CONGRATS On The Corals!!!
Everything seems fine. Even after you acclimate them to your tank, it'll take them time on their own to adjust to your tank. Remember, the lighting, flow, chemistry and the duration of lighting has changed for them. Kind of like jet lag if you moved to japan.
Mushrooms kind of do their own thing, similar to anenomes. Thats normal.
Most important!! Dont get down on yourself if you lose one or two from the adjustment. Sometimes they just dont make it no matter what you do. That being said, keep an eye on them, watch how they do, especially with the flow in the tank. Try not to move them around too much. Their strange. You can have leather hate flow, then another one live it. Just pay attention to them, but dont be an obsessive parent. Them them do their thing.
