Fish loosing scales??
So i have a goldfish about 5-6 inches long looks like a feeder that survived from a year ago or so but anyways i noticed that a lot of his scales are missing, he acts normal he still has his daily routine of picking up every single rock in my 135 and spitting it out so i dunno what to think! any thoughts and yes all water parameters are normal.

What else is in this 135g tank with the goldfish? Could it be damage from bumping into objects? Also, I'm not sure what normal is with water parameters. We need a number in PPM for ammonia, nitrite and nitrate levels. Hopefully you're doing regular water changes to keep nitrates not to exceed ~20ppm.
