The problem arises when you walk into your LFS and "See the most amazing fish", but you don't know much about it.
Then what do you do? You could rummage through the shelves of books trying to find some info - or you ask the staff.
I - for one - don't want to have to do all of the research myself - digging through book after book while standing in the store.
They know the types of fish they order - just provide the info on the ones they carry. As long as the advice is correct it really does not have to be extremely detailed. But knowing whether it should be kept alone, in pairs, in schools, what temps., food, size, aggression, etc. should not be difficult to provide. Wouldn't they have to know those things in order to care of the fish in the store???????
I can't believe that we can walk into a garden store and find out everything there is to know about growing a certain plant - and it is all on a tiny little plastic sheet stuck in the dirt. But when you go to the LFS all you get is FW, SW, BW - and sometimes that is not right.
Sorry - ranting again.
