Got my first wild Indo Acro colony in today. Surprised at how nice the colony looks, straight out of the box! However, after a 20 minute Bayer dip I was closely inspecting for pests and came across several of these odd things embedded in what looks like an old corallite. At first glance it reminds me of either a folded crab claw or a clam. Colony is in QT for the last 2 hours and nothing has changed with them. Anyone have a clue what these are??
