I found a mesh breeder cage that hangs on the side of the tank, it's not really large, but I put the sun coral in the cage to feed it, then I know it's getting food, nothing steals it from the 60+ polyps it has and any extra food stays in the net so I don't pollute the tank. I feed mysis shrimp, frozen Cyclop-eze, sometimes rotifers, all dilluted in SW and target feed the polyps. I also have it in its home spot in DT about 3/4 of the way down the tank and medium flow, kind of shaded from light. It opens whenever food is in the water and it opens at lights out, so I see a lot of it. It's awesome!
