Well, when I said I was new to zoos, I mean I have had this colony for about three months, but don't generally have a lot of experience with them. I believe that they are fully acclimated though. I do know that I failed to properly anchor this piece to something stable and my emerald crabs and pep shrimp knock it around a lot. (I fixed that part though).
Last night they looked better than they have in a week or so, but still some were grayed out. We will see.
Thanks for the feedback.
