Thanks for the replies. I feed it 2-3x a day with mixtures of mostly frozen food.
I tried Nori but this one won't eat it for some reason.
I do have culerpa growing on the tank and it like those. It eats the tender shoots when they come up.
Those bumps on it's tummy appears when it eats a lot of culerpa, but disappear when it's all digested and back to smooth looking tummy.
I read a few comments that the fish don't look healthy, can I ask the it doesn't look healthy?
It's been happy, from what I can tell, and eats a lot and never developed any type of illness in the last 7 years. It's very yellow, no sign of lateral line disease, which I see often in captive tangs.
Anyway, here are a couple more photos of it and the some of it's tank mates.
Never had any aggression with this fish since it's the only tang in the tank and all of her tank mates are very different shape and size, and colors.
