2 smaller ones. I have 3 bristlenose plecos that cleans all the algae from them, but the one big piece in the middle of the tank has an area at the top that they don't touch and I'm not sure why. It's easily accessible but for some reason they don't go there. Does anybody know why that might be?
Question about my bristlenose pleco..

Good point maybe.Same type of algae?
If it's kinda high up there they are probably just too lazy...
Are you seeing dark green algae on the top of that driftwood? If so, that algae is from being close to the light and has to be scraped off, the plecos cannot suck that type of algae off. They probably do go over that section of wood but can't clean off what you're seeing. If the plecos wouldn't go up there because the light was too close to them when it's on, when the light is off...they would surely visit there!
It's the same type of algae that is on the other pieces of wood, and I have a deep tank so it's not close to the light. The wood is the same height as the other pieces. Just seems weird to me.
I have seen BNs eat pretty much any type of green or brown algae (diatoms). If its something completely different that might be why they are avoiding it.
