and when he does Hundreds of little white circles fly out into the water. Is this a parasite or is he shedding something off his suckers. The white circles are not uniform in size they range from very small to about 1/8 inch. They are all perfectly white and perfectly round. If its a Parasite how do I treat it? If its not a parasite is it normal behaviour? Freaking thing is like my kids every time he sneezes I lose 2 years off my life worrying about him.
