don't have to measure him if you are going to take him out, might freak him out and stress him.
I would just put a measurement tap or ruler next to the tank and wait until it swims close enough to give you an idea.
a 120g would be nice. I see a little chimple is staring to form on the lower jaw. does he rub against the glass a lot?
