I never claimed to know everything, in fact I know very little in regards to the vast amount of information available. The difference is I take commonly held truths and attempt to apply them to my fish keeping. On another note, why are you being so standoffish? I offered my opinion, you don't like it? Ignore it? Simple huh? To call me a know it all and attempt to project your own attitude towards fish keeping on me is laughable. Keep giving your fish "good enough" care and living conditions, guess I shouldn't really care.
