eating habit

I've had my gator gar for about 1 year already. A couple of weeks ago, I noticed it would spit out everything I gave it. I figured it might just be full. I've been trying to feed it every few days to see if it would start eating again, but the behavior has not changed. It's been almost two weeks...

It's already more than a year since I got my rtcs. Healthy fish, bite my hands a few times, 4 of them. But I've read somewhere (one of the thread in monsterfishkeeper) that these cats will slow down their eating after reach 2'+ and aged more than a year. The problem is that my cats won't stop...
