To me, the solution to fish cult stuff is to ignore him and stay with sense and research. If a man can say water's alive and changes itself - that isn't very intelligent. If anyone can follow a man who says that, then there is a lack of seriousness in their thinking.
I'd rather see us build something better, and talk about it in places like here. We need to keep offering scientifically based approaches, and staying with reality. It's mind boggling to see what people will believe sometimes, but if we're going to get anywhere even in our little pastime, we have to keep talking about what matters, what is grounded and what has been researched and developed.
Father Fish refuses to engage in debate. If he's the guy I think he is, he would be presented with 10 sensible arguments against what he said, and would answer the eleventh point, which he had made up himself because it was easy and knew how to respond. He ignored every inconvenient idea, and enjoyed listening to himself only. He seems to have founded his own world after running from every forum and open discussion area because he couldn't hold his own there. It is a cult leader mentality, and the fact he has a following is not encouraging.
The percentage of fishkeeping people who take their hobby seriously is pretty small. I see this as a small window into a vast world of learning. From keeping fish, I've learned about evolution, biodiversity, chemistry, genetics, and a range of related things I might not have encountered in my pay the bills work. The easy lies guys play to the cut flowers from Costco rather than gardening approach to the hobby, and that's a large number of people who may find discussions of what to us is the fun stuff annoying or unnecessarily complicated.
