I am glad to hear that he is out and about now and doing much better. I would agree that you should start increasing the volume of water you are changing.
As for food you can give him chopped earthworms as another supplement as well as other types of frozen food. Frozen krill is a good one, but feed this sparingly and keep pellets as your staple food. Hikari makes a great cichlid specific sticks and pellets that are good for growth, color and overall health. I give my bichir the Hikari carnivore as it is high in protein and low in fat and has a good amount of fiber. All the fish foods list the nutrition content on the back and you want one for Skippy that has a good amount of protein and low fat. Also check out the ingredients on some of the foods. Tetra is not as low quality as Wardleys and Top Fin, but it certainly is not the best either. If you check the ingredients you will notice there are a lot of "fillers" mainly something that ends in the word "meal." Look for foods that don't list a lot of these, also look for ones that add vitamins. Giving a varied diet is a great way to keep him healthy. As I said earthworms are a great snack I give them to my bichir once a week or so as a fun live food. But do it too much and they get spoiled. Just remember to stay away from feeder fish from the stores as these are virtually nutrition free and can harbor disease and some theories say can lead to hole in the head.
For a really good source of info that you don't have to buy try MonsterFishKeepers.com. This is the sister site for big fish owners. Check out the Central and South American Cichlids section and you will find a lot of threads pertaining to Oscars. There is a great sticky in the Freshwater Illness section on hole in the head which is something every oscar owner should know how to identify and how to prevent, check that out for some good care advice and go from there.
