It is best to use vitamins that are made from and come from sea creatures. There are many multiple vitamins on the market that fit this description. I would also include a fat supplement. Have you read through: http://www.reefsanctuary.com/forums/...nutrition.html

I would discourage the use of any land product, such as spinach, since the other parts of the spinach leaf are not digestible to marine fish and it contains the wrong kinds of carbohydrates that marine herbivores need in their diet. Feed seafoods to sea creatures.
