Yes, we are. We kind of had the turtles sprung on us, but have fallen in love with them and are now trying to learn everything we can. This website has been a great resource! We're hopefully getting a 150 gallon tank this weekend. Another question: most of the tanks that size on craigslist are reef tanks, and therefore come with a whole bunch of stuff, ie protein skimmer, sump tank, lights, RO filter, etc. Do we need any of that? We found a guy who is willing to sell us just the tank for $175 or everything for $500, but I'd obviously like to save money if possible, and put it towards more turtle-specific items. Also, how much will she grow in a year? If adult female ERCs get to be 16", how long will a 150 gallon tank work for us?
