i bought a jack when he was under half inch. literally. I feed him a variety of foods he got really dark and blue and if very beautiful and he has a personality like no other, and he know his master when i walk up to the tank.
i have a jag and a jd, both similar, i prefer the jag tho. for a single fish i would suggest a flowerhorn, they can b beautiful and theyr very fun to watch and grow up from small
