Its gotta be a tie for me between Dragon Eyes and the Jokers.
I got some Dragon Eyes and they were doing great, over the past few days they seem to be struggling though. Some of the polyps have turned brown and are kinda wilting away. I moved the colony a couple days ago into a little more turbulent area and they seem to be making an improvement but still arent opening very much.
Random side note, I had 2 colonies spawn in my nano and the result isnt horribly vibrant, but having something that has spawned out of my tank is AWESOME! Its still just a tiny single polyp I hope it grows out. Will post some pics when I get home from work.
