Lashing out? Please. I don't want to de-rail the OP's thread any more, but I want to address this.
Here is your attempt to "call out" Duane. He just recently posted an informative thread about soft water cichlids in hard water, and vice versa. If you feel you are well informed, and wanted to debate about the topic, that would have been the place to do it. Many people did actually have great debates in that thread; don't see your posts anywhere. Posting it here in response to advice given, is just an attempt to "discredit" his advice, while you offer 0 to the original poster yourself. If instead of doing it like this, you had said something like "actually, fish from soft water regions can do quite well in hard water, here are the reasons I believe so, here are my experiences, etc." I would have no problem with it. Instead you wrote a smug one-sentence post which offers nothing to the conversation but to discredit someone else, who you have no business attempting to discredit.
And the tone of this post, again with 0 supporting information added, is probably what irked me. Now I've explained myself, I won't be addressing this in this thread anymore.
