He just poops all over his Betta Leaf. When he rests he goes down and lays on these river rocks. He's laying on them as I type this too! Almost as if he's trying to make a statement. At first I thought something was wrong with him... Cuz when I got him a moss ball he'd rub on it some times. Then he'd stare down his moss ball. Now it's like he doesn't like his moss ball any more! It's like the two had an argument or something. Now he lays all over his river rocks. Okay, I guess he doesn't totally hate his Betta leaf because some times he'll swim in circles around it for a bit. Yet again I had to take it out and clean it cuz he poops all over it... He's an odd one this fish.
