I'm with Cit on this one.. More tanks doesn't mean more knowledge.. it just means you take your work home with you. I'm down to 7 tanks atm.. and work in a LFS. I get asked a question at least weekly about something I don't know. And often ask MFK for help with my own personal collection. And reccomend people to this site as well. I'm also constantly on this site researching info for stock we have in the store that I may only know a little about. A good LFS employee will turn away a sale, if they know it's not in the best interest of the fish. A bad one will tell you whatever you want to hear. And Sometimes people just have bad info.
It is your tank, and your decision as stated.
