LOL yes, I have come across the competitive divisions of elitism within this hobby (always after a bigger and bigger tank, compensating for something maybe?) Fortunately its a small minority of hobbyists...they'd be the ones stuck in the kitchen at a house party. You've just got to laugh. ;)
But the vast majority of hobbyists, in my experience, have a wide love for nature whether it be freshwater or salt, and more often than not have many other pets too. I started off very young with cold water, then went to freshwater tropical. As my family is Scottish I was taken to the western highlands at least once a year where there are amazing sand and rockpool beaches, so I got my interest from there also. And being British inevitably I watched a lot of Attenborough on BBC tv, so I have kept insects, amphibians and reptiles as well as always having family dogs. All nature is fascinating, no sense in just restricting yourself to one type.
