only had my ornate a few days now but already eating well. someone suggested tilapia to me so i got a couple filets cheap at the grocery store and he absolutely loves it. I just cut it into pieces he can take down in one gulp and just drop it somewhere near his hideout area. takes him awhile, he won't just gobble it down right away but after a couple of minutes checking it out he eats it. did the same thing when i gave him some earthworms a couple days ago. I also found that keeping the lights in the tank off and just using the light in the room to illuminate the tank seemed to help with the feeding process. not an expert, new myself to these fish, but maybe this will help
