the title is the only way I know to describe. I have a Duncan colony? If about 9 heads. One head wasn’t looking to chipper when I awoke and looking at its base looks as if the green “skin” is sluffing off. Only changes to speak of is the addition of another Duncan 3 heads and a very recent addition of an emeral crab and upped the light period from 7 to 7.5 hours a week ago. Any ideas? Course of action? Frag off?
