Hi! I have a 56 gallon tank with no fish right now. I bought the tank about 2 years ago and only did small schooling freshwater fish. My dad had a 55 salt water tank when i was a kid and it was beautiful. You just don't get that beauty with freshwater. I would love to do saltwater but it seems really expensive. Any ideas for stocking, saving $, and/or your suggestion if i should do fresh water or salt would be greatly appreciated. Thanks so much for your help in advance!
