I took a fish back to the shop today that can grow to over 4 feet. I knew he would get big, but was told a maximum of 2 feet and wanting to believe this I had bought him. But now I'm sitting here thinking about it and I'm worried I may have done the wrong thing. Won't he most likely get purchased by someone else who can't adequately house him? I have capacity for a 7X2 tank in the future and I was just thinking that if this is better than what the person who buys him would provide, he may have been better off with me
