You know, there are 2 different ways to correct someone when they make a mistake...one is to make them feel 2" tall and like a total moron. The other is to perhaps show a pic of a GT and FM in comparison to your fish and politely explain the differences. Which way would you prefer to be corrected?
Did you know everything when you bought your first cichlid? Did you do anything worthy of being called an idiot? I know I did but fortunately people were polite enough to correct me in a much better way, hence my love of cichlids grew even further and I continued to post online and learn what I've learned.
I'm just sayin...
