Food for Regal Tang

[CalHumu]

Does anyone know what I should try feeding my regal tang (paracanthurus hepatus). He's slimmed up ever since I added a unicorn tang which seems to boss it around. I feed it Nori, Formula food, and brine shrimp, but it doesn't seem to be putting on any weight.

Do you actually witness the Regal Tang eating? If the Unicorn Tang is more aggressive, the poor Regal may be hanging back and not really eating.

What size tank do you have and how large are the two tangs?

I do see the Regal eating. It eats pretty much everything I put in there. It's just that the unicorn seems to be quicker and eats more. The unicorn is about 4" and the Regal is about 6". My tank is 100gal.

I was wondering if this could be a nutrition thing. All the other fish in my tank are fairly plump eating mostly formula foods and nori. Does the Regal have any special requirements?
