About 2 days ago I bought two corals for my tank (I am a beginner so im not that good at this stuff) I acclimated the corals like I should and I placed them in the tank. The elegance in the substrate and the pipe organ on the rock. The next day I came over and the elegance was still closed and the pipe organ still had its polyps retracted. So I thought they were still acclimating but on the next day they still were closed. One of my fish died on that day as well and there was a funky smell coming from the tank. My question is why are the corals still closed and was the funky smell my fish starting to decompose or something to do with my coral.
