I think its a quasi-bad gamble unless you have the time to take it out of the tank and target feed it. A friend gave me an awesome scoly 2 months back to try and save (apparently, this person did not know that you actually have to feed them). It looked a little worse off than the picture you posted. After about a week, I had made some good progress nursing it back, however the problem is that a sick scoly's mouth tends to "disappear." Long story short, something in the tank had to of messed with it one night because it all of the sudden began to deteriorate at a very rapid rate. Once it began going down hill again, I could not save it. However if you have the money and the time, might as well try!
