All of those foods are good for now. As he hits the 6-8 inch mark I would stop with the Okiko Platinum as its protein content is too high for fish past their juvenile stages. If you are looking to see a faster growth rate I would incorporate cooked finely chopped shrimp into his diet once every 2-3 days in the morning feeding. I use cooked shrimp finely chopped and cooked crab with my fish and I see great kok and growth results from it.
