What type of BTA is this and is it healthy?

Just a few questions to watch for.
- Is it growing or just inflating in an attempt to expose more of it's xoanthellae to the available light source?
- Is it eating or is it spitting the food back out when you're not looking?
- With regard to light, who's to say what is or is not enough? There are over 300 different strains of xoanthellae that all have different lighting needs that are hosted by hundreds of different types of cnidarians. I've seen a friend keep an RBTA under a single normal output light for years.
With regard to color, my personal observation has been that when an anemone bleaches that it usually keeps its color tint but gets lighter. An anemone that is white when it's bleached will usually be brown when it recovers. Some white anemones (usually sebae) are white naturally.

- Believe none of what you hear and only half of what you see.
 
Along the lines of BTA color loss...is there anything that can cause it to lose its tint, but not the symbiotic xoanthellae (that spelling seems off but...) ? I have one which I thought was "white" (really a golden brown color) but its actually starting to look more green, especially when the halides are off and just the blues are on.

Green is a pretty common tint in any cnidarian. Particularly the brown ones. Think of the tint as being like a sunscreen. It's not unlike people having melanocites. Some people have a lot more than others but all can adjust the amount to fit the intensity of the sun where they live.
The bluer the light, the more the pigments tend to show up. The more red the light is the more darker the xoanthellae. Dana Riddle has done some interesting experiments on this topic.
