The aquarium industry is full of people who absolutely think they’re right when it comes to a particular topic. On the forums and in the blogosphere, there is always an expert, and that usually translates to a few heated discussions and hurt feelings. While we can certainly understand the frustrations when dealing with folks who choose not to heed advice or listen to more seasoned hobbyists, we all have to remember that this is a hobby, a pasttime. If a random aquarist disagrees with you on a forum, who cares? I know that we give out advice that isn’t always well received, and sometimes we are flat out wrong. So, if you’re a forum goer, keep the conversations clean and pleasant.
