First an Aro now a Dat you have been bit by the ]v[onster fish bug.
Feeding: I agree with those who said try and get him on pellets as soon as possible but there's no need to starve him just yet. I've had fish that where hard to get onto pellets but Indo's weren't one of them(knock on wood). IME they adapted to pellets readily if the other fish where vigorous eaters but not intimidating to the Dat. Feeding alone you can try sneaking in some pellets that have been soaked and softened in the worms and drop them in together and he may accidentally eat some pellets and begin recognizing them as food.
Stability: There's been many a debate on how to get a Dat stable but I've had success with all those I've kept so far(knock on wood) so I can give my opinion on why. I've never kept more then one Dat at a time except when mixing. For instance I once had 3 AT's and one Indo and all where stable. I'd say my success was a combination of things.
One was the Dat's where the dominant fish in a tank full of cichlids. I believe this inspired him to go full bars in response to cichlid displays of colors and aggression. Two I believe if you keep more then one Dat in less the ideal space one has no choice but to try and take on subordinate coloration(I'm assuming the brown out is subordinate coloration).
Two my tanks are always contain quite a bit of contrast. Black background, white sand and green plants. I figure naturally a predator wants to blend in with his surroundings so being in a tank such as that may also help inspire a high contrast coloration on the fishes behalf as he tries to blend in. All just my opinion but hopefully it helps.
