I was in our LFS
today and this guy comes in screaming about how his fish keep dying and he wants new ones not from a chain, the conversation went like this
How often do you change the water and how much?
You mean I actually have to change it? I've had it up a year and there's just green stuff everywhere.
Did you test your water?
Well that's just silly they live in any kind of water.
*The cleark tested the water he brought (not sure why he brought it at this point.)
Umm sir what kind of water do you have?
City that should be the best for them!
Yes but 1st you have to at least dechlorinate it, you'll burn them.
Are you kidding me?
No chlorine will burn us in if we were in the amount they are.
I left at that point affraid I might tell him to at least do some basic things with his fish like put dechlorinator in for them.
