It's a good thing to talk about one's frustration. And there's room for that overhere. But even a frustration can be put in the open in a non-harsh way. Looking at all the replies within this topic, we can say that we do agree on that. In my opinion, people are allowed to make mistakes. As long as they'll learn from it, it it will be okay. To use the word "experienced", I'm an experienced aquarist as well. But I won't be hypocrite to say that all I've done throughout the years in this field has been flawless. Also I've learned from my mistakes. We also have to accept that experiences can be different among aquarists. With a lot of issues, there's not just one solution. Being passionate about aquaristics, does not mean that one is entitled to be harsh on somebody else when a mistake has been made. I've read it quite often at other forums and even on Facebook, that people use their passion as a justification to be so hard on somebody. And oh yes for sure, there are enough people who put themselves on a pedestal as being the ultimate fish expert or aquarium expert. I myself am a seasoned aquarist but even I still learn every single day. I would rather use the term "well-experienced aquarist" rather than "expert'. For this still says, that one is still not at the top of the mountain.
And yes, there are indeed people who just won't accept a good advice. if that goes on and on, I'd stop to engage with such people. For that does indicate that they're not willing to change their view on things. And yes, that might cost lives of fish but one can not stop that from happening unless you know where those people live (
). And for sure, it would be better for them to change their hobby... As long as there are people walking around on this globe, difference in opinion will always be there...
