Hi everyone. I bought 2 ricordea yesterday, the one on the left has been in this spot the whole time. The one on the right was in a different, higher flow spot, and shrunk. I went ahead and moved it and adjusted my powerheads a bit to give less flow to the bottom of the tank. My two questions:

1) Is this normal for it to shrink when stressed? How can I differentiate the coral dying vs just shrinking

2) Will they be fine next to each other?

Thanks for the help!

After being in this spot for a few hours, the ricordea on the right is back to normal.

They'll be fine next to each other. Mushroom deflating and inflating happens a lot, sometimes due to stress, but not always. Eg when they poo they tend to contract/deflate. Mushrooms shrinking happens slowly over time, due to starvation usually.
