Oscar still alive?

[Terrorizing Cichlid]

I have a 3in. O for 2 months now it it doesn't seem to eat. It would just chew and spit (out the mouth) the food out. I have had 3 Os in the past but none did anything like this. I feed it hikari gold, omega one pellets and omega one brine and it does this to all. The only time it actually ate was a month ago when I used freezed dried shrimp and a week ago when I feed a piece of nightcrawler.
Water chem (amon & nitrite 0 and nitrate 10ppm) with bi-weekly water changes
Is it just being stubborn? And how long can a young fish go without eating? Or is it eating a portion of the chewed up food and just spiting the majority of the food? It is out swimming and even rearranging the plants, which I took out. When I vac gravel I see strains of solid brown waste; it can't be the other fish's waste b/c the ralph cat's waste is red (so no bullying). Coloring is an intense orange which was the same as when I got it.

Fish need very little food to survive, sounds like he's being a sook, but 2 months also seems quite excessive.

If he fully ate the freeze dried shrimp and worm/nightcrawler then I'd consider looking to change foods or just stop feeding him altogether for a week and see if he'll gulf down the pellets, which I'm presuming are an appropriate size for him (Hikari should be Mini or Baby (The tiny ones) sized for a 3" Oscar)

thank-you for your reply.
No it's the med pelletes which I fed all my fishes when they were 3inches( sal, JD, and 3 O) and they took it.
I'll go grab some sample aqueon food samples if it'll take that.
