So, son and I made a trip, Sunday, to check out a LFS people recommended. Nice place. Liked the people. We went into check it out and came out with our first coral, ever. Not exactly the plan. Nice little Kenya Tree. First night, one stalks kind of slumped over but next morning it was back up and looked good. It stands nice and opens up nice and appears happy. Water parameters look good and i adjusted lighting down a bit when we put it in. I do notice a hint of brown coloration. Is this something that happens when first transplanted or should I be concerned?
