I do not recommend feeding corals via the water column in a small tank. The reason being that it is very easy to pollute a small tank. When feeding the water column, most of the food doesn't even get to the corals - it ends up getting lodged in live rock and sand. Some corals benefit from water column feeding, but I don't suggest it in your tank. You can target feed corals by physically putting the food into the tentacles with feeding tweezers or dropping food through rigid tubing aimed at the coral, but I don't see any in your list that would benefit much from that. Corals like Open/Closed Brains, Plate Corals, Acans, Scolymia, Candy Canes, etc LOVE target feeding. Keep in mind that ANY food that goes into the system no matter what delivery method are nutrients that need to come out via skimming or water changes. It is very easy to overload a nano and end up with algae troubles.
