informed employees, knowing what you stock an the parms of the fishies needs are, knowing what fish can live with others, how big etc etc , most people in the hobby will know what they are looking for, an thus will be there choice to purchase , the key in what i'm saying is to have knowledge to tell to the people that are just starting out, if you know what you are talking about , an they rely on what you are telling them, an they have no problems they will believe what you are telling them , an THEY will be back, keep an get quailty stock, unlike the big chain stores can or will do, (IE tonight i seen neon tetra disesae in a tank with there stock to sell, so that means the chain stores are to big to control this , or don't care what the sell in the name of a dollar) Be able to order anything a person needs or wants at a fair price. like what i found at frank & pegs a piece of driftwood for $8.57 ( which i think they made a mistake) , then when i was in need of some substrate that was 35 a bag everywhere , i went there to buy it, an drove farther to get, they where fair to me , SO I REMEMBER THAT!!!!!!!!!!!
