One point on display tanks--yes, they are good. Having a beautiful tank will do much to sell fish. However--don't have things in the tank that you don't/won't sell. One of my favorite LFS has a gorgeous display tank with a huge coral--they won't sell it, and never bring it in for us to buy. Very disappointing.
While I agree that it's important for sales people to work with customers on what fish are appropriate, it is also important to recognize that not all hobbyists want or appreciate this service. If I walk in and say I want a yellow tang and a pair of rams, I am going to be ticked if I start getting the second degree about how these fish can't go in the same tank and that I shouldn't buy them. Acknowledge that some customers are not idiots, just as I acknowledge that some LFS workers are not idiots.
My best advice--offer classes. Have sessions on how to test, how to read test results, how to setup some of the more complex plumbing, etc.
Also--don't think you have to offer 'everything' for sale. If you wouldn't use a product in your own setup, don't offer it for sale. For common plumbing needs, keep a list of where carries the best variety. Same for different substrate options. Not only will it keep your shelves available for fish stuff, it will show your customers that you're equally concerned with them getting their tank done right and making a successful business.
