As mentioned in that sticky, I have raised & bred some of the most bloat prone fish on the planet over the years, and never had any bloat issues, even with young fish on diets that exceeded 50% protein. (NLS Grow) Overfeeding was also mentioned in that thread, it's easy for people to blame brands and/or protein levels when they are overfeeding their fish on a daily basis. I get "bloated" too when I get carried away at the dinner table. Stress comes in many forms, some people recognize that early on in their fish keeping careers, others never do and simply look elsewhere to lay the blame.
