Update on my fish

Just wanted to give an update on my Yellow Tang and 2 Clowns, i think i figured out the problem, yesterday morning, the tang was still being a bully to my clowns, but i talked with a friend of mine who's been doing saltwater fish for a few years now, he told me that the food supply might be low, so i went and bought some frozen cubes for them to eat, and i added that yesterday afternoon, and they all ate it, and the rest of the day the clowns never swam away from the tang, they were all over the tank the rest of the day, this morning they were still all swimming together, with no issues, so im thinking adding more rock like i did and adding that cube helped, cause my tang is no longer an issue and he seems healthy and for people who are saying hes gonna get to big for my tank, that might be so but i have friends with bigger tanks who can take him off my hands when that time comes.
