Yellow tang losing weight

[joebeagle]

Over the last few weeks my yellow tang has been losing weight. I've been feeding tetra color marine flakes to the other fish (of which he was partaking), seaweed salad, and mysis shrimp. As of late he has not been eating well and has been losing weight. I noticed it was recommened to add some garlic to the seaweed salad. It spiked his interest but he is still not eating like he used to. I was at the lfs today and one of the employees suggested adding romaine lettuce. Here's my questions:

1) How should the lettuce be prepared?

2) What else can I do to help him out before I lose him?

I have checked all my water parameters and they all check out fine. No other fish are being affected.

What is the salinity? Do you see any black specks on the fish? Have you every treated it with praziquantel or a freshwater dip? Try some frozen spirulina and Formula-Two. Some tangs need to be fed several times a day. If your fish just isn't eating as much as it used to then the first thing I would suspect is some sort of parasite is making it feel poorly. Do you quarantine all new fish? When was the last addition to the tank?
