They have for sure gotten more red in them and the blue has gotten thinner. They have stayed very full though and good growth of polyps. I had a difficult time keeping acro frags in the beginning but the one that I have now is starting to grow well. Since I began ramping up the intensity the past few months. Around 3 months ago I overdosed on alk not paying attention to which battle I was pouring and that did a number on my Jedi mind trick but its recovering well.
