I finally fed the thing tonight for the first time since getting it yesterday. I have seen some down right AGGRESSIVE corals before, for feeding, but when I fed each polyp it was easily in the top ten. I diced up some PE Mysis into a paste and mixed it with Cylcop-Eeze, when I squirt each head (I never touched it with the baster) it just SLAMMED DOWN on the food and sucked it all in within seconds.
