LVT I live in the Twin Cities very close to you, I am originally from Roseville. I started Marine fish keeping in the past 6 months and have found it very rewarding. Just as you have seen from the reactions of other members on here, we all would love to see you trying out marine fish keeping with a larger tank, I started out with a 29 gallon tall, and found it to be a good starter tank if you don't want to get too large, but a 55 gallon would be an ideal size with very managable filtration and wouldn't totally kill your pocket book. I have been upgrading to larger tanks, and have many tanks that I am getting rid of, let me know if you are interested, we'll get you a great start at Marine fish keeping! Good luck!
My email is superedge88@yahoo.com if you are interested in a larger tank.
