What tank are you upgrading to? Got pics? An achilles is an awesome fish, I hate to see it perish in a 65 gallon. I seen a Achilles freak out in my buddies 125 because he did not have enough room. If the Achilles ends up feeling cramped in the 65g, he will basically kill himself darting all over the tank trying to basically swim his way out of the tank.
BTW, just to play devils advocate. The size of the tank will not stunt a fishes growth. That is a myth, but all the more reason to get a large tank for this fish quick! I would recommend a 240 or 250.
