 -it never has bubbles and barely any tenticles to speak of
 -its stalk is healthy and its able to move quickly around the rocks and attach very well
 
 I'm very concerned with whats going on and I would apreciate any tips as to what could have caused these changes and how I can caux him back into what he was.

 How big is your tank? What light are you using?

 I hope your SG is 1.0252 

 BTW , what device do you use to measure SG to get an accuracy of 0.0002

 I do RO water top offs in the morning and at night to keep salt levels in check

 Do you measure any of above parameters? especially strontium, Iodide? Fuel (amino acid) may not do reef tanks any good.
Back to the RBTA, does it have any tentacles left? Are the tentacles sticky (i.e. when you feed it food, does it stick to the tentacles?) If they are still sticky, try to feed it. If it doesn't eat and hiding in a place with little light, your RBTA is no hope. I suggest you getting it out and giving it to a more experience reefer. my $0.02.
