Mandarin - To add or not to add?

[onesocksarah]

Hi, I have a similarly stocked tank and just added a Mandarin 10 days ago. My sixline and regal tang can be bullies at times and in fact gave another new addition (bicolor dottyback) a hard time. However, they have absolutely left the Mandarin alone. Because of his slow moving/hunting habit he seems to be no threat to anyone in terms of food and habitat. While he is safe I fear that I do not have enough food source in an established 70gallon tank to keep him well fed. I have a refugium, chaeto and a great breeding ground for copepods but he seems to either feed very methodically and slow or is lacking food. I even fed live brine the last few days and his feeding habit remains very slow. He came in very fat, adapted very easily and seems happy enough so only time will tell.
