Yellow Tang wasting away
 

My Yellow tang, who's about 3 years old, is slowly wasting away! He's down to where all his bones stand out prominently in his skin. I'd reduced his nori ration for a while because there was plenty of green algae for him to eat, but when I noticed him getting skinny I started feeding him more again. But he's continued to shrink.

There's no other sign of illness, he eats readily, has good color and activity, no red spots, no ick signs, and all the other fish and corals in the tank are looking great. Never seen any aggression from my other fish either.

Water parameters are great.

Salinity: 1.025
Nitrate: undetectable
Phosphate: undetectable
Ca: ~400
Alk: 8-9

Any suggestions? Is there some kind of Tang wasting disease (similar to neon tetra wasting disease)?

Thanks

Phil

What are you feeding other than nori? I feed my tangs mysis, formula one, formula two and nori. Try soaking your tang's food in a vitamin supplement such as Vitam Chem or Selcon.

It might be HLLE (head lateral line erosion).

I alternate Omega One flake, enriched brine shrimp, mussles, red plankton and Mysis.

I've only been feeding red nori, so I picked up some green and brown that I'll alternate with now. Looked for vitamin supplaments, but the LFS's didn't have any decent ones. What they had only had vitamims C and B, and was horribly overpriced.
