I agree, but I think it is a little unrealistic for him to look up every fish he gets in. My problems were with pbass and dats - two groups of fish where individual species can be very difficult to tell apart. It's not like he labeled a clown loach as a silver arowana here. Yes, I was disappointed that I didn't recieve exactly what I ordered and will be sure to have positive i.d.'s in the future, but looking at the big picture, I personally can't blame them for not knowing these subtle differences, and I am not looking to burn any bridges or hold any grudges for this. I advised him on what they should be labeled as, he heard me out, and he changed their names on the inventory list.
No reason to get your panties all in a bunch about this. After all, I am the one who was affected by this, not you, and I'm past it.
