One of the items I use are nori sheets. That's that green looking seaweed sheet used to wrap some types of sushi.
Unless you have fish the require a lot of vegetable matter in their diet, you usually don't need to add too much in the way of vegetables. Take a look at what is in that package of dry fish food.
Some people that really get into feeding fish, usually if they breed them, will also culture their own live foods. White worms, wingless fruit flies, micro worms can easily be done in small containers.
