After dosing some of the new food mix, I noticed some of my gorgs were capturing the bubbles in the water and ingesting them. They suck in each tentacle one at a time like a sea apple. I am wondering if the bubble is coated with the food, especially the Ultra Min D or Ultra Pac. Now sometimes they catch stuff in the water they don't want, and they just release it. They don't ingest it. Why do they ingest the bubbles, if they are even bubbles? Look close in some of the polyps and you will see. You will also see some "licking" each tentacle.
