My fish tank has a fake log that was moved to the middle left of tank last week. That area happens to be right under where most of my fish like to hang out. Ever since then, I noticed it has been accumulating a lot of poop on it. Is it ok if I let the poop accumulate on the log until my next cleaning (which will be in 3 days), or should I take it out and clean it off? I will relocate the log again in my next cleaning. I just worry about the poop hanging out in the open like that vs being buried in the rocks, like maybe the fish might try to eat it thinking it's food?
