well yeah, any brand of frozen rotifers will do, if you looking for something else too beef it up the Aquasonic Seafood is a good all round particulate food, its not expensive, you do have to watch how much you feed as it can spike your phosphate a bit, but if your not heavily stocked then only a little bit will go a long way, if your in a Ultra Low nutrient state and your corals need it, especially if you have a heavy SPS or coral laod in general, then you will need more of everything but again, youll have to watch your nutrient.
Which of course all goes without saying, what im getting at is, variety is the key.
A good amino acid supplement will definitely also help as it will create a feeding response and generally get a lot more out of the food your feeding by helping the coral to not only take up more food (especially when broadcast feeding) but also to biologically utilize the food.
