As a store owner if someone is in the store that i havent seen before and they say they want a fish i alway's ask them if they know the general care for the fish. If they do we talk about outher thing's (there tank, there plains, ect ect). If they don't know i give them the genual care of the fish ( what he eat's, how big he grow's, and recomended tank size and tank mates). I willingly spend countless hour's with custimers just talking about fish to make them more educated about the fish even if i don't make a sale im still happy knowing that that person is walking out of the store with more knolage then when they walked in.
