What is this

[SOARnTACO]

So I heard leather coral but unsure. Seems to be a few kind of leathers.

Also where the best way placement for it in the tank I only know high flow but should it be high light

They like medium to strong flow but not direct strong flow. Medium to strong light as well. It kinda looks like a finger leather but the lights are to blue to get a good look at it. Do you have a picture under white light so we can see it better?
