It "may" be a bit too much flow, but, the coral looks good, so i wouldn't worry about it for now.
Watch it though.
What I generally do is put my euphyllia in a location where they get an "up" current rather than a side current.
And i generally don't put them in the sand, usually mid tank.
But again, that's all dependent on your lights.
And don't have any reservations about moving a coral.
If you think a coral is not happy, just move it, you can always move it back.
I'm always moving things around.
I have one like yours, but mine was bleached and in sad shape when I got him.
He's coming around now though.
