I've been target feeding my bubble and what's left of my candycane. (I lost all but three heads of the candycane last year in a heatwave.) Now I have 4 or 5 heads growing very slowly. I target feed with a turkey baster.
I feed a little of my home-made food:
Whatever seafood is on sale, last time it was shrimp, mussles, and whitefish. Plus a piece of nori, (from the sushi counter), a bunch of Formula 1 flake, and a big squirt of marine snow. (I know, I know. next time it's selcon and golden pearls!)
The corals love it. They suck in whatever I place by their mouth's. Then the next day they are all big and puffy! My shrooms and ricordia love it as well.
