I feed my many gtba's everyday, they eat willingly, and there under a 400 watt 10k mh too. I am experimenting with 2x a day feedings. Anthonys comment was taken slightly out of context, he said that you shouldnt feed most anemones anything bigger than the size of a mysid shrimp, as they will spit it out at night, and the cleaner crew will nap it up and all the while the anemone isnt eating. often an anemone will expand itself to gather more light when it is nutritionally depribed and it will appear that all is well and its growing, but a little while later it mysteriously disapears. i would feed atleast once a week at the very minimum but recommend 3x a week. i use silver sides and just tear them into tiny pieces, or you could use a blender.
