I get what you are saying. I think it comes with the territory. Everyone wants to believe they are doing everything right and people can get very defensive when being told they are not. I've been there done that. lol
And if someone suggest something wrong with the tank size, set up or what have you to someone they take a look at their fish being small and say no they are small I am far from being overstocked. Problem is it doesn't take long before next thing you know they have grown.
I have seen one person have a Bala in a 10 gal
tank, you know where this thread went to. And the person got very defensive and then was going on about when it did out grow the tank they would use their bath tub, you know just stupidity with their answers.
Since joining this forum I have learnt a huge amount that I never knew one being most fish store give very very bad advice. If people could just be open to the help and advice others have for them, take the advice as you may. You can not expect to make a post and not hear some criticism if you are off on something. Ya gotta kind of have a thick skin I found.
It doesn't happen with all threads.
