Size means nothing for age really. Marbles can hit 12" in 2 years or less if given the right conditions and diet. That's still real young. Anything under 5-6 years old is pretty young for rays. Typically once a male hits about 5-6 years old they want to breed all the time with whatever is available regardless of space, regardless if prego or not. That's why it's been suggested earlier on in the thread it is wise to divide females off.
Previous owner has had him for 4-5 years at least.......idk where u thought he was young in the first place
