I would say you have a pretty happy bubble there. I used to feed my big bubble coral brine shrimp, cyclopeeze, oyster eggs, daphnia.....they generally are pigs! Once they realize that you a willing feeder, I have noticed in my corals that when feeding time comes around, they sense my arrival and suddenly mouths start to open. It's actually an awesome phoenomina, but they have proven this to me time and time again. You can literally find the mouth on your bubble and feed it direct if you like, but be careful not to tear any of the delicate tissue on the coral. I use a baster. Once I learn where the mouth is, I simply put a bit of the tip between the bubbles and squirt some of the food into its mouth. Do not overfeed as they've been known to "puke" to much ingested food back into the tank. You don't want the foods to cause a swing in your parameters as the wasted food spoils. Have fun, but use care and caution. ...Angel :angel1:
