Thanks for your replies. I did not think it was pregnant but I did not want to think infection. It was really weird because what looked like eggs or some sort of ball thing did not stay attached for long and instead through out the day the ball shifted from one spot on the body to another in a rocking motion. In the beginning there were 3 balls, then soon after posting one of the balls (the one behind his left gill plate) must have fallen off because I could no longer see it. The little fellow did not look like he was in any discomfort; his behavior was very normal. Then I pulled out my camera phone to attempt to photograph the "ball" in a more precise fashion only to discover that the "balls" were no longer there. I was really confused and since then I have not noticed any more irregularities. The white balls - when they were attached - seemed as if they were held on by and clear slimy coat, but I have not noticed anything since
