The brown thing to the left of the duster, not sure what it is, was on the other side of the tank last night. It's about a inch long, I think it's to big to be fish poop from on of my fish.
I couldnt get a better pic last night, so I just grabbed my tongs and pulled it out, I think it may have been fish poop, could a yellow tang or flame hawk make one that big? haha
